Ruth and Larry Roth have been part of Z Car Garage since 2008. Over the years we performed a full mechanical, interior and exterior restoration on their 280Z and late last year Ruth reached out to us because it wasn’t running well.  She also shared the unfortunate news of her husband Larry’s sudden passing. For the first time in 50 years she was on her own, with her Z car.

 

Remembering Larry

We are personally invested the cars and people we conduct business with at ZCG. Rob set aside time to make a house call and visit Ruth out in Menlo Park to assess the Z. It sat around for a long time and had signs of headgasket issues. The Roth’s enjoyed the Z for many years adding their own personal touches and with all the ZCG restorative (paint/interior) work, we were at a crossroads with this engine failure.

 

Ruth bought this car brand new and we wanted to not only celebrate Larry but also make the Z drivable again for Ruth to enjoy on her own. The plan was to rebuild her engine (stock style 2.8) and update the chassis with our Z Car Garage Big-Brakes and Z Car Garage CV Axles to make it perfect.  Before we get into the latest work let’s take a look back on the interior/exterior refurbishment.

Interior

 

The dash was removed and sent out for restoration and when it came back we replaced all the gauge lights with updated LEDs. We polished all of the plastic covers, resealed all the heater ducts, and lubed all the heater cables. We also serviced the heater core, replaced all the heater hoses and anything easily accessible while the dash was out.

A set of RECARO LXFs in leather replaced the factory seats:

To complement the seat choice we picked a custom carpet kit and leather for the new door panels and headliner. Another nice touch was the new door panel trim matched the other door panel parts perfectly. More highlights include a new factory center console fitted with an updated HD headunit, MOMO steering wheel, and custom shift boot (Ruth’s choice). Check out detailed pictures of the interior work in this blog post HERE.

 

 

Exterior

 

We met the couple in 2008 when Ruth came in to ZCG for a mechanical refresh.  All hydraulics (brakes/clutch) were restored. The suspension was treated to urethane bushings and Tokico 5-way struts with Eibach springs and a set of beautiful Panasports. Finally, we cut and buffed the paint and Ruth’s Z took on a new look…it was almost like 1978 again! It had been years since we had seen the Roth’s other than routine maintenance. It was time to dive back into the project with a full external restoration.

   

We called upon our man William from William’s Auto Body and both Ruth and Larry had two requests: 1) The Z car must be as awesome inside as outside and 2) we absolutely must keep the pinstriping that had been on the car since new. William was more than up to to the task. This time we went ahead and installed electric power steering for ease/use, our upgraded rearview mirror (as featured on Gary Roser’s car, report later) which includes a backup camera, GPS, temp:

 

Re-chromed bumpers and restored guards:

  

Full glass/chrome trim/weatherstrip R&R. All NOS Nissan!

 

Inner fender liners:

 

NOS emblems replace pitted/fading orignal pieces:

William applied the factory paint color and the Z looks fantastic. Finally a set of powder-coated louvers and a full detail really make this 280z standout.

Engine

 

Fast forward to January 2020. We made arrangements to get Ruth’s 280Z back to ZCG for the new engine rebuild and sorting. The tired L28 would be replaced with a rebuilt, “street-style” 2.8:

 

A few engine details like new injectors, oil pan and MSA exhaust header to replace a cracked exhaust manifold:

   

We replaced all hoses in the engine bay and installed a KOYO race radiator. We wanted Ruth to feel comfortable owning this Z by herself. When everything is in working order on a 280z, they can be just as reliable as any late model car.

ZCG Big-Brakes and CV Axles

It had been a long time since we saw Ruth’s S30 so we replaced the old tires with new Bridgestone S007-a (225/50/16) tires followed by a full alignment. We also installed what we like to add to every Z car built here:  our Z Car Garage Big-Brakes for small wheels. This is an all-wheel, 4-piston caliper kit that works beautifully with the balance of the stock M/C and booster. Keeping things operating smoothly are our 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 Ruth stock brakes and installed our ZCG Big-Brake kit:

   

As mentioned above, the ZCG Big-Brakes work with the factory M/C and booster. We installed a new M/C for Ruth:

 

At the rear, the factory drum brakes were replaced with our ZCG Big-Brakes. Factory handbrake functionality IS retained! We were happy to hear that Ruth,  being an older woman driving her vintage Z car she bought brand new was totally blown-away how well these brakes work!

 

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.

 

Ruth has CV Axle set #332. Stock half shafts (L) and ZCG units:

   

On the road again

 

Icing on the cake after we fixed the Z…following a full detail Rob and Meghan delivered it to Ruth’s home. It was a special moment and Ruth was all smiles.

 

We miss you Larry and this one’s for you…we got Ruth back in her Z car. Know that we will keep this Z on the road while Ruth and ZCG are around! Love cars. Love people. Love life.

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:

At Z Car Garage, the Datsun 510 is very close to our heart. Our hero John Morton piloted a 510 in the Trans Am racing series to put Nissan on the map, fueling every Datsun enthusiast’s passion for hot-rodding the humble economy car. We also have our share of race, personal and project 510s. When Mark G contacted us to work on his 510, we happily obliged especially after learning that it was built by our friend, fellow racer and Datsun 510 guru Troy Ermish.

 

510 Beginnings

 

Mark is an avid car enthusiast, growing up here in the South Bay. His first car was a lowered Capri that he tracked in the 80’s at Laguna Seca. He attributes his 510 passion from its rich racing heritage:

 “I was introduced to Sports Car racing at Laguna Seca in the mid 70’s. I have been going to most all of the different events ever since. My favorite was Sports Cars racing, Camel GT’s, IMSA, ALMS. Thus the ‘Poor Man’s BMW 2002’, my recent 510 is my third and hopefully last. Number 2 was also brought back from the dead and used to commute and cruise over Highway 17 to Aptos to work for my Father’s business. The surf rack was installed to haul all kinds of stuff.”

 

In 2015, Mark decided to fulfill his dream of another 510 and bought a project car:

“I wanted something I could turn into a street racer and autocross car for my son. As in any extensive full blown renovation, everything on the car has been touched. I tore it completely apart, soda-blasted the car, personally sandblasted every bolt and part on the car, welded in new floor panels and rebuilt the trunk, back panel and rear valance.”

The project car:

 

Mark’s extensive bodywork:

 

“I met Troy Ermish early on in the process, so when the floors and trunk were repaired, the car was trailered to Troy for a full roll cage, front fender wells were cut back and jack points installed in the rocker panels at the “B” Pillars.”

 

After 18months of bodywork, which Mark was heavily involved with, it was back to Ermish for the final build out. The car was purchased with a 1600 and funky 4 speed, but Mark also scored a 2000cc with two side draft Mikuni’s and a ZX 5 speed transmission. The engine was sent to Rebello for a full rebuild and upgrade to 2360cc spec.

 

T- Square Brain

 

Mark studied art in school and his attention to detail throughout the 510 impressive. From the no-frills interior to uncluttered engine bay it’s no surprise that he earned the nickname “T-square brain”. Each time I see this car it reveals another level of fanaticism that reminds me how awesome Datsun-owners are. Enjoy a few detail shots with more pics in the gallery below:

Engine Bay

Devoid of unnecessary bits, the Rebello 2.3 with dual-Mikuni’s takes center stage:

 

Interior

 

A tribute to the B-Sedan racing 510s of the 70’s, the interior is spartan with a simple dash, roll cage and OMP seats:

 

Again, it’s super sanitary in here with subtle color choices and straightforward switchgear. That is Pete Brock’s signature on the dash!

  

Body

The 2017 Corvette Racing Yellow paint is loud, but in a good way. Mark’s touches here are an exercise in restraint, while harking back to the Trans Am racers he remembered. The white roundel was inspired by our friend Dave Scholz’ Datsun 240z as seen on Petrolicious . 13″ re-pop’d (VTO) AR Libras are the definitive wheel choice here, with contrasting black spokes and chunky Toyo R888 tires:

 

Sorting at ZCG

 

The 510 was constructed with both Mark’s skillset and Troy’s finishing touches. After he finished his project, Mark visited ZCG for adjustments and sorting.

 

ZCG CV Axles!

 

We upgraded Mark’s standard half shafts to our Z Car Garage CV Axles. These CV axles help transmit power to the ground and ensure smoother operation compared to standard half shafts, while eliminating the need for aluminum adapters.  Mark got ZCG VV Axle set #320 and he loves them:

 

Nick about to install the new CVs:

 

Standard half shafts (left) and ZCG CV Axles (right). Note all of the powdercoated suspension parts:

   

Getting Mark Back On The Road

 

Mark was experiencing a re-occurring high water temp issue. Finally the head gasket was compromised so we pulled the engine for a refresh.

 

We re-intalled the the engine and tidied up the engine bay. The electric fan was removed and a fan clutch installed utilizing a 620 water pump/S30 fan blade to make it all fit behind the Koyo radiator:

 

Dyno Tuning

On the dyno, we had a case of deja vu as Mark’s 510 is almost similar to Keith’s. Rob is familiar with tuning the L-Ser-es engine in both race and street 510s. Mark’s Rebello 2360 put own 189hp/178tq to the wheels, gaining 8hp/10tq with Rob’s tuning. You can hear it scream in the video below. Mark will re-visit us for another dyno session after he accumulates more miles.

 

Enjoying The Ride

 

With a few more minor tweaks like door locks and windows, Mark was out and about with his 510. He joined us at the local Fuel Supply Cars and Coffee:

 

Enjoy this video of Mark’s 510 in action:

 

We even spotted Mark at Driving While Awesome Morning Motors:

 

 

Do It In A Datsun

 

I was fortunate to catch up with Mark and meet his son Dom who also has motorsports background. It was rad to see the Datsun being a family affair and Mark all smiles behind the wheel:

 

 “I feel very lucky to be part of the Z Car Garage family. The staff are  all great guys. I will continue to bring the car in for Anything it needs.”

 

Big thanks to Mark for letting us service his 510. We really enjoyed having the 510 in the shop!

 

Speaking of Love for The 510…this weekend 20+ B-Sedan racers will be running at Laguna Seca. I will have a full report for you, stay tuned!

When we learned that a Nissan Silvia was in our area Z Car Garage got excited. This is not the 90’s Silvia (Nissan 240sx here) we know and love, it is the ultra-rare 1965 Silvia CSP311. Only 554 examples were made from ’67 -’67 and never imported to the US.

 

Fortunately for owner Rick K, he was able to acquire this Silvia from our friends at JDM Legends:

“My son (Matt) and I were searching for a nice 240Z. Throughout our search, Matt kept telling me about the Silvia (CSP311).  One became available through JDM Legends. I just wasn’t sure about it until we saw Myron Vernis’ beautiful Silvia featured in a recent JDM exhibit at the Peterson. When we saw the car in person, we were hooked. We purchased the Silvia from JDM-L. It is built on the Nissan/Datsun Roadster chassis and drive train, so it is fun to drive and reliable.”

The Luxurious Datsun 1600 Coupe

 

The Silvia is special for many reasons. As Rick mentioned above, this car was built on the Datsun Roadster chassis, meaning it is a body-on-frame platform sharing the same R16 drivetrain as the Datsun 1600 (SP311). All were hand built and right hand drive with a gorgeous interior. Fairlady owners will notice familiar gauges and switchgear–all borrowed from the contemporary Datsun Roadster. The body was designed by Kazuo Kimura with influence from Albrecht Goertz (of 240z/2000GT fame):

 

Although it was a beautiful, robust little coupe it was not a sales success for Nissan. It did however pave the way for the larger S30:

“Nissan shipped one to the fledgling Datsun distributor in the US. They did not think it would sell in the US (re-naming it a Datsun 1600 Coupe) and that was the end of CSP311. It never made it to full production. We believe ours is one of 5 currently in the US.  Most are in Japan with a large group in Australia as well.  We guesstimate that there may be 150 still in existence world wide.”

 

The Silvia at Z Car Garage

 

Rick brought the Silvia in to us for an inspection and to ensure it was road-worthy. We thank owner Eric Bizek of JDM Legends for referring Rick to us!

“Eric at JDM told us about Z Car Garage and Rob.  Knowing that one of the best shops in the country was 10 minutes from our house gave us the confidence we needed to buy the car.  We knew we had a great shop to work on it in the Bay Area.”

We developed a plan to address some deferred maintenance and sort out the tired suspension. A surprisingly clean underbody (remember this came from Japan!) revealed some corrosion:

 

To satisfy our curiosity we placed the Silvia on the scales and it checked in at a scant 2210lbs:

 

We even put it on the dyno to make sure the engine was healthy. Could this be the only Silvia in the US to be dyno tuned? 😀

 

The Silvia put down a stout 67hp/81tq to the wheels, enjoy the video:

 

 

Rick and son Mat have been enjoying the Silvia and sharing it with other enthusiasts.

 “Matt and I enjoy driving it often. We also have taken it to Cars and Coffee events in the Bay Area and most notably were welcomed with position A at the Wrigley building in Santa Cruz. The Driving While Awesome Cars and Coffee was one of the best we had been to.”

We also spotted it at the 2019 Saratoga Classic Car Show:

 

While Rick and Matt were at the shop we let them drive Butters, our  1970 Series 1 shop demo Z. They were hooked:

“Hi Rob,  It was great to meet you and your team.  Matthew could barely sleep last night after driving Butters.  Thanks so much for letting us take it out.  Truly amazing. We want a Z just like that.”

 

Big thanks to Rick for letting us work on the Silvia. We suggested that a car this rare and significant should be as close as possible to a factory correct restoration which we agree with. For now they are just Enjoying The Ride!

 

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!
