Dave L comes from Carmel Valley and he visited Z Car Garage for suspension upgrades on his 1972 Datsun 240z. Prior to meeting us he added many parts to the car himself like a 5-speed transmission but needed our expertise for Z-specific parts. Our Z Car Garage Big-Brakes and Z Car Garage CV Axles along with a dyno-tuned 2.8L L-series really transformed this pretty S30.

  

Suspension

 

The chassis was treated to a full suspension rebuild with new parts and bushings 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.

Stock vs T3 T/C rods up front:

 

Stock rear lower control arms were replaced with T3 adjustable units:

 

Dave provided us with a set of Tokico/springs from back in the day. We installed new tie-rods, Nissan ball joints, rack bushings, bump stops and moustache bar bushings:

   

 

ZCG Big-Brakes and CV Axles

 

Our readers are likely familiar with “Mrs. Butters”, our 1971 Series 1 240z shop demo car with full suspension and our ZCG Big-Brakes. Following a test drive in Butters, clients are sold on our Z Car Garage Big-Brakes and Z Car Garage CV Axles! 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 Dave’s stock 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. A few more shots of the front setup:

 

At the rear, the stock drums were replaced with our ZCG Big-Brakes:

  

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

 

Following the suspension and brake installation was a full alignment:

 

The new ZCG Big-Brakes fit nicely behind the 15″ Ansen Sprint wheels:

 

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.

 

Dave received axle set #291. Stock half shafts and ZCG units shown below with more pictures in the gallery:

We met Greg a few years ago at a Blackhawk Museum gathering where famed Peter Brock (BRE) was speaking. Greg told us that he found a clean, low-mileage 280z and he was really interested in ZCG going through it. After he visited the shop we discussed our previous 280z builds (Cece, Gary and the Roth’s) and got to work building a Z for Greg that would reflect his tastes while keeping the vintage vibe. This 1977 280z was treated to a ZCG-style mechanical restoration including a new drivetrain, engine bay restoration, total suspension rebuild and more.

. 

 Drivetrain

 
Greg’s Z received a total engine bay restoration along with upgrades to the driveline for smoother driving and improved torque.  Please visit the gallery below for more pictures documenting the engine bay restoration work, it’s where our efforts shine!

Engine

A fresh 3.1L  engine with new injectors replaced the tired L28:

 
New L31:

    

With the engine/transmission removed we focused our efforts on restoring the engine bay.  Everything was zinc plated or powdercoated.  New parts included brand new injectors, all new fuel system, hoses, fuel filter and all the drive belts.

 

All new hydraulic lines, emissions plumbing and more engine bay clean-up (full re-paint) before/after. More pics in the gallery!

  

Intake manifold cleaned up and powdercoated:

 

An MSA exhaust header was installed:

 

 

At the time we had a 280z 5-speed in our stash but Greg is so particular(we love that) and the unit was gone through by Z car transmission expert Steve Pettersen:

  New clutch/flywheel:

 

With the new engine/transmission even more detail work was performed:

 

MAF/hose/hardware detail:

 

Engine bay restoration, before/after:

Dyno Tuning

 

Rob dyno tuned the rebuilt 3.1L engine making 169hp/179tq to the wheels:

Enjoy L-series music on the dyno!

Suspension

 

Greg wanted a fantastic driver that was worry-free. We replaced all of the hydraulics and front/rear suspension assemblies to match the new driveline.  All suspension was either zinc’d or powdercoated:

  

We installed KYB strut inserts with lowering springs, Suspension Techniques sway bars, Techno Toy Tuning adjustable rear lower control arms, TC rods, and rack bushings, all new wheel bearings and new ball-joints. We do offer a full coil-over setup for track day/performance-oriented customers, and this spring/strut upgrade for those that want a better stance with improved handling without getting beat up.

Suspension refresh with T/C rod and steering rack detail:

     
Rear end with T3 lower control arms in:

 

 

We modified the floor to accommodate Recaro LXF Specialist seats (in leather) to suit Greg’s height while maintaining full seat travel/movemen:

  

New center console, MOMO competition wheel and restored the A/C ensuring it blowed cold (R134A):

  

Details

 

The little things are what we excel at. Exterior items include re-chroming both f/r bumpers and adding Hella H4s with our HID kit. Other interior items include a new tach and making a little seat belt holder clip to work with the Recaros:

 

Please check the gallery below for more detail shots, there are too many to list in this blog post!

Enjoying The Ride

 

With all the attention to detail and upgrades this 280Z can drive comfortably in style with power. Despite common opinion on the 280z, we think it has a wonderful character from that era and when you update similarly as a 240z, they are great sports cars. The majority of our 280z costumers still use their cars as daily drivers (Cece, above).  Greg is super happy with how it came out and he has a smile on his face every time he drives it.  The engine is torquey,  you can stop on a dime and it handles well without riding harshly. Thank you Greg for letting us help build your vision of the ideal 280z.

LONG LIVE THE Z!

On Saturday I joined six other cars for a morning cruise through the Santa Cruz Mountains. The two S30 Z cars with us were running our Z Car Garage Big-Brakes (for small wheels) and Z Car Garage CV Axles!

Glenn’s 1972 Nissan Fairlady 240z-L

 

Glenn Chiou drove his RHD Fairlady Z sporting our Z Car Garage Big-Brakes (for small wheels). He is an avid vintage race car driver/restorer and found our brake kit offers incredible brake feel and performance all fitting behind his favorite 15×8 zero offset Watanabe wheel:

“The most important aspect to me when it comes to braking on a street driven car is feel. Yes, stopping power is extremely important, but also is not that difficult to achieve on an early Z car that is naturally light to begin with. Feel, however, is something that has always managed to escape me and the ZCG brakes deliver. WOW, what a difference. The feel, modulation, power, sharpness was amazing. Hands down the best brakes I had ever driven on a Z car”

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 pictures of the Big-Brakes being installed on Glenn’s Z:

 

Glenn was having fun on the twistys on our cruise (see video below). Learn more about his Z in this Petrolicious video.

 

James’ 1972 Datsun 240z

 

James is running our ZCG BBK (1st gen, 328mm) and  Z Car Garage CV Axles in his turbocharged L-Series beast:

 

 

You can learn more about this 560whp Z on Speedhunters and see it in action on Hoonigan Autofocus. James also had a blast on our Saturday cruise:

 

Saturday Cruising

 

We started our drive in Downtown Saratoga and made it to the coast via Bear Creek and Bonny Doon Rd. Here is a short video:

 

We were happy to enjoy the company of cool cars and cool folks, also joining us:

Dustin’s 510

 

We’ve known Dustin and Courtney for many years. Dustin’s 510 4-door runs a KA24DE and sweet Longchamp XR-4 wheels. The side exit exhaust is loud!

 

Tony’s Mazda RX-2

 

Tony has had this RX-2 for many years. In addition to the full restoration it now has a full (S5) 13B drivetrain with a Ford 9″ rear end! It is mint. I haven’t seen Tony in many years so it was a joy to have him along:

Lloyd’s AE86

 

Lloyd has a very cool collection of cars and this AE86 is the latest. Although it sports an F20C drivetrain (Lloyd promised me it’s not the same car as this one), it has numerous upgrades for a better drive. Gotta love TE37s:

 

Geoff’s BMW 2002

 

Geoff’s no stranger to our Bay Area cruises and also owns a Lotus 7. He was the only German this time with his BMW 2002 on rare Campagnolo wheels:

 

I drove my SR-powered ‘67.5 Datsun Roadster and it was a great way to spend the morning.

 

Yes, that’s a Ferrari 250 GT Lusso flying by on HWY 1!

Dan F is long time customer of Z Car Garage and we started working with him shortly after he acquired his Nissan 350z. Dan comes from a family of motorsports enthusiasts with his Dad (C6 Corvette) and brothers all enjoying track time together:

 

In 2012 we installed a Vortech Supercharger and for the next five years Dan regularly tracked this Z33. We fought with oil/water temperature and anything you can think of battling while at the track. Where there was an issue, a solution was devised so he could beat on this Z for 20-30minute sessions easily.

Better, Stronger and Faster

In 2017 with 53k miles on the odometer the factory engine failed in Turn 1 at Laguna Seca. We were at a crossroads: with all the developments we made so Dan’s Z could handle routine track duty should we push the envelope by adding even more power?

 

The answer, invariably was YES. At the heart of the new build was a Rebello VQ with HR top end and internals including forged pistons and rods, HR head gaskets and headbolts, race bearings, factory compression ratio, JWT C8 cams and JWT HD valve springs:

 

The major power added was a new Vortech Si wheel offering more hp per pound of boost. Supporting mods included DC sports carb legal headers, EV14 1000c injectors, GT MAF and upgraded fuel pump. Keeping things cool are new oil coolers and a revised ZCG cold-air intake:

   

The front-mount intercooler was upgraded to an ATP Garrett 900hp unit:

 

To monitor intercooler efficiency a gauge was installed in the factory cubicle displaying temperature before and after the IC:

 

A few more pics of Dan’s interior:

  

Dyno Tuning

 

With the engine bay all buttoned up Rob dyno tuned the Z using UPREV. The Z is now making 480hp/390tq at the wheels on a conservative track tune to keep heat low. The dyno plots show the previous 91 octane tune (368hp/333tq) and newest 91 octane tune (455hp/365tq):

 

More Track Mods

 

An off at Thunderhill gave Dan an opportunity re-engineered his aero pieces. He rebuilt the front splitter, added side blades, rear diffuser and front fender slats:

 “For the brake ducts I repurposed old Roush Nascar ducts in dry carbon with standard ducting. The front splitter with spats I made to attach to the Stillen piece. The spats are tied in up the fender to prevent turbulence with the tire as it’s running a 295 front with -3.6 degrees camber.”

 

“Rob has been part of the heart and soul of this car as he has helped me build it over the last 10 years. It has been a guinea pig at times to try new methods but he has been a great partner and sponsor through all of it. It’s very fast and very fun being quite easy to handle at the limit. It is maintained for track duty at ZCG.”

 

Here is a video of Dan autocrossing and running the Z at Laguna Seca, there is even a snip from Larry Chen’s Hoonigan Autofocus :):

 

Our shared excitement is seeing Dan making personal bests at the track.  Dan is fast and here are a few notable times and achivements at his favorite tracks, we are proud of him!

“I’m still looking for time to break 1:40 at Laguna Seca, currently at….140.7 and 123.7 at Thunder Hill West. I’ve consistently run in the top 10 of 100 with Santa Clara Corvette Club AX’s”

 

  

We have even seen Dan on the street at the local 2018 ZONC Annual Car Show and cruising twisty Bay Area roads near Alice’s restaurant:

 

Thanks for supporting Z Car Garage and letting us build your track car Dan. We look forward to seeing you enjoy track events. Long Live The Z!

 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:
