At Z Car Garage we love keeping Z’s on the road. From concours-level restorations to light refurbishments, making a client’s goals reality is our passion. Richard W brought his 1971 Datsun 240Z from Eureka, Ca for a full mechanical restoration, ZCG-style. Our Z Car Garage Big-Brakes, Z Car Garage CV Axles and Z Car Garage Heat Shield along with a new drivetrain and full suspension transformed this Series 1 S30.
In 2017 Richard contacted us to inquire about restoration work. He understood we were booked, and we spoke again later, but this time he visited the shop with a photo album filled with photos of his beautiful, Sunshine Yellow Z.
“I did my due diligence and researched what ZCG could do, and arranged for a meeting with Rob to discuss my car. I asked if he would be interested in restoring my 1970 240 Z. He was pretty adamant, ‘I don’t restore those rust buckets anymore.’ A little disheartened but I persisted. Would you take a look at the album I have of my car? He flipped through he pages and you could see him light up and the enthusiasm came forth. He said, ‘Where is the rust?’. I told him there was none as the car has been indoors for the last 40 years.”
Rob and Richard agreed that since the exterior was in great shape ZCG would perform a mechanical restoration. Richard is in his 70’s and still practices dentistry in the small town of Eureka. After being parked for decades he trailered the Z down and arrived at ZCG in January 2018 . Here is VIN #12291, with 63k original miles:
He bought this Z brand new 12/70 and absolutely adores it, being an integral part of his life for half a century! We love the story behind Richard’s Z lets’ take a look before going into the mechanical work…
Life With The Z
“We all have defining moments in our lives and those moments need to be prioritized. The marriage to my wife of 50+ years is of course the most important moment. She provided the resources to live in San Francisco and was so supportive of my graduation from college. That same year she became pregnant with our first born. We moved to Eureka at the same time. I was able to start my own business in 1970 and begin an adult life. All the important hurdles were checked off. We moved to Eureka with $300 in our pocket and a mountain of debt. But wait, there was one more hurdle…”
“…From across a parking lot, in Eureka no less, stood a bright yellow Ferrari. Upon closer inspection I was even more baffled. What was a Datsun 240Z? I went to the local Datsun agency, long before Nissan came along and made my inquiry. Yes, the new 240Zs are very special and very desirable. They were being shipped in but there is a waiting list. Just add my name. Sure enough they called a few weeks later and said there was an Orange Z on the lot. They made the mistake of letting me wring that car out and I was sold. While I was in school in San Francisco, I saw Cobras and Porsches that cost $6 – $7,000. Way out of my league but I could afford the $3,600 Z. Even if it meant borrowing $1,200. In early December 1970 I took possession of my Z. It became my car and my identity. It has remained just that for the last 50 years.“
“My oldest son was born the following February. Now all the pieces for my life fell into place. Marriage, college, moving to a permanent home, birth of our son and the final piece, my sports car. Being a young family in the ‘70s was simple. We just put Jason between our two seats the Bull Dog in the back and off we drove. No thought of a car seat. Before he was six months old, we had been the 700 miles to San Diego and the 700 miles to Canada. Not a care in the world and a wonderful way to see the country.”
“My car was a daily driver. For the next 20 + years that was my car. As my boys grew up and learned to drive, I needed to provide a car for them for high school. Well, not my car. So, I bought them an upgraded and modified ’71 240Z. I bought the Z because I felt they would be safer in that car. I didn’t want a larger car they would put a lot of friends in. Later on, I heard they actually had put 5 guys in the Z car.”
Of course, over time, tastes changed and Richard succumbed to buying a 1992 Corvette. You know, the ones you fall into and climb out of. Fast forward to 2015 and his 240Z is in the garage, covered with the things a guy collects in a garage. The ‘vette became useless and the family all preferred the Z. This is where ZCG becomes part of Richard’s Z car journey. Let the mechanical restoration begin on this Series 1 that has not run since 1985…
Drivetrain
We got the original L24 with SUs running after sitting for years, but Richard wanted more power and Rob suggested a Rebello 3.1L engine. Supporting parts included an MSA 6-into-1 header, ZCG exhaust system, internally regulated 280ZX alternator, 280ZX gear reduction starter, KOYO race radiator (custom upper hose) and Z Car Garage Heat Shield. Here are a few pictures of the engine build/installation with many more in the gallery:
Powdercoated and plated parts adorn the engine:
Induction is handled by triple-Mikuni PH44 carbs on a Harada intake manifold.
Beneath the triple-Mikunis is our Z Car Garage Heat Shield, serial #00250:
To handle the power from the 3.1L engine we replaced the stock transmission with a Nissan KA24 (FS5W71C) transmission. This was a common swap (before the CD009a came to market) performed by modifying a 280Z L-series bell housing. The KA24 unit is significantly stronger than early S30 transmissions.
Engine Bay Services
Richard’s Z received a total engine bay restoration. Please visit the gallery below for more pictures documenting the engine bay restoration work, it’s where our efforts shine!
With the engine/transmission removed we focused our efforts on restoring the engine bay. Everything was cad plated or powdercoated. All new fuel hoses, every cooling hose and all new hydraulic lines. Every nut/bolt is bagged and tagged before re-plating.
The Z’s body had been painted once before but the engine bay was left un-touched. We called upon our man William from William’s Auto Body re-spray the 919 Sunshine Yellow and it turned out fantastic. Before/After:
With the new engine/transmission even more detail work was performed:
Final Before/After in the engine bay:
Our ZCG Exhaust system using 2.5″ piping to a stainless resonator and Magnaflow muffler with slash-cut tip. Listen to the sound in the video below!
Dyno Tuning
Rob dyno tuned the Rebello 3.1L engine making a stout 199hp/221tq to the wheels. Enjoy the L-series music in this extended video of Richard’s Z including dyno runs, test drive with Rob and drive-bys:
Suspension
Richard’s chassis was treated to a full suspension rebuild with new parts, bushings and a full coil-over (Koni struts with our spring rates) 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.
New parts included the T3 adjustable T/C rods, T3 rear control arms, T3 front/rear strut tower bars, new ball joints, new front bushings, all new bearings and seals and ST sway bars. Richard 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:

Rear end with T3 lower control arms and ST Sway bar:
ZCG Big-Brakes and CV Axles
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 went ahead and got Richard dialed in with the ZCG big-brake kit for small wheels with parking brake and a new OEM Nissan master cylinder. More pics in the gallery!
Front brake installation:
At the rear, the OEM drums brakes were replaced with our ZCG Big-Brakes. Factory handbrake functionality IS retained!
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 130+ CV axle kits on customer cars and we are stoked with all of the positive feedback.
Richard’s standard half-shafts shown on left:
Panasport Wheels
Our ZCG Big-Brakes also look great behind Panasport wheels in our offset allowing us to run 225/50/16 tires (Bridgestone S-007a). The Z was fully aligned afterwards.
Interior
One of our favorite upgrades to the interior of an S30 is our ZCG sound deadening package. Usually found in our full-blown ZCG restorations, the result is a less tinny sound and almost Germanic-like “clunk” when you shut the doors.
We are really proud of the HVAC system in this Z. A vintage A/C unit was modified to work with the factory heater box and OEM controls. Our client Kurt W 3D-printed us a vent part to allow the A/C to blow cold and hard…see the video! We are working on a solution for all our customers stay tuned!
New, high-end carpet throughout:
The stock seats were replaced with Recaro Specialist in black leather, we love these seats for the S30:
Details
The little things are what we excel at. Exterior items include straightening and re-chroming both f/r bumpers. We also removed the 80’s style front spoiler and replaced it with the the correct 3-piece setup from our Series 1 parts stash:
Please check the gallery below for more detail shots, there are too many to list in this blog post!
Enjoying The Ride
In December 2020 Richard made the trek from Eureka down to Z Car Garage to pick up his restored Z. After he came back from his test drive it was quite emotional for the two Z car enthusiasts. Rob recalls…
“Richard got out of the Z and told me he had bought this Z 50 years ago that week, it’s been with him through alot of stuff and now his kids and grandkids will get to enjoy it. I looked him in the eye and said I’ll be here for their chapters, any time they need me. I’m attached to this Z now too.”
Richard was ecstatic. It was the reaction we live for at ZCG:
“I delivered the car to Rob and put a lot of trust in him. Nothing happens fast but what happened to my car is truly miraculous. Rob’s attention to detail is unsurpassed. It was just last December that I was able to pick up the car. It was exactly 50 years to the day that I bought the original car. It is not the Z car of yore. Rob had replaced everything. If it was bolted to the frame, all the original equipment came out. From new Recaro seats, interior upholstery replacement and sound deadening. He started up front with the radiator through new larger engine with 3 -2 barrel carburetors to tranny, exhaust system, suspension tires and wheels. It is a brand new car inside but still looks like the Ferrari I saw so many years ago.”
Richard began Enjoying the Ride in his fresh Sunshine Yellow Z back home. He sent us an e-mail of his adventures.
“It has been a whirlwind 4 days in my life. Friday was my drive to San Jose hauling a trailer and all the while the anticipation of seeing the Z after the restoration. Saturday morning was nothing short of exhilarating. There was my little beauty, long in tooth but brought back to its original radiance. Not just radiance but purposeful modifications. What you have done with the car is truly remarkable. It is not the same car beneath that unmistakable glow.
Our visit and talk was also a highlight for me. Your exuberance is contagious. I do so love out of association. You have given me a link to my past and the wonderful times I have spent with Cheryl and my boys. So ends an odyssey that began a few years ago. I could not be happier for two reason. My car has been brought back for me to enjoy and I have made friends with an amazing man. Thank you Rob for all you have done for me.”
Richard, thank you for letting us be part of your Z car journey. We love your passion and connection to your Z. Enjoy the photo gallery and…
