Triple Six: David’s 1975 Datsun 280z

Filed under: 240z,280Z,Featured Cars and Projects,Performance
by Alvin G @ 6:00 pm on June 19, 2020

 
We enjoy helping Z cars owners get their cars in top shape to Enjoy The Ride. David P purchased this 1975 Datsun 280z on the East Coast and the exotic shop it was at had difficulty with it. David moves between San Francisco and Massachusetts and wanted us to sort his Z out before hitting the roads here. Our Z Car Garage Big-Brakes and Z Car Garage CV Axles along with tuning and aesthetic upgrades transform this Z.

 

Affectionately called “Triple Six”, the Z arrived at our shop from the East Coast via Masney Auto Transport (Thanks David). David had not seen the Z in person yet since purchasing and it needed some attention, Z Car Garage style.

 

The car was not running upon arrival and Rob had many suggestions after the initial assessment. From David:

“When Rob called to tell me that my car had made it there I said ‘Ok great. Can I tell you what I want done?’ to which Rob replied ‘Nope’. He said ‘I want you to come down here, drive my car and then say to me, OK I want you to do to my car whatever it was that you did to yours’, and after driving his car I did say those exact words.”

ZCG Big-Brakes and CV Axles

 

Indeed, we had David test drive “Mrs. Butters”, our 1971 Series 1 240z shop demo car with full suspension and our ZCG Big-Brakes:

“I drove Rob’s unassuming, Safari Gold 240Z, that he appropriately named Butters, and God damn was it fun! I was surprised when he told me it had 275 horsepower, not a small number for a car that’s so small and light, its just that it felt much more powerful than I ever thought a sub 300 hp car could feel.”

 

After the test drive he was sold on our Z Car Garage Big-Brakes and Z Car Garage CV Axles! Butters has a way of doing this to our customers 🙂 Read below for a brief description of these parts:

    
 

As fellow S30 owner/racer Glenn C mentioned in his review, on top of braking performance, pedal feel is extremely important and our Big-Brakes deliver. This is a direct result of working with engineers at Stoptech to create a totally bolt-in solution requiring no M/C change or additional proportioning valve/adjustments. All fitting behind a 15″ Watanabe or Panasport wheel (and some 14″ wheels) and retaining factory emergency brake lever! A few details below:

Calipers: Stoptech ST42 4-piston front & rear race calipers (Alum 6061 mil-spec Type III anodized)

Rotors: 280mm x 20.6 with Alum 7075 hats

Pads: Stoptech 309 sport street pads

Blog posts documenting all of our customers running the ZCG Big-Brakes can be found HERE.

A few closer detail shots of the calipers, rotors and hardware:

 

We removed David’s brakes and installed our ZCG Big-Brake kit. Up front:

  
 

    
Our Big-Brakes utilize the OEM brake master cylinder and booster along with the factory hydraulic system. We installed a new master cylinder for David and fixed the wheel/hub area:

 

At the rear, the aftermarket disc setup was replaced with our ZCG Big-Brakes:

 
  
   
   
Factory handbrake functionality IS retained! A few close-ups of the front and rear setup:

 

Panasport Wheels

Complementing the new brakes on David’s Z are Panasport wheels! We replaced the generic aftermarket wheels with 16×7 Panasports and Bridegstone S007a tires in 225/50/16.

 

The new brakes fit nicely behind the new Panasports: We dialed in the spring set on the coil-overs and adjusted them for the best ride quality.

       
 

Our Z Car Garage CV Axles help transmit power to the ground and ensure smoother operation compared to your standard half shafts. We have over 100 CV axle kits on customer cars and we are stoked with all of the positive feedback.

 

David received axle set #324. Stock half shafts (L) and ZCG units shown below with more pictures in the gallery:

  
 

Details

To ensure that David could pick up his Z from us and start Enjoying The Ride immediately, we performed clean-up work on the interior and sorted the turn signals and headlights. Aesthetically he wanted to change a few things like the front end. We installed a Euro front bumper with Josh fabricating some brackets to make this 280Z look great:

 

David was blown away by the suspension and braking upgrades:

“I was completely convinced that Rob was not only the right one, but probably the only one that could bring my 1975 280Z up to its fullest potential. I say the only one because of the custom built Z car garage suspension and brakes that Rob uses. We agreed on a comprehensive upgrade to my Z that would be completed in two stages.  The first stage was completed this past March. The 45 year old suspension was, to say the least, upgraded. Because Rob believes in a holistic approach, the suspension work also included the proper brakes, wheels and tires. All of the components were specifically chosen to work together in order to produce a car that handles phenomenally and almost unbelievably well.”

Engine

 
 

The triple-Weber L28 simply received an ignition timing set, making 161hp/160tq at the wheels:

Enjoy this dyno video below with sweet L-series music:

 

Part Two

 

David reports that his Z went from junk to handling better than a 911. Here he is (above) Enjoying The Ride on Skyline near Alice’s Restaurant. What’s next for Triple Six? Full engine upgrade!

“The second stage, that we will be starting soon, will be the engine work. The goal is to get 300hp out of the old in-line six. Rob’s love the cars that he works on is evident in the quality of his builds. A true craftsman in every sense of the word.”

 

We look forward to working with you David, LONG LIVE THE Z!

Do It Yourself: Ken’s 1970 Datsun 240z

Filed under: 240z,Featured Cars and Projects,Performance
by Alvin G @ 5:49 pm on June 12, 2020

 

The Z Owners of Northern California (ZONC) is one of the oldest Z car clubs in the nation. We are proud to be a part of this group and support its members, like former ZONC president Ken C. Ken brought his 1970 S30 to Z Car Garage for a dyno tune and minor sorting. In true do-it-yourself fashion Ken performs most of the work himself, even installing a set of our Z Car Garage CV Axles in his garage.

 

“When I was 19 and in the Air Force I saved up for a Pinto, saved more for a Maverick…then I saw a 240z. I always wanted a 1970 and got this one in 1985. I drove it everywhere including Maine. I do 99% of the work myself with lots of details/upgrades like a huge cooling system (custom shroud) to support the A/C, rebuilt steering rack and all lightning.”

We recall seeing Ken’s Series 1 240z at the ZONC Annual Car Show in Brisbane, CA where he picked up an award for his efforts:

 

You can imagine how honored we were to have Ken let us work on his Z that only he’s allowed to work on. He had built a Rebello 3L with 5-speed/stock clutch and wanted us to do final sorting:

“Rob has always supported ZONC, done good work for its members so I trusted him to help get my Z in shape.  It was running too rich, stumbling and it would die when A/C  was turned on.”

 

Rob dyno tuned the L-series with SUs gaining more hp/tq and eliminating the hesitation Ken reported. The dyno plot shows his old L24 from a ZONC dyno day at the shop vs the current Rebello 3L now making a stout 183hp/191tq at the wheels. Enjoy this dyno video with sweet L-series music:

 

ZCG CV Axles

Z Car Garage is proud to offer a CV axle conversion kit for your Datsun S30 and 510. We have sold over 100 sets of axles, with customers installing and enjoying them on everything from street cars to full-blown IMSA racers. These CV axles will help transmit power to the ground and ensure smoother operation compared to your standard half shafts. Full details can be found HERE

 

Ken had purchased a set of our ZCG CV Axles and installed them himself.We love to hear from customers that are using our products and he reports that the axles were easy to install and well-engineered. Thanks Ken, and nice work:

“The ZCG CV axles—much smoother happy with less vibrations, best CV axles I’ve ever seen. It took me about 90 minutes to install. Super simple and easy and Rob is of course always supporting his own products with great service.”

 

Please contact the shop or visit our website to order your CV Axles!

 

Time To Enjoy The Ride

 

Ken continues to enjoy driving his Z, to shows or cruises and around town:

 

More inspiration for the Do-it-yourself’er…Ken is also restoring this ’72 S30 back to its stock blue/white in his garage (and kitchen)!

 

Thank you Ken for entrusting your Z to us. Ken is an avid baker and makes his own jerky, we also thank him for the cookies (which he’s known for) and snacks he provided to the ZCG crew. LONG LIVE THE Z!

Yoni’s 1972 Datsun 240z

Filed under: 240z,Featured Cars and Projects,Performance
by Alvin G @ 9:53 pm on June 2, 2020

 

Yoni has been our customer since 2014 and after having a taste of vintage Z cars at the shop he finally found one to call his own. This green S30 has had a long history with ZCG and before Yoni picked it up he requested intallation of our Z Car Garage Big-Brakes and Z Car Garage CV Axles to make it perfect.

 

This Z was previously owned by our customer Alan L who purchased it in Idaho in 1995. We worked on this car since the late 90’s and it has many neat parts suiting his taste like a nasty 3L mated to a 4-speed transmission, stock brakes with race pads, Panasports and roll bar. He drove the wheels off this thing not only on the street but at the track too. In 2013 Alan retired to Palm springs and decided it was time to sell, sending it to us to find the Z a new home.

 

We got it here and installed a Rebello 2.9 with SUs, early 5-speed trans and some cleanup work.

 

Timing worked out wonderfully as Yoni was jonesing for an S30:

“I got my G37 in 2013 as a gift to myself for graduating college and landing my first “big boy” job. I researched the best garages in the Bay Area and only one stood out: Z Car Garage. I sent my first email to Rob in 2014, and my journey with ZCG has continued since then. Over the years I’ve only brought my G to Rob and his amazing team. They’ve performed all my routine maintenance and a couple major repairs and realized I appreciated the car as it is. It fulfilled it’s purpose for me – a fun, fast, reliable daily driver…

 

… Around 2019 I considered selling my G. There was nothing wrong with it, but I felt like something was missing for me. At this point I had spent the majority of my career developing electric vehicle technology (and even an electric flying taxi!). Spending so much time thinking about what was coming next made me, ironically, want to drive something more physical. I wanted to be able to experience driving something with personality, something that required actual skill and gave real feedback. I wanted something more rewarding…”

 
 

The Butters Effect

 

After a routine visit to ZCG and seeing all the vintage Z cars, Yoni took our shop demo car “Mrs. Butters” for a spin. It solidified his need for a Z:

“Rob eventually he let me drive one of his personal cars, Butters. The thing about driving Butters for the first time, especially if you’ve never driven a Z car, is that it’s totally unfair. Butters is kind of like the best version of what a Z car should be. It’s not another LS swap, not a restored garage queen, just a solid Z with a big engine and killer brakes. Butters is like the gateway drug of Z cars – you leave expecting all Z cars to be like that.”

Fast forward a few months and Yoni was ready to purchase the green Z. The 3.1L was already transplanted into customer Jason’s ProjectZ and the freshly built 2.9L with SUs and early 5-speed took its place:

 

Rob dyno tuned the L-series, now making 175hp/190tq at the wheels:

 

Enjoy the video with sweet L-series music!

 

 

The Z was good, but not “ZCG-good”, so we fixed that. Before it went home he had us install our ZCG Big-Brakes,  ZCG CV Axles, new Bridgestone S007a tires and more:

“When Rob showed me the car for the first time, I was mostly sold. The car was great, but the stock brakes needed to go (thanks to Butters). The car had a huge binder of records and history that went along with it. The price was right and we agreed that Rob would install ZCG big brakes, CV axles, and some sticky tires before I took delivery. He also took care of a few small items I wanted.”

ZCG Big-Brakes and CV Axles

We handed Yoni the keys to “Mrs. Butters”, our 1971 Series 1 240z shop demo car and he was sold on our Z Car Garage Big-Brakes (for small wheels) and Z Car Garage CV Axles! Butters has a way of doing this to our customers 🙂 Read below for a brief description of these parts:

A few more items were sorted including bumper over-rider removals, corrected side markers and replaced antenna

      
 

Welcome to the Z car family!

 

Yoni and his super supportive wife picked up car and they were stoked. Now he has a rad vintage 240z to go along with his daily G37 coupe.

“I’m really happy with the car. It’s the perfect compliment to my G, which I am definitely keeping now. It’s also really the best mix of things I wanted in a first Z. A good engine, moderate suspension upgrades, awesome brakes, and nice but not perfect paint. It’s something I can really enjoy driving and sharing with people without being paranoid about keeping it perfect. At some point I’ll be back to have Rob work on the interior with me. Who knows, maybe there’s a set of triple Mikuni carbs in my future. For now though, I’m enjoying the ride.”

 

Thank you for your continued support an we love working with you Yoni. We are glad that you are now a 240z owner,  welcome to the family and LONG LIVE THE Z!

Daisy’s 1972 Datsun 240z

Filed under: 240z,370z,Featured Cars and Projects
by Alvin G @ 4:34 pm on May 22, 2020

 

We had the pleasure of working with Daisy to help get her 1972 Datsun 240z back on the road. Our Z Car Garage Big-Brakes and Z Car Garage CV Axles along with upgraded suspension parts transform this Z into a fantastic sports car.

 

Before we dive in to the upgrades let’s take a look at Daisy’s story:

“My Z history actually started with a 370Z–it was my first car, bought even before I knew how to drive a stick. When I was ready for my next automotive chapter, I tried to think of another beautiful, fun, sporty coupe that wasn’t going to cost 60k, and realized it was my car’s great-great-great-etc-grandmother–the 240Z. So I was on the lookout through Craigslist for almost a year, in search of an S30 that hadn’t had a ton of performance work done to it already, but was still in overall good shape…

… I migrated to eBay and found my car in Texas. I have a vivid memory of standing in a drizzly parking lot a 7AM on a Sunday, watching the car transport guy reverse the Z up a slippery metal ramp to get it off the truck. I chugged it around the parking lot to get a feel for everything, couldn’t get the seat close enough to the wheel and had a TERRIFYING drive back to San Francisco. But I was obviously, already in love…I spent a couple of years really doing the bare minimum to get the car roadworthy, and it was a real champ, flawlessly performing on one very hot and sweaty drive to and from SoCal, but it started to feel like I wasn’t using the car as much as I’d like because it simply wasn’t practical–the suspension was super soft, we were getting tons of cabin fumes, the brakes made my parents incredibly worried (ha!) “

 

Daisy was looking for a shop to take care of her 1972 Datsun 240z  and heard about ZCG from a few different sources–the Z Car FB group and from following Courtney Frisk (Cutchen) the automotive photographer, who’s also worked with us:

“I knew that it was time for some more significant work, so I got in touch with Rob. Ultimately, the goal was to make this a capable daily driver (though I only really use it on the weekends)–not super powerful, just safe(r), reliable, capable, reasonable to drive on contemporary streets–a joy to drive.” 

Daisy brought the Z in late last year and we performed a full inspection.


The inspection revealed many items to be addressed from brakes, suspension to carburation which was really off. Initially we spent a few hours getting it driveable while we put together a plan to add some ZCG touches to her S30.

ZCG Big-Brakes and CV Axles

We handed Daisy the keys to “Mrs. Butters”, our 1971 Series 1 240z shop demo car and she was sold on our Z Car Garage Big-Brakes (for small wheels) and Z Car Garage CV Axles! Butters has a way of doing this to our customers 🙂 Read below for a brief description of these parts:

    
 

As fellow S30 owner/racer Glenn C mentioned in his review, on top of braking performance, pedal feel is extremely important and our Big-Brakes deliver. This is a direct result of working with engineers at Stoptech to create a totally bolt-in solution requiring no M/C change or additional proportioning valve/adjustments.

Pads: Stoptech 309 sport street pads

Blog posts documenting all of our customers running the ZCG Big-Brakes can be found HERE.

A few closer detail shots of the calipers, rotors and hardware:

 

We removed Daisy’s stock brakes and installed our ZCG Big-Brake kit. The chassis was treated to a full suspension rebuild with new parts, bushings and a full coil-over (Koni) suspension from Techno Toy Tuning. T3 finishes the suspension in our signature color and we really appreciate Gabriel and his staff. They make some of the best suspension parts out there for Z cars.

 

ZCG Big-brakes and T3 coil-overs replacing stock setup up front:

    
 

More pictures of the front suspension refresh with T3 T/C rods and lower control arms, ST sway bars, rack bushings and f/r wheel bearings. We also replaced the steering coupler:

 

At the rear, the factory drum brakes were replaced with our ZCG Big-Brakes. Factory handbrake functionality IS retained!

 

Rear T3 lower control arms, and more refreshed suspension parts and rear Big-Brakes also shown:

 
 

We replaced the brake booster and master cylinder with NOS parts: our Big-Brakes require nothing more than the factory hydraulics!

 

Daisy really wanted the look and feel of Mrs. Butters Z without being too low or riding rough. Mission accomplished: the Z looks fabulous from any angle:

 

Our Z Car Garage CV Axles help transmit power to the ground and ensure smoother operation compared to your standard half shafts. We have over 90 CV axle kits on customer cars and we are stoked with all of the positive feedback.

 

Daisy has CV Axle set #329. Stock half shafts (L) and ZCG units:

 

More pictures of the ZCG axles installed, also visible are the T3 control arms and re-sealed diff:

 

Engine

With suspension sorted, Daisy signed on for a major service tune since we had trouble getting it to run correctly. We replaced the plugs, plug wire set, cap/rotor, fuel filter, replaced VC gasket, installed a MSD blaster2 (black) coil and performed a valve adjustment and oil/filter change.

 
 

We replaced intake and exhaust manifold gaskets with factory Nissan parts and few ZCG tricks including a certain exhaust nut and exhaust stud.The exhaust manifold was replaced with an MSA 6-1 coated header and our ZCG exhaust system with stainless resonator and slash-cut tip

 

Details


A few more items were sorted:  the differential was resealed with new front/side seals:

 

The Z was cut/buffed with a detail. Finally, the tension springs for hood were replaced and the Z now ready for Daisy to pick up.

 

Driving is Believing

When Daisy and her fiance picked up car, they were blown away:

“I’ve only had the Z back for a few days, but it’s incredible! I knew Rob’s tuning was great from the first “check-up” he did on the car, but getting the car back with the Big Brakes, the new suspension, and axle kit–it’s honestly like a new car. My fiance and I were finding ourselves bracing for the bottoming-out-scrape we’ve become used to from the old suspension, and the Z now just sails over them! The exhaust note is beautiful, I can stand behind the car without choking on fumes, and it’s what I really hoped it would be–both practical, and a joy.”

 

The Z was a big part of their engagement photographs in the hills above Bolinas (photographer, Helena Martin)

 

We enjoyed working with Daisy and she’ll be back for either triple-Mikuni’s or rebuilt SU’s and some dyno tuning:

“Working with Rob and ZCG in general is what working with a shop should feel like. When I first got in touch with Rob, we had a detailed “intake” conversation about what I was looking to accomplish with my Z. This was an early, awesome indication that ZCG really values listening to what customers want, not just churning out identical builds or upgrades, or pushing one kind of perspective. While I’d heard that lead times working with ZCG could be long, Rob was always available to chat and check in, answer a question about the work, or listen when I found a new nit to pick about the car. Rob is also just an excellent guy–It’s clear to anyone who’s met him that he’s deeply passionate about this work, and it’s infectious, even for folks who have already caught the Z bug.

Thank you for entrusting us with your S30, Daisy. We are so fortunate to work with owners that appreciate the Z and believe in our ability to make them better! LONG LIVE THE Z!

PROJECTZ: Jason’s 1971 Datsun 240z

Filed under: 240z,Featured Cars and Projects,Performance
by Alvin G @ 6:01 pm on April 24, 2020

 

Being part of a client’s project from start to finish is just one of our favorite jobs at Z Car Garage. Jason P contacted us a few years ago to help find a 240z to call his own and what began as a visit for our ZCG Big-Brakes evolved into building his dream car. Let’s take a closer look at his “ProjectZ” that received a ZCG-style mechanical restoration including a new drivetrain, engine bay clean-up, total suspension rebuild and more.

Jason’s Z Story

We are lucky to work with long-time Z owners and first-time enthusiasts like Jason. It’s no surprise to hear how the Z struck a chord with him at a young age:

“My favorite toy growing up was an old beat-up Transformers Bluestreak I inherited from my cool older cousins. I found out years later this toy was based on a Silver Datsun 280zx and it’s been my dream to get one someday, for the past 20 years I’ve been patiently saving and loosely looking. As weird reminders I’ve done things like make a lego 240Z for my desk to stay passionate about the car.” 

 
 

Jason recalls how he found us:

“I was looking for a shop from the Bay Area to San Diego that specialized in Zs and who could be a long-term partner in building and maintaining my dream car. I found ZCG on multiple forums and Yelp with stellar reviews and feedback from other Datsun owners.  A couple clicks later I was reading the ZCG blogs and loving how thoroughly the builds were documented. I loved the first time talking to Rob and how he never mentioned any of the prestigious work they had done and was solely focused on what I wanted. Maybe the second time we talked I heard him sing and that sealed the deal.”

 

Through many discussions about budget and goals we started the search for a chassis to build on. Jason drove one of our older performance-built Z’s and instantly became hooked on triple-Mikuni’s and chassis upgrades…but he was adamant that the color must be silver. He found a local S30 that we inspected and belonged to ZONC member Robert C. It’s a small world and we actually worked on this car in the past. Jason purchased the Z and shared what he liked/disliked about it with a few revelations gained after driving a stock S30:

 

Jason was very specific in his vision for the build:

“My goal was for a resto-mod that would mainly be used to cruise but had the power to kick-ass if needed. It was important to me that some parts of the car like exterior and interior were factory and original and other parts like brakes, suspension, engine were upgraded for better comfort, performance, and safety. This was really clear to me after driving an unmodified RHD Fairlady Z and unmodified series 1 240Z. The 50 year old suspension creaked and bounced, I had to leave huge gaps driving in rush-hour traffic so I could stop on time, and I really love the L24 but it didn’t feel like I was driving a sports car by today’s standards.”

 

 

Taking the Z to the next level

 

Engine

Following Jason’s desire for more power, timing was perfect and a 3.1L that we had done for a customer a years ago became available. We took this entire driveline and installed it in Jason’s Z. Here is the tired, stock L24:


The freshened 3.1L was built by Techcraft many years ago with a P90 head,  rare Clifford 6-3-2 header, triple-Mikuni ph44s on a Harada intake manifold, serial #245 ZCG Heat Shield,  280zx internally regulated alternator and gear-reduction starter, MSD6Al with tach adapter and black coil, and 2.5″ exhaust with a Borla XR-1 muffler:

 
 

With the engine/transmission removed we focused our efforts on restoring the engine bay.  All hydraulic lines were removed and zinc’d with many other parts that were bagged/tagged. More pictures in the gallery below:

 

Before/after plating hydraulic lines:

 

New engine bay parts included: all new fuel system, coolant hoses, fuel filter, Koyo race radiator and all drive belts:

 
We cleaned up the entire underside and undercoated the chassis. Freshly plated hardware and lines are shown.

Before/after:

  
 

The fuel system was replaced and gas tank removed as it was in rough shape. We replaced it with a clean unit from the ZCG parts stash. All the fuel vapor/recovery lines in the gas tank area were replaced:

  
 

This was a 4-speed car, so we grabbed one of the 5-speeds from Rob’s stash. This early 280z 5-speed is like a 4-speed but adds a 0.86 overdrive. The factory 3.36 R180 factory rear end will be upgraded later.

 

With the drivetrain out we installed a JWT aluminum flywheel with HD clutch for the L-series. We use this setup exclusively and it has really good feel with an organic clutch that’s also a breeze in traffic. The key to success to having a powerful vintage car is that it can also be easy to drive.


More detail work was performed:

 

Engine bay before/after:

 

Dyno Tuning

 

Rob dyno tuned the 3.1L now producing 221hp/226tq to the wheels on 91 octane. Great torque and makes all the right sounds!

 

Jason was stoked on the new drivetrain:

“Lucky to have a “purist” 3.1 stroker that looks right at home in the engine bay thanks to the original Nissan and Datsun parts combined together expertly. The triple Mikuni’s sing all through all 5 gears and I’m super impressed by the clutch Rob chose for me and how responsive the throttle is. I can’t wait for Winter now to try cold starting, I’m not going to miss the choke lever at all.”

Enjoy the video below showing the dyno run and test drive with Rob, volume up!

 

Chassis and Brakes

 

Jason originally came in to ZCG for our Big-Brake kit and it was just the beginning of his wishlist.  Now that we replaced the engine it was time to match the power level with braking and suspension upgrades.

ZCG Big-Brakes and CV Axles

We are proud to have several of our ZCG products on Jason’s 240z. We installed our Z Car Garage Big-Brakes (for small wheels) and also upgraded to Z Car Garage CV Axles! These products have been standard on numerous ZCG builds.

  
 

As fellow S30 owner/racer Glenn C mentioned in his review, on top of braking performance, pedal feel is extremely important and our Big-Brakes deliver. This is a direct result of working with Stoptech to create a totally bolt-in solution requiring no M/C change or additional proportioning valve/adjustments. All fitting behind a 15″ Watanabe or Panasport wheel and retaining factory emergency brake lever! A few details below:

Calipers: Stoptech ST42 4-piston front & rear race calipers (Alum 6061 mil-spec Type III anodized)

Rotors: 280mm x 20.6 with Alum 7075 hats

Pads: Stoptech 309 sport street pads

Blog posts documenting all of our customers running the ZCG Big-Brakes can be found HERE.

A few closer detail shots of the calipers, rotors and hardware:

 

We removed Jason’s stock brakes and installed our ZCG Big-Brake kit. The Z also received entire full coil-over (Koni) suspension from Techno Toy Tuning. New parts included adjustable T/C rods, rear control arms, new bushings, rack bushings, steering coupler, ball joints, new f/r wheel bearings and more. T3 finishes the suspension in our signature color and we really appreciate Gabriel and his staff. They make some of the best suspension parts out there for Z cars.

 

We went ahead and got Jason dialed in with the ZCG big-brake kit for small wheels with parking brake and a new brake booster/master cylinder. More pics in the gallery!

At the rear, the OEM drums brakes were replaced with our ZCG Big-Brakes. Factory handbrake functionality IS retained!


Great feedback from Jason on the Big-Brakes:

“ZCG front and rear BBK dramatically improved the stopping power over stock 240Z brakes, I don’t need to worry about constant drum-brake servicing and can feel all 4 tires stopping when I pump the brakes now. I’m more confident driving it freely knowing it can stop at shorter distances and not wreck a car that took so long to find and with so much work done to it.”

 

Our Z Car Garage CV Axles help transmit power to the ground and ensure smoother operation compared to your standard half shafts. We have over 80 CV axle kits on customer cars and we are stoked with all of the positive feedback.

 

Jason received ZCG CV Axle set #321:

Panasport Wheels

 

Our ZCG Big-Brakes also look great behind Panasport wheels in our offset allowing us to run 225/50/16 tires.  We replaced the generic wheels with 16×7 Panasports and Bridgestone S-04 tires. We think the wheels/tires are a huge improvement:

 
 

Jason was pleased with the chassis upgrades:

“Car feels amazingly tight now, it doesn’t creak anymore going over bumps and feels firm entering and doesn’t bounce as much when exiting corners. I’m glad we were able to upgrade so much of it at the same time, the overall suspension package Rob recommended handles so well and really changes the character from a stock 240z.

Interior

 

The interior got attention as well. We pulled the entire dash and cleaned up the heater controls, pressure tested the heater core, refurbished the heater box, cleaned up the gauges and replaced all light bulbs. We ensured that we never have to go into the dash again.

 

This is our second Vintage Dashes installation and we thank Ivan Jaramillo for making a cost-effective product for Z cars. More pictures in the gallery below. Expect a full report on their products soon!

 

Details

 

The little things are what we excel at. Jason didn’t like the odd, 280zx vented hood so we gave him a NOS S30 hood from Rob’s stash and had our man William paint it. He also touched up the front end:

 

Jason was not fond of the PO’s aftermarket radio/speaker boxes in back.  We removed it all and gave him a factory 240z radio. Also shown below: powdercoated rear sway bar hangers for ST parts, zinc’d pieces.

Enjoying The Ride

Jason was super stoked on his Z and immediately started driving it everywhere. Here is a message he sent Rob, it’s hard to beat enthusiastic clients:

“ZCG is an extremely popular shop and I consider myself super fortunate to be living about 25 minutes away. In my occasional visits I’ve seen everything from 510 wagons, supercharged 350zs, and 240z restorations and upgrades so I know they can do it all. The shop is very clean and organized and filled with all sorts of history and treasure for Datsun + Nissan enthusiasts to nerd out on.
Despite how busy ZCG is, Rob and crew didn’t miss a beat with my car with awesome communication and recommendations, just picked it up yesterday and loving it! The care that went into this car would be appreciated by anyone into details and craftsmanship and it’s clear the years of expertise Rob and crew bring to their work.” 

 

 

We really had a great experience working with Jason and we thank him for letting us build his ProjectZ.
“As a novice car-guy I feel Rob and team really understood my needs for a clean restomod that was easy to drive and could haul if needed. The entire car is super impressive and I find myself daydreaming about driving it around now. “
