Since Nissan lent us the 2023 Z to enjoy during Monterey Car Week we have been attending events and sharing the Z with fellow enthusiasts. On 8/17 we started with the Motorlux kick-off celebration (formerly McCall’s Motorworks Revival). On Friday and Saturday we attended the Rolex Monterey Motorsports Reunion at Laguna Seca. Finally on Sunday we closed with a visit to the Pebble Beach Concours d’Elegance. Enjoy our report with photos video from Car Week in the new Z!

 

Vintage Racing at Laguna Seca

 

We love vintage racing and had a blast at this year’s Rolex Monterey Motorsports Reunion. On Friday we parked the new Z in Row C of the paddock with our friends from Racecraft. Race car driver and restoration specialist Jim Froula piloted the Greg Alderman 300ZX and a Nissan 240SX, both in IMSA trim. The Z31 features our ZCG CV Axles:

 

The new Z was well-received at the race track. We showed people around the car and let them check it out, always happy to share with enthusiasts! Many people shared their love for the Z and posted photos on social media (thank you!). Below L to R: Larry Oka displaying Gary Cooks’ Z, Rob showing the new Z in Racecraft paddock and Meghan Fuller with the legend Pete Brock:

 

Hanging out with the Breakfast Club

 

Before heading to the track on Saturday, just before the races we joined the Breakfast Club Rally at their pre-rally gathering in Carmel. The BCR organizers kindly gave us a spot to park the new Z during their social hour from 8-9am prior to the event start. It was a great time chatting with new and familiar enthusiasts. We loved seeing our client Jay W with family creating memories in his Datsun 510 featuring our Z Car Garage CV Axles:

 

BCR’s rallies always bring a variety of vintage and modern metal, more photos in the gallery below and don’t forget to join us for Breakfast Club’s upcoming Tokyo Calling2 event 9/24!

 

From Carmel we headed back to Laguna Seca with the new Z for even more racing action. It is worth noting the complete absence of any vintage Z cars Datsun 510s on track at this year’s reunion. Have no fear as the upcoming Velocity Invitational will have a dedicated B-Sedan race group and many Z cars racing! Despite the lack of Datsuns on track we enjoyed the Trans Am and other feature race groups.

 

We left RMMR happy and ready for more Monterey Car Week fun. As if we did not receive enough attention in the paddock, Rob and Meghan were flagged down by CHP– only to inquire about the new Z 🙂

 

Pebble Beach Concours

 

A spectacular ending to Monterey Car Week was Sunday’s visit to the 71st Pebble Beach Concours d’Elegance. Rob and I drove the Z one last time back to Monterey and spotted our friend Tony on the road in his mint 13B-powered Mazda RX-2. Arriving in Pebble Beach, event parking along the famous 17-Mile Drive was a car show itself with cool cars lining the shore:

    

We were bussed into Concours Village and immediately greeted by the Japanese Automotive Invitational(JAI):

 

This display showcased 17 historically significant Japanese cars within several categories including: Concept Cars, “Kei” and Small Cars, Luxury Sedans, Sports Cars, Coupes/Hatchbacks, and Trucks/Utilities. Z Car Garage was proud to support and help prepare the iconic 2003 Infiniti FX45, owned by former INFINITI designer, Julien Thiebaud:

 

Our friend Sean Morris and his team at Toprank International Vehicle Importers showed two stunning Nissan Skylines: an R34 GT-R in rare Midnight Purple II (above) and Kenmeri C110 GT-R:

 

Daniel Song’s Datsun 240Z built by JDM Legends, a “Hakosuka” Skyline and Jun Imai ‘s (of Hot Wheels fame) Datsun 510 Wagon. As with previous JAI displays this was free and open to the general public, more photos in the gallery below!

 

From the JAI we walked past the Concours Village and entered the ticketed, official Pebble Beach Concours….or so I thought. Here, Mercedes Benz had their own display and so did Ferrari. Apparently this was “just a taste” of what lie ahead!

Ferrari display:

 

Mercedes display:

 

The Concept Lawn in front of the lodge was barely visible due to the crowds of photographers and admirers trying to get eyes on the latest dream machines from Koenigsegg, Genesis, Hennessey and Guntherwerks. Lincoln’s new L100 Concept stood out as did Czinger’s 21C hypercar.

 

The Lawn at Pebble Beach

 

The competition field awaited us and I was not prepared for what lie beyond the Lodge…over 200 automotive treasures lined the 17th and 18th holes of the famed Pebble Beach Golf Links. Nestled amid prewar classics were Alfa Romeos, Aston Martins, Packards, and Duesenbergs. We were among well-heeled car enthusiasts sharing similar interests in admiring ornate sculpted hood ornaments, gleaming art deco designs and distressed leather seats.

 

Making this experience even better were our longtime friends Jan Trondsen and Dave Sholz. In addition to being die-hard car enthusiasts and Datsun owners, they are both seasoned Pebble Beach attendees and gave us the royal tour. With MOET in hand, we embarked on a journey back in time to admire metal, leather and artistry. The 100th anniversary of the 24 Hours of Le Mans was celebrated this year at Pebble. Our favorites included the 1979 Porsche 935 K3 Coupe and 1962 Ferrari 250 GTO Scaglietti Berlinetta:

 

Many attendees at the Pebble Beach concours dressed like it was the Kentucky Derby of motorsport.  Party-style suits and dresses, bright colors, and feather-clad hats brightened the lawn during the morning fog along the bay. We had several celebrity sightings including Chip Foose, Wayne Carini and ex-Formula One driver David Coulthard!

 

The judging process at the Pebble Beach Concours d’Elegance has two parts: Class Judges focus on originality and authenticity, while Honorary Judges focus on attention to design, styling and elegance. Dave pointed out that none of the cars we saw are allowed to participate the following year…

 

This Duesenberg caught my attention as the judges scrutinized it. I was able to capture video of the straight-8 engine firing up as well it was beyond impressive:

 

Enjoy this video showing our time at the Rolex Monterey Motorsports Reunion and Pebble Beach Concours!

 

After a few intense hours of geeking-out on the cars we took a break for a meal. Huge thanks to Infiniti and Jul Thiebaud for hosting us!

 

So who was the Best of Show winner? That fabulous 1932 Duesenberg Model J that I captured being scrutinized by the judges!  To be eligible to win Best of Show which is the event’s highest award a car must first win its class. What a machine!

 

With the show concluding we parted with our friends Jan and Dave. Rob and I headed home in the new Z. The bus ride back to the Z was again another car show along the 17-Mile Drive. We spotted an R34 Skyline GT-R and Z31:

   

 

Thank You!

 

We can’t thank Nissan and Infiniti enough for the opportunity to share the new Z and enjoy Monterey Car Week. Stay tuned for dyno testing, in-car and exhaust video for this 9-speed automatic Performance model. Enjoy the photo gallery below and Long Live The Z!

Dear Zcarblog readers, it’s been a busy year and we are catching up on blog posts, so please enjoy our belated race report from April.

WE LOVE RACING! On April 1-3, Classic Sports Racing Group (CSRG) hosted the David Love Vintage races at Sonoma Raceway. Z Car Garage had a blast racing and supporting several client’s Datsun 510 race cars running in B-Sedan Group 9 (John Morton Cup). It was a great weekend filled with competition, camaraderie and plenty of Alfas, BMWs and Datsuns sharing the track. Enjoy our report with in-car footage and photos.

 

Z Car Garage Supports Three Datsun 510s

It is our pleasure to bring more enthusiasts into the world of vintage racing. Our services do include full race support and car-preparation to help make client’s race days seamless and worry-free so they can focus on driving. One of our specialties is dyno tuning. Before a race weekend we confirm that your car is running well and make necessary adjustments while on the chassis dyno.

Video of two Datsun 510 B-Sedans (Rob and Tom), Enjoy the sweet L-series music!

ZCG clients running at the David Love Vintage races included:

#7 Kelvin

Kelvin’s 510 features our Z Car Garage CV Axles and dyno tuning. He achieved a personal best lap time at Sonoma:

   

#71 Ed M

 

Ed is friends with Kelvin and started joining Z Car Garage last year. He also achieved a personal best lap time at Sonoma.

 

#7 Rob Fuller

 

Rob Fuller piloted the Bay Area Datsun Dealers tribute 510. Here is his report from the race weekend with in-car video:

“First CSRG race of the season and our favorite events to go to with a relaxed atmosphere and super cool people. This is one of the oldest vintage racing groups in the US and we love watching the B-sedan group grow. As we continue to report on these events it makes u happy to see more and folks racing and spectating. We want this sport to grow and be alive for the next generation of enthusiasts and drivers!”

 

“We headed to Sonoma Raceway, missing our buddy Tom Dockery in his Ex-Norm Balzer 510. It was involved in an incident on test day preparing for the event and will return soon. It was a superb race weekend for myself, Kelvin and Ed. We were cutting it up with Troy Ermish and Parker McKean (son of Bruce from PNW) in his fast Alfa.”

“Our buddy Josh Moriarty in his 510 had engine failure so Dave Rebello made a guest appearance visiting the track. We installed Rob’s back up engine into Josh’ 510 and he was able to finish the race weekend…that’s the spirit of vintage racing. We are all there to support each other and have a good time. Sure, it’s fun to be competitive but at the end of the day it’s more important to spend time with friends and family. It was a great weekend.”

 

Enjoy this in-car video from Rob’s 510 chasing Parker and Troy:

On Sunday 7/31 we attended the Morning Motors Cars & Coffee event hosted by DrivingWhileAwesome (DWA) in Santa Cruz, CA. The event impressed us again with a fun vibe and superb variety of cars. One of the many perks of DWA Morning Motors is its location surrounded by the best driving roads.

 

This morning’s pre-event gathering met at Alice’s restaurant at 8am. Our group started with 4 cars including Rob (Porsche 993 Turbo), Josh (VW bug), Kurt (Subaru 2.5RS) and myself in the Z Car Garage 1967 Datsun 2000:Our brisk run up HWY 9 was amazingly traffic-free and plenty of room to enjoy the twisty bits. A brief pause at the 9/35 junction to meet Nick in his Datsun 510 Wagon:

 

We joined our friend Naveed (thanks for organizing!) and few other enthusiasts at Alice’s. Below, Mark’s 1971 Datsun 510 and Erich’s1974 Alfa GTV give off B-Sedan vibes in the am light:

 

After re-connecting with friends we headed to the Santa Cruz via 84 and HWY1. The lot in front of the Old Wrigley building was near full a few minutes after 9am.!

   

Mandatory Nissan/Datsun

I was happy to see so many Nissans and Datsuns at Morning Motors.

 

It was a real pleasure to see Rick’s 1965 Nissan Silvia, driven by his son Matthew!I had a blast driving this RHD gem on the strongBreakfast Club Rally back in March:

 

This R33 Skyline GT-R was recently acquired by DWA co-founder Art C our friends at Toprank International Vehicle Importers. Super stoked for Art and glad to see him enjoying it! Love the BBS LMs!

 

 

Datsun B210!

 

There were several S13/S14 240SX sports cars, G35s and a Z33 on WORK T7R 2P wheels:

  

Another ZCG client, Eric’s Infiniti FX35 sporting upgraded suspension and R35 GT-R wheels. Parking next a mint 2003 FX!

  

In Search of J-Tin

Morning Motors did not disappoint if you are Japanese Classic fans. Representing Mazda was our friend Tony’s 13B-powered RX-2 and his Rotary gang:

   

90’s icons…Third gen (A70) Supra and FD RX-7 (on ADVAN wheels)!

  So much variety! Enjoy this short video:

Euro Classics

Yearning for Porsche’s? Or something a bit less “mainstream”? DWA CnC did not disappoint. Citroen 2CV:

 

Porsche, Alfa and Austin Healey

   

Lone E38 7-Series BMW…peak 7 in my mind!

 

My favorite car was this Porsche 914-6:

 

American Muscle

From 60’s to 80’s. Mike Garret’s familiar purple Mopar with late-model drivetrain and really wild Ford Coupe with diesel engine:

 

DWA CnC is definitely my kind of cars and coffee. It’s a great venue with amazing driving roads nearby and the cars were so diverse. We highly recommend checking it out! Thanks to the DWA crew for hosting. If you haven’t already, listen to their podcast and make sure you give them a follow on Instagram.

We have the pleasure of continually developing Dirk’s 1973 Datsun 240z to help achieve his vision of a Z car that is adept on the street and track. Improving the driving experience are our Z Car Garage Big-Brakes, Z Car Garage CV Axles, Silvia 6-speed transmission and a host of chassis and driveline upgrades.

 

Dirk shares his experience working with us:

“Collaborating closely with Rob and ZCG has elevated the optimization process. Rob will frequently talk me out of a bad idea, or into a good one (like the OS Giken LSD). Sometimes I talk him into a bad idea and it turns out to work really well, like the S15 gearbox. The most fun is when we brainstorm stuff together like turning the catch can setup into an improvised simple PCV system, eliminating all hints of oil fumes from the car while running.”

Datsun 510, 620 and Z car love

Since our last iteration, Dirk as been back to Z Car Garage for a few major projects. Let’s take a look at his Datsun story first. Dirk bought his first Datsun in 2014, a 1970 510, to learn how to work on cars himself. After learning more about the history of Datsun, and the significance of both the 510 and the 240Z in establishing Japanese cars in the American market, he knew he had to own a Z as well.

  

A year later, the right Z showed up on eBay in Texas, a 1973 in silver gray. After pouring over the photos and talking to the seller, Dirk bought the car sight unseen. The idea was to have a nice Z to enjoy and drive, while continuing to work on the (sometimes not) rolling restoration of his 510. The car was lovingly restored by a dad and his children and in mostly stock condition. Dirk also has Datsun 620 work truck complete with dual-Mikuni’s:

  After many more tweaks, different induction setups, spring rate changes, rebuilt stock brakes, and 24K miles of driving including a few track days, Dirk’s Z was inching closer and closer to his vision.

 Photos: Dito Milian/Gotbluemilk.com 

“After installing a Datsun Spirit STR-3 engine with a set of Nismo Mikuni PHH44 carburetors, the biggest weak spots left were the rest of the drivetrain (especially the stock 4-speed transmission, but the Subaru diff had also developed some bearing issues), the stock brakes, and of course the loose nut behind the wheel – but sadly that last component typically takes too much money and time to modify thoroughly.”

  

After comparing the Z to his Subaru BRZ on the track, it was clear the Z was better at everything except for shifting gears. Since his engine made a healthy amount of torque, but not enough to warrant a CD009 (350z) transmission, Dirk kept looking for alternatives. He also wanted something with slightly closer gear ratios to better suit the engine’s power band. An S15 Silvia 6-speed seemed like the perfect fit and we installed it back in 2019.

S15 6-speed transmission

  

The first S15 box had some weak synchros, so Dirk sourced another one that was installed with OE trans fluid, as well as a set of fresh OE motor and trans mounts to help with shifter feel and reduce vibrations in the car.

“The S15 transmission fit surprisingly well. ZCG built a custom crossmember to locate it, and the shifter lined up almost perfectly. No transmission tunnel mods were necessary. The modern shifter looked out of place, so ZCG built a custom unit that would look stock, and work with the Datsun competition shift knob. A small 6-speed shift pattern sticker modeled after the one used in the Silvia is the only clue there’s something different going on under this car. And of course the driving experience.”

Making the S15 shifter look factory, we are happy with the result and Dirk’s subtle shift pattern sticker:

   

The Datsun Comp shift knob complements the steering wheel:

 

Chassis and Driveline Upgrades

First, there was work to upgrade the steering geometry and suspension. With the car being lowered quite a bit, despite having 1″ RCAs installed, it had a ton of bump steer. Rob installed DP racing adjustable tie rods, removed the front springs, and completely eliminated the bump steer on the alignment rack while moving the suspension through its full range of motion.

New DP Racing tie-rods and in-house alignment:

 

We also refurbished Dirk’s steering rack with fresh parts from our stash:

 

With the Z back in the shop for bodywork we took the opportunity to make more suspension changes. New Koni Race shocks from T3 were installed, which were a much better match for the 300# and 350# spring rates than the Koni Sport shocks they replaced (as Dirk initially ordered the coil overs with lower spring rates, he never replaced the shocks after adjusting the spring rates, and the car always felt underdamped, particularly on the not-adjustable compression stroke):

 

ZCG Big-Brakes and CV Axles

    Dirk visited ZCG and drove “Mrs. Butters”, our 1970 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 🙂 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 Dirk’s stock brakes and installed our ZCG Big-Brake kit.

 ZCG Big-brakes replacing stock setup up front:

   

At the rear, the factory drum brakes were replaced with our ZCG Big-Brakes. Factory handbrake functionality 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 70 CV axle kits on customer cars and we are stoked with all of the positive feedback.

  

Also visible on Dirk’s Z are the excellent adjustable lower control arms from Techno Toy Tuning.

  

3 Liter L-Series Power

Unfortunately, the Datsun Spirit engine developed rod knock which was the impetus for a big drivetrain upgrade. Several other parts of the car where refined as well.

 

The L28 engine was pulled, sent to Rebello, and built into a 3L powerhouse. Dave bored out the 44PHH venturis to a custom 38.5mm, to hit the perfect compromise between peak power and drivability. We also installed a fresh water pump, alternator, new fan blade, OEM fan clutch and fresh air filters. The beautiful DP Racing oil pan remained. More photos in the gallery below:

 A custom stainless 2.5″ mandrel-bent exhaust mates with a new set of coated Pacesetter headers and Z Story Street muffler (in a search for a reduction in volume while keeping a nice note). Dirk discusses the clutch/flywheel combo below:

 

“The STR-3 already was able to slip the Exedy clutch and we were never fans of the Chromoly steel flywheel. A Jim Wolf Technologies clutch and flywheel combo was installed after first trying a newly developed Kameari single plate street clutch kit, which we both found too loud and racy for this street car. While the JWT pressure plate yielded a different pedal feel that took some getting used too, it was not too heavy and perfectly comfortable to drive in traffic. More importantly, it never slipped under any kind of abuse.”

The clutch hydraulics were replaced to work with new alumimum flywheel/JWT HD clutch combo:

  

We installed a ZCG-built 4.11 OS Giken limited-slip differential in the R180 along with a custom aluminum driveshaft:

   

Dyno Tuning

 

The previous L28 made 202hp/194tq at the wheels with Rob’s tuning. Now with the fresh 3L it baselined at 245hp/226tq with more area under the curve:

 

Rob tuned the car further on the chassis dyno, setting it up with a very lean idle at Dirk’s request (to minimize gasoline fumes at idle). With A/F optimized and Nismo Mikuni carbs massaged, Rob unlocked another 20hp yielding a stout 265hp/232tq to the wheels:

  

With gains of 62hp/37tq at the wheels over the L28, Dirk is very happy with the new 3L:

“While the Datsun Spirit engine had a very peppy mid-range and made more delicious induction noises, there’s no argument that the more powerful Rebello engine elevated the car to the next level of performance and fun. The entire setup worked incredibly well together, and we hit an impressive 265hp at the rear wheels, or 60hp more than the engine made in its previous iteration, putting it in the 100hp/liter ballpark at the crank. Not bad for a dinosaur engine on California pump gas!”

Enjoy the dyno video and L-series music!

 

Sorting

The little things are what we excel at and Dirk had a list for us to knock out. While at ZCG, we replaced the heavily sandblasted OE windshield, and did some rust remediation in the cowl area, as Dirk had started noticing water making it into the interior fan assembly after washing the car. More photos in the gallery below:

  

The heater and blower motor assembly was refurbished with new ducting seals and lubed linkage:

 

The headlight switch had also developed some issues where sometimes the lights would turn off completely when switching between low and high beam, and was replaced with a good used example from the ZCG parts stash.

“The headlights now worked reliably, the new engine didn’t consume any significant amount of oil, and the whole drivetrain worked together even better than before with the new clutch and flywheel combo.”

 

Unfortunately, 7 months and many miles later, Dirk was back after a minor nighttime crash that took out the left fender, front bumper and valance, and dented the hood. After bodywork and paint from our man William from William’s Auto Body, we installed a euro front bumper, used turn signal assembly, cleaned up electrical wiring from alternator through firewall and sorted his Speedhut GPS speedo box.

  

To improve safety, comfort, and avoid future crashes, Dirk upgraded his headlights to a new set of Holley Retrobrights, and GTR Carbide 2.0 turn signal bulbs front and rear from Headlight Revolution.

“The headlights are a world ahead of the old Maxxima LED units, which themselves outperformed the Sylvania Halogen sealed beams, while staying very under the radar, with their sealed beam-inspired looks. And the turn signals are now highly noticeable, even in the brightest daylight.”

 

Enjoying the Ride

Dirk’s been driving his Z-car pretty much every day since the latest upgrades, and it’s been working phenomenally well:

“The drivetrain + brakes make it as happy to accelerate as it is to stop, and with the quick, closely spaced shifts and eager engine, it’s fun to do a casual grocery run, and to drive quickly. With the electrical systems and all fumes well under control, it’s truly a car you can do anything with, and probably more reliable than my BMW.”

 

We loved to see Dirk driving his Z on rallies and fun runs this year. Most recently we joined fellow Japanese vintage car owners on the Tokyo Calling event hosted by Breakfast Club Rally:

 

Dirk also joined us for a New Year’s Day drive through our favorite Bay Area Backroads:

 

We enjoyed working with you Dirk and it was rewarding to help improve your Z.

“Some say good is the enemy of great, but that’s true if you think you’re done. I don’t see my Z car less as a “build” that’s done. I’m always developing it, just like continually developing a race car (e.g. my Lemons car, http://instagram.com/bittersc243) to stay competitive. In this case the competition is merely for making the Z into the most fun driving experience I can imagine, and the journey of continuous refinement and improvement is a big part of the fun for me.”

 

While Dirk works through a few interior projects (new carpets, stereo upgrade) on his own, we’re getting ready to further revise the front suspension/steering, and wider wheel + tire options. Enjoy more photo documentation of our work in the gallery below. Thanks for your support Dirk and LONG LIVE THE Z!
