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!”

“Great Drives” is a Zcarblog series highlighting scenic routes and destinations we have enjoyed from the past and present. Whether it is a nice cruise or thrilling adventure, we hope to inspire Bay Area vintage car owners to Enjoy The Ride! Have a great drive of your own that you want to share? Feel free to contact us on Facebook, Instagram or by e-mail.

 

Mt. Umunhum to Alice’s Restaurant, October 2018

There are several fun routes reaching Alice’s from San Jose. This drive was organized by Lotus 7 owner Geoff W and we all met in Almaden to begin:

 

The 11-car group was diverse with both vintage and modern sports cars with great Nissan/Datsun representation!

The cars:

Daniel’s Nissan 240s (S13) with an RB25DET swap. He is the man behind the lens of BayRoadsAP. Naveed Yousufzai’s R32 Skyline GT-R:

 
 

Lane Skelton of DrivingWhileAwesome in his Porsche 944. Eric in the 911 Targa

 
 

TWO Z cars! Michael’s Series 1 240z (with patina) and Andrew’s Series 1 Fairlady Z (RHD!)

 
 

Geoff (organizer) in his Lotus 7, featured on Petrolicious! Mike in his 993 Porsche:

 
 

Matt in his Subaru BRZ Performance Pack, Brendan and Drew in their Chevy SS sedans, and myself in the Datsun Roadster.

The route:

 
 

Driving through Almaden to Mt. Umunhum:

 

The climb up to the peak is filled with freshly paved road and switchbacks. At the top:

 

In the lower lot we had a few minutes to chat and check out the cars

 

I really dig Michael’s S30, it has a warmed-over triple-carb’d L-series:

 

We left Mt. Umunhum towards 17 and exited on Bear Creek Rd. for lunch in Boulder Creek. This was a fun stretch I haven’t been on.

 

Heading up 9 to 35. It was fun chasing Michael in the Z:

 

 

We had a little scare when his oil pressure gauge started reading low….it checked it ok and we were off again:

 

The route changed a bit and we took Alpine Rd. (lots of loose gravel) to Pescadero Creek Rd, then Stage Rd. After re-grouping we hopped on HWY 1N:

 

From 1 we turned right onto 84. This stretch was amazing. SO much fun connecting the turns and chasing Geoff in the Lotus. This is a road that made me love my roadster even more. Thanks Geoff for an exhilarating drive!

 

All of the Roadsters at Alice’s Restaurant. An “Aero Cycle” joined:

 

We also got a closer look at Geoff’s go-kart. One look at the driver’s seat tells all: this is a wild ride!

 

After drinks we departed. Alice’s never disappoints.

 

Here’s video I snapped showing the action, enjoy!

 

After drinks we split up for home, and i took 35 back down 9. I was treated to some great coastal and bay arae views:

 

 

Big thanks to Geoff for organizing the drive. It was a fantastic run with great company! More pictures in the gallery below.




The Sleeper: Dave’s 1972 Chevelle

No, dear readers your eyes aren’t deceiving you! That is a 1972 Chevelle coming out of Turn 9 at Laguna Seca and here is the story behind this icon from the 70’s.  Owner Dave T was scouring the internet for dyno shops when he found Z Car Garage. With an endorsement from his co-worker an e-mail was sent and we happily obliged to dyno the Chevelle. We love muscle cars!

Dyno (1 of 1)
 

Dave had assembled this engine entirely by himself and wanted to see the difference a new exhaust system made. The stock exhaust consisted of OEM cast-iron manifolds, dual pipes w/o crossover and generic turbo mufflers. Baseline numbers were 277hp/326tq to the wheels. The new exhaust system included Hooker SBC headers, Pypes X-pipe and Race Pro mufflers. This helped produce 330hp/356tq to the wheels!

Here is a video of the dyno run:

 

 

What we love most about the car is that it was meant to be a ‘grandma’s sleeper’ that could work at the road-track, the drag-strip and as a daily driver.  It still has its original bench seat and column shifter. Dave has logged over 11,000 miles on the motor and recently completed a track day at Laguna Seca!

Dave actually built the engine before he found the car. After the successful engine run on the stand, his dad encouraged him to find a car for it:

“He said, why don’t you get a Chevelle like you had in high-school- that was the best car we ever had. I had received a 1972 Chevelle Mailbu from my parents at the age of 16. It was blue with a white vinyl top. I had an accident in it and some time after that the cam/timing gear let go and although I tried to replace it the engine never ran right and we ended up donating it to the high-school auto shop class.”

He then found a ’72 on Craigslist in un-modified condition, shown above in the original owner’s driveway. The car has been repainted it’s original shade of green, and that’s it. In went the new motor and he’s been driving like mad.

Here is Dave putting the Chevelle through its paces at the Sear’s Point Drags (Sonoma Raceway). His first time out he ran low 13’s!
