TUNING: Geoff’s 1972 BMW 2002

Z Car Garage specializes in dyno tuning of vintage cars and this includes non-Nissan/Datsun classics. From establishing a baseline on street cars to preparing race cars for high-profile events we love helping each client achieve the best performance possible. Geoff W’s 1972 BMW 2002 came to Z Car Garage for a dyno tuning session with fantastic results.

 

Geoff is a friend of the shop with a great story behind his love for all things engineering and automotive. Let’s hear how he got into cars and acquired the BMW 2002…

Generations of Car Enthusiasts

 

“My father owned Formula Fords growing up and has owned a Lotus Elan since 1977; we spent a lot of time in the garage together in my formative years. I was exposed at a young age to AutoX and vintage racing I distinctly remember falling in love with Lotus Sevens and B-sedan cars. When I was of driving age, I purchased a 1985 Mk1 Toyota Mr2 (Chassis code AW11) and began to do a lot of track days and AutoX. This eventually led to another 4age powered car: The Toyota Corolla GTS (Chassis code AE86). I was going to college in southern California at the time and was involved with Club4ag.com which started holding drift day events. This was before professional organizations such as Formula D came about.”

 

“As a poor college kid, I started working drift events and track days in exchange for track time. I eventually became an instructor and won one of the earliest US drifting competitions in my largely-stock, daily-driver Corolla. After school, I bought a Caterham 7 Super Sprint, and while it was fun, it was never quite the original Lotus Seven I pined for. I eventually sold all of my “fun cars” to fund a house purchase in San Jose. After a few years, I finally acquired my Lotus Seven in 2013 as a tired vintage race car from Texas. I built a road-going motor and installed a synchromesh transmission for the car and finally got it running a year later.”

 

“I’ve been enjoying driving and developing it in the years since. Alvin from Z Car Garage and I met a few years after this car was finished and we became fast friends. Some of my best memories with this car have been spent driving in the mountains surrounding San Jose with Alvin. I’ve done a few vintage car rallies and been on track with it, but I eventually would like to do some vintage racing.” (See Geoff’s Lotus 7 in this excellent Petrolicious feature HERE)

 

The Inka Orange 1972 BMW 2002

“In 2018, I sought out a B-sedan road car to take on vintage car rallies and have something fun to drive in inclement weather. Alfa GTV’s, Datsun 510’s were out of my price range and I couldn’t find any Mk1 Ford Escorts/Cortinas for sale. I began looking at BMW 2002’s; I especially liked them in bright/interesting colors popular in the early 70’s.”


“When I bought this car, the previous owner didn’t know much about the engine. It had a pair of Weber 40dcoe’s, ran well, and seemed to feel like other stock bmw 2002s I had driven. I haven’t made many changes to the car, but did locate and install a set of rare and period correct Campagnolo wheels. Earlier this year, I found and purchased a Mk1 Cortina and I was going to sell the BMW 2002 because it wasn’t as exciting to drive.”

 

Dyno Tuning

 

The 2002 baselined at 99hp/114tq and after tuning put down 129hp/127tq at the wheels! Let’s hear from Rob…

ROB: “Being around so many B-Sedan race cars I wanted to see what all the hype was surrounding the BMW 2002. I started talking with Geoff about trading one of my S30 Z cars for his BMW. He kindly lent it to me, and I drove it to the Monterey Historics to root on our friend Jim Huff in his Neu Klasse BMW. First impressions were that it was anemic and the dyno confirmed this. Full-throttle was compromised so it needed throttle-linkage adjustment plus timing and jetting. It really came alive making great power…

 

Enjoy the video below to see Geoff’s BMW on the dyno, test driving with Rob and enjoying a few road rallies:

Hold on to that 2002!

 

Rob and Geoff recall how they felt about the 2002 post dyno tuning and test driving:

ROB: “With +30hp/13tq this BMW was born again, and man did I like the German 510. Love the visibility, greenhouse, seats, thud of the door closing. Despite being a die-hard Datsun 510 guy I really dug the 2002. Enjoyed it so much that I thought maybe this was going to be my first German car. I drove it, Meghan drove it, and just as I was getting excited, (un)fortunately Geoff finally drove it…our improvements to the car convinced him to keep the 2002.”

 

GEOFF: I hadn’t even considered having it tuned, but Rob suggested giving it a try. When I drove the car after Z Car Garage worked their magic, I was absolutely floored. It is a completely different car now, gaining 30 horsepower and this was not the “stock” 2002 I had assumed it to be. I’m absolutely kicking myself I didn’t have it tuned by Rob earlier. Needless to say, I am no longer interested in selling it. I feel like I’m experiencing a whole new car I cannot thank Z Car Garage enough!”

On Datsuns:

 

We introduced Geoff to the magic of the Datsun S30 Z car after joining him on local mountain drives and rallies. He gets it…

GEOFF: “Being around the shop, I have an even stronger strong appreciation for both 510’s and Z cars. I was recently given the opportunity to drive Mrs. Butters and was completely blown away by the Z Car Garage Big Brakes. I have never felt brakes like that on a vintage car; they’re more impressive than most modern cars! The sound of that L-series on triple Mikuni’s is absolutely intoxicating. While I’ve always preferred smaller/lighter 4 cylinder cars, a S30 tuned like Mrs. Butters is definitely on my short-list of next cars to own. It also helps to have a reputable shop so familiar with these cars in the area!”

 

Friendship

ALVIN: “It really is a small word. Geoff and I both work at the same company and didn’t meet until we saw our beloved vintage cars featured in Petrolicious. Since then we’ve enjoyed Bay Area backroads and beyond. Good times from running rallies with Driving While Awesome, to attending race events and weekend blasts. Geoff is truly someone I’d wish I had known earlier in life. Here’s to more memories and drives.”

 

Just a few events we have enjoyed with Geoff over the years, with more photos in the gallery below:

EVENTS: Cars and Coffee with Driving While Awesome!

EVENTS: Super Drive Sunday

EVENTS: DWA Rally From Home South

 

ROB: “Happy to help Geoff sort out his BMW. He’s such a great car enthusiast and friend to the shop, myself and Alvin. Wonderful 2002. B-Sedans are not just Datsun 510s, they are in the form of BMWs, Alfas and other marques!”

Every 2nd Saturday of the month there is a Cars & Coffee gathering in San Jose, only 1-mile from our house!  My neighbor invited me to this event held at the Starbucks on Hillsdale Ave yesterday. We left together with the roadster and his Barracuda:

EVENTS: The SEMA Show!

What Happens in SEMA . . .
Every year the Specialty Equipment Market Association (SEMA) takes over the 3,000,000 square feet of floor space at the Las Vegas Convention Center for a weeklong trade show that covers everything automotive. Exhibitors feature cars, trucks or SUVs in their displays to showcase their products or simply to attract attention. In a town where weird is normal, the masses of over-the-top and extremely modified cars seem at home inside the multi-building center.

IMG_8551IMG_8264
 

Tens of thousands attend the SEMA Show each year, and while a trade show and not open to the public, it’s the one auto show every enthusiast wants to attend. Despite the propensity for depravity that comes with a no-last-call town, SEMA is never anything short of a legendary gathering and we had a blast during our 2-day visit.

 

Nissan-Datsun-240Z-OS-Giken-S30-02-640x427

SEMA 2015 marked a special milestone for the crew at Z Car Garage as we prepared a special 1971 Datsun 240z for display at the show.  Through an exclusive collaboration with OS Giken we unveiled the world’s first North American (LHD) S30 to be powered by the legendary TC24-B1Z engine. This mythical twincam cylinder head bolts onto an L-series block giving it crossflow breathing and high revving operation.

The Z was well received by show goers stopping by the OS Giken booth which featured video displays of the engine being assembled and tested at ZCG. Jaws dropped at the sight of the TC24 and we also heard admirable reviews from fellow Datsun/restorers for the build. Our friends at Japanese Nostalgic Car (JNC) and Speedhunters featured the car in their SEMA reviews:

The lucky owner of this OS Giken-equipped Z is our friend and customer Gary Stephenson. In short, his build highlights our restorative powers and sports full suspension (allowing 255/40/17 tires under stock flairs), our ZCG Big Brake Kit, nos OEM glass, integrated roll cage,  KA24 transmission, Recaro Competition seats and more.

In current tune/configuration the TC24 produced 376hp/281tq to the wheels on 91 octane, proudly displayed by the car at SEMA. This Z will be driven on the street and track so stay tuned for videos!

Huge thanks to the crew at OS Giken for a killer booth and memorable experience. Look for an in-depth story about our collaboration with OS Giken and TC24-B1Z build on the blog soon.  Long Live the Z. Here comes the TC!

Datsuns Everywhere at SEMA!

Our favorite vintage cars were in great numbers this year. One of the most prominent of course
was Sung Kang’s 1973 Datsun 240z affectionately called “FuguZ”.

11220797_1634816083434430_5240671915459417167_n

Sung ( “Han” of Fast and Furious movie fame) chronicled the build through social media, enlisting parts from around the world with final assembly by Kenji at Greddy. Sporting the latest Rocket Bunny body kit, Volk TE37s and an ITB’d RB26 drivetrain this was a crowd favorite and inspiration to all. Congrats to Sung and the Greddy team for an epic build!

For the first time in SEMA history a Datsun roadster was on display courtesy of Socal specialist Kevin Desirello.

This fully restored 1967 SPL311 was treated to a complete S15 SR20DET drivetrain swap but Kevin and his team didn’t stop there. By adding a VVL head and punching the displacement out to 2.2L, they essentially made an SR22VE-T with power levels of 450whp anticipated!

 

IMG_7995IMG_7993
 

Garret wanted the car for its SEMA booth and it was placed alongside the famous Mad Mike Whiddett’s insane twin-turbo FOUR-rotor powered Formula-drift Miata. We are especially proud of Kevin and his roadster for making it to the Top 21 in The Battle of the Builders competition!

This Datsun 520 pickup was actually a contender in the Optima Batteries challenge with a Mazda Miata drivetrain and double A-arm suspension F/R!

Hakotora! Take one Sunny ute and graft a Hakosuka front end on for a mean little pickup. This build had some great details and a built SR20DET under the vented hood.

This BRE 510 was on display in the Tokico booth. A celebrity driver car, this is now owned by Datsun-freak Adam Carolla. Our hero Pete Brock was not too far from the dime!

Eric and Josh from JDM Legends made the trek from Utah and displayed their superbly restored Ken and Mary Skyline. The C110 had all the choice parts from the triple-carb’d L-series, Comp seats and Watanabe wheels.

There’s a New Boss in Town . . .

Not Datsun per se, but the following Nissan 240sx (S14) sports cars all have one thing in common: The “Boss” aero kit from RocketBunny/TRA Kyoto. The kit transforms the front end of an S14 into a B110/Challenger looking vehicle… it takes some time getting used to, but we dig it.
