Classic Sports Racing Group (CSRG) hosted the Sears Point Challenge at Sonoma 10/3 and Finale event at Thunderhill 11/1.  Z Car Garage participated  in both events, supporting several client’s Datsun 510 race cars running in B-Sedan Group. Great weekends filled with competition, camaraderie and plenty of Alfas, BMWs and Datsuns sharing the track. Enjoy our race reports with photos and video!

 

Sears Point Challenge 10/3-5

 

ROB: Beautiful weekend at historic Sonoma Raceway (which will always be Sears Point to me). We had a a few bitchin’ 510s including Tom Dockery and Kenny. Super excited to test out the suspension fresh and adjustments on Noah’s Bluebird coupe.

 

Everything seem to be working well with Tom, Kenny everyone up to a really good pace, it was fun.

 

Lots of cool hardware in the paddock:

Vintage Spec Miata

 

ROB: The Classic Sports Racing Group (CSRG) is excited to welcome Vintage Spec Miata (1990-1997) to all of their events! This is a fun, affordable way to get into vintage racing. Each event we see more really clean VSPs coming out to race. Season high for us in Sonoma, with I believe 10+ cars out there:

 

Speaking of glorious…we would like to introduce you to “Little Butters”, our 1991 Vintage Spec Miata that will be available for rental throughout the vintage race season. Contact Rob at ZCG for details. Since this is a new build for I drove it for the weekend to make sure it was sorted and ready to rock for any client that wants to enjoy it. It has a competitive race engine, Penske shocks which are the current suspension for SCCA Spec-Miatas. Just to pay tribute to how wonderful Mrs. Butters Z (our Series 1 shop 240z) is,  we painted it Safari Gold. It’s nickname is Little Butters,  Josh likes to call it “I can’t believe it’s not Butters” and then we picked the number 23 because we are Nissan dorks.

 

Anyway it was fantastic to have the car out and then honorable mentions are Lora B, she keeps kicking ass in her Spec Miata and Allison as well. Also on Saturday and Sunday we had Ross Lindell in the Randy Pobst National Championship-winning Miata (1992)…pretty cool that Miatas are old enough to have their own vintage class and then also have one of the their own ambassadors:

  

Super excited for the season to play out at Thunderhill. Huge thanks to Josh and Cooper for keeping us safe all weekend , Meghan and Oliver for taking care of the snacks and the tire recycling. I love that event. CSRG is magical. If you haven’t been to one those events you ar emissing out, so come on out! WE’ll be posting out race scehule soon after the holidays.

 

CSRG Finale 11/1

ROB: Every year CSRG ends their season with the Finale at Thunderhill. This event is lightly attended and results in tons of track time. There’s an Enduro on Sunday with with a faux LeMans start… and it is just rad. The Saturday night dinner is a special event and we are seeing more and more people showing up. It’s been two years since I have had my Datsun 510 out and it was a great way to end the season racing it. 

 

Troy Ermish brought his 510 and we had a really nice B-Sedan field with a ton of Dimes out there. Most important 510s to us obviously include Tom Dockery and the return of fire captain Todd R,  Noah, Tom, Alison and Rob was out stable for the weekend:

 

It was just awesome having so much track time. Everybody was kicking ass and taking names, and by Sunday afternoon I think we’d all kind of figured that we’ve had enough track time which is unbelievable for us to say. Once again Josh and Cooper kept us all safe all weekend long and we rocked it. Oliver was on tire recycling duty and Meghan on snacks while enjoyed the small town feel of Willows.

  

We enjoyed Saturday night dinner with CSRG and it was so much fun to see everyone. I hadn’t seen Josh Moriarty in a long time and he was out there kicking ass in his 510. There was a really great group of these ex-GT3 cars (tube frame/ fiberglass bodies).  Jim Froula was in one (240SX) and a kid I run Spec Miata with (Joseph Carl) was out there with his Dad in a super cool vintage 1st-gen GTU RX-7.

ROB: We had perfect weather and another race reason in the books.  Can’t wait for 2026 we are super excited and will be traveling this year. There will be a big Japanese big-bore/bash with Sovren in the PNW and I’ll be going to the Rose Cup at PIR in my Miata. Get out there and race! If you have any questions/thoughts about racing with us please contact Rob at rob@zcargarge.com

Tom Dockery

 

Tom Dockery continues to enjoy racing in his Ex-Norm Balzer B-Sedan 510. Here is his report from both CSRG events along with some great in-car footage

TOM: The Sears Point Challenge was a fantastic weekend filled with learning and improvement. With Kenny, Noah, and me as students, Rob skillfully coached, challenged, and encouraged each of us to push our limits. As a result, I managed to improve my lap times with each session, achieving a new personal best at Sonoma.

 

The CSRG Finale at Thunderhill was fun, although it had its frustrating moments. We shared track time with the higher horsepower group 8 machines during all 10 sessions. The frustration stemmed from some group 8 drivers opting to start from the back of the field despite their qualification times. As they worked their way through the field, they didn’t always take the easiest path, requiring slower drivers like me to let them pass, which affected my race pace with competitors I hoped to stay with.

Volume up and enjoy. in-car video action from Tom Dockery’s Datsun 510!

 

TOM: There were positive aspects too. I learned the freight train signaling method to coordinate with teammates at the start. Noah and I used this technique to block a NASCAR Cup car that tried to prevent the faster B-Sedans from overtaking in the corners. Josh and Cooper provided excellent support on both weekends. At Thunderhill, Josh performed a fuel pump swap while Cooper replaced a lower radiator hose, ensuring we didn’t miss any sessions.

This 1971 Datsun 240Z has a long history with Z Car Garage. We have known owner Rob J since the early 90s, having worked on his previous Z cars, and with a few ZCG touches this Series 1 continues to impress. Let’s take a look at how Rob J got into Z cars and what makes this one special.

 

Datsun Z Family

When Rob J was a kid, his dad bought a 1971 Z (photo below) and used to cruise the Santa Cruz mountain roads with Mom in the passenger seat and his two brothers and him sitting on the luggage deck with their feet tucked under the seats:

“His idea of fun was to chuck the car into turns on Hwy 9 or Skyline Blvd – causing the 3 of us to squish into each other with the G-forces. I fell in love with the look and sound of that car when I was 5 years old and was determined to have one of my own. When I was about to turn 16, my brother crashed that car and Dad sold off the wreck, so I never got to drive it. Nothing “sets the hook” like being deprived of something you really want and I bought my first 240Z as soon as I could save up the $3500 that decent cars were going for in the 80s. I’ve had Zs ever since”

 

His first car was a ’71 that was stolen and crashed beyond recovery by thieves. The second, an Iris Blue ’72 (above right), was his daily driver for more than a decade and gradually benefited from ZCG upgrades. When Rob J had the opportunity to buy Paul Hooks’ S30 he sold the Iris Blue Z car to Tony K.

“When Rob Fuller first came to California to work on Datsuns, we had a regular gang of Z drivers going to track days together. The illustrious Paul Hooks was a fellow track nut and this Z was his car. He had done his restoration and modifications the right way – as a closely spaced series of coordinated upgrades using the best gear available, and the car always impressed me with flat cornering, powerful breaks, and that throaty 3.1ltr engine. So when I eventually had an opportunity to buy it from him, I jumped. “

 

Rob J with the Z he’s longed for:

 

Performance to Stand the Test of Time

Paul Hook’s Z was built in the late 90s/early 2000s, so it has the very same 3.1L L-Series engine with triple-Mikuni induction backed by a 280zx 5-speed and R180 LSD. Period suspension upgrades included 5-way Tokicos w/Eibach springs, ST f/r sway bars and sticky Advan A032R tires (remember those?!). The interior has a roll bar with harnesses, Recaro seats and rear strut tower bar.

 

The ethos of this build was centered around open track day events that Paul enjoyed.  Increased braking performance was achieved through a 4-wheel Porsche 911 Turbo “Big Red” caliper brake kit. It works pretty well, but not as well as our Z Car Garage Big-Brakes with respect to pedal feel/un sprung weight…all benefits from our years of experience and collaboration with Stoptech engineers.

 

What makes this Z special? It was built in a period where Z cars were not deemed “collectible” or valuable yet. Despite this, we were building high-end Z cars that performed really well on the street and track. Perform on track indeed; for a car built nearly three decades ago Paul’s vision and execution is impressive. He was a track hound and this Z was his tool of choice, calling routine track days “high-speed mediation”.

 

This ’71 being a Series 1 offers the lightest S30 chassis and paired with 191whp (modest by today’s standards) from the 3.1L it’s tremendously rewarding. It makes all the right noises too, just listen to Paul blasting down the front straight at Thunderhill Raceway (video below) in both rain/dry conditions!

Mini Z

 

Paul’s Z was special to many, including myself. It was “the one” in my eyes seeing how it did everything well from track days to cruising around…the epitome of balance in the S30 chassis. I admired it so much that I made a 1/24 scale model replica with loads of details based on hundreds of photos I accumulated over the years. In 2008 while attending a ZCG Dyno Day I finally presented the model to Paul. More pictures in the gallery below!

 

Updates and Upgrades

So what does this already well-sorted Z need? We discussed a list of needs/wants with Rob J…including sticky tires, new exhaust system to ZCG-spec, and a transmission upgrade. The aged Hankook R-S3s were replaced with Bridgstone RE-71R in 225/50/16 over those classy Panasports:

 

The 280ZX close-ratio gearbox that Paul had was getting old and noisy. At the time we were doing Nissan KA24 (FS5W71C) transmission swaps (before the CD009a came to market) by modifying a 280Z L-series bell housing. You can see the custom ZCG transmission mount below.

 

A JWT heavy duty clutch and Z32 shift knob finish the swap in style.

 

The Z had a really old-school Crane HI ignition components. We updated to run the MSD box so Rob could tune the car and extract a little more power. The exhaust was replaced with our ZCG exhaust system and a Koyo race radiator installed.

   

Rob J was happy with the updates:

“Recently, I took my car into the shop for an exhaust system upgrade and electrical system maintenance. What I got back was a different car entirely! Rob and the crew replaced my old school exhaust, which was frankly an eyesore, with ZcarGarage’s current system, which is expertly tucked up into the undercarriage and finally really looks the part. The exhaust isn’t louder, but it’s more sonorous and less tinny sounding. I love it.”

Dyno Tuning

It has been many years since this Z had been on our dyno. We adjusted the valves, set timing, sync’d carbs and re-jetted them for the new exhaust. Baseline was 198hp/194tq and after Rob’s tuning the Z made 222hp/213tq at the wheels. More power even after all these years this Z does not disappoint!

Power gains you can feel!

“The improvements are awesome: approximately 25 more HPs and 19FtLbs and much smoother power delivery. The car leaps down the road when you mash the throttle and no longer stumbles when rolling into the throttle from cruising RPMs.  The car was fun before and now is just crazy fun.”

Enjoy the dyno video below as well as some historic footage of this Z in action. Volume up!

 

Enjoying The Ride

 

We love how Rob J is enjoying his Z, just as Paul Hooks did. Rob has attended many events and fun runs and I still can’t take my eyes off this Z! In case you are wondering, his plate reads “Kenjuru” to note the martial arts he practices 🙂

 

Below are just a few of the great times we’ve enjoyed with Rob J and his ’71 Z:

Happy New Year!

Bayline Vintage Meet Pictures!

EVENTS: Driving While Awesome Cars n’ Coffee 11/10

EVENTS: Cars and Coffee at Canepa Motorsports

Long Live The Z!

 

Plans for the future…we will continue to keep this Z on the road and give Rob J updates like our Z Car Garage Big-Brakes, and Z Car Garage CV Axles.

“This 240Z is a late Series 1 manufactured in December 1970, so it’s not a low VIN car (17,XXX) and I don’t feel any pressure to restore it to stock.  Instead, we’ll keep upgrading the go-fast options while keeping a vintage look.  I truly love driving this car on the street and the occasional track day and I love doing both with other Z Datsun enthusiasts.” 

 

 

Thank you Rob J for supporting us and being in our life. We are so happy you found the right Z and ZCG will always be your home! DO IT IN A DATSUN

Here at Z Car Garage we LOVE to drive our cars on the racetrack. Open “Track Day” or High Performance Driving Events (HPDEs) are excellent venues to familiarize yourself with a car and its limits while having fun in a safe, controlled environment.  Two of our customers recently shared their first track-day experiences with us and they had a blast!

 

We supercharged Robert C’s G35 last year and he decided it was time to do his first track event at Laguna Seca Raceway. He’s added these gorgeous RAYS Gram Lights 57Xtreme wheels since his last visit:

 

“Rob!
Just want to tell you I had a incredible day at Laguna. David Ray is a great guy and awesome teacher. We spent the first three session working on line, smoothness and consistency with both until I had all 11 corners worked out. The 4th session we put it all together as he pushed me and it was phenomenal! When I IR’d the front rotors after the session I was over 500 degrees and they were smoking. Happy to report brakes are still great and no warpage on the rotors. Ironically David mentioned doing an ST40 upgrade which we already quoted earlier so know that is still on the radar for my next track day. Nice to have someone just back up a buying decision without asking. I did graduate to Solo and was told to register for Group B next time so pretty pleased about that. On the upside I have marked “Drive my car at Leguna and hit the corkscrew” off my bucket list. On the even bigger upside I’ve added “1) Go drive Laguna more. 2) Drive Infineon. 3) Drive Thunderhill and 4)Drive Buttonwillow.” to the list.

David had praise for the current work done on the car and I have to agree. The work you and team have done since October last year has made this car even more enjoyable and something to proudly run on a track. The car had zero issues and feels no worse from the day.”

Robert C.

 

In October we added some bolt-ons and tuned Garth J’s 350z preparing him for a day at Thunderhill Raceway:

“Hi Rob,

Thunderhill track day was awesome a few weeks back. Car felt great. The Bridgestone S04’s were a major upgrade. Thanks for preparing the car for a great experience. I’m thinking about auto-crossing next season.Will be needing some routine maintenance in the new year. Can we schedule something mid January? Happy Holidays.”

Ready to experience your Nissan/Infiniti on the track? We can help!

It’s raining GT-Rs at ZCarGarage! Owner Kevin K had a blast driving his GT-R at Thunderhill recently. You might remember seeing his car at ZCG for several mods including an exhaust system, wheels/springs and a few other items. Kevin also displayed the GT-R at the SJ Auto Show in January. These awesome on-track pictures are from Gotbluemilk.

How cool does this R35 look at speed?

Kevin had an impressive list of parts installed including:
-Deatschwerks 750cc injectors
-Cobb AccessPORT, Custom tuned by HorsePower Logic
-Clear Bra by Premier Protective Films
-Downforce Carbon Fiber body kit by none other than Williams Auto Body
-Go Fast Bits blow-off valves:

Check out the AMS Catted Downpipes, compared to the OEM units:

The stock rear section of the exhaust was replaced by this beautiful HKS Legamax Exhaust:

The center section leading up to the downpipes was replaced by a GTM Challenge Race Spec non-resonated midpipe:

It looks and sounds amazing!

Kevin has great taste and chose some very sharp Volk Racing TE37 G2 wheels finished in Flat Black: 20 x 10 F, 20 x 11 R. Combined with Swift Springs and carbon fiber lower trim this GT-R looks sinister on the street and on the track!
