TUNING: Geoff’s 1972 BMW 2002

Filed under: 240z,Featured Cars and Projects,Great Drives,Performance
by Alvin G @ 2:02 pm on December 8, 2023

 

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!”

Fast Intentions Exhaust for the 2023 Nissan Z

Filed under: 370z,Featured Cars and Projects,Nissan Z,Parts
by Alvin G @ 5:34 pm on December 6, 2023

 

When we acquired our new 2023 Nissan Z the very first modification was a Fast Intentions TDX 2.5″ Cat Back Exhaust System. FI makes the best exhaust for late model Nissans/Infiniti sports cars, If you have an RZ34 this is the one to get with high quality, great fitment and a wonderful exhaust note. Enjoy our review with photos and video below.

 

We watched Fast Intentions grow as a company and they have never compromised their quality. Z Car Garage has installed and tested many FI cat-back exhausts on the 370Z/Q60 sports cars, the fit/finish for their 2023+ Nissan Z system is equally impressive:

 

OEM and Fast Intentions exhaust installed before/after:

Dyno Proven Results

 

The Fast Intentions Cat Back exhaust system also provides solid power gains. We performed before and after dyno runs on our 2023 Nissan Z Performance 6MT and saw 388hp/392tq with the OEM exhaust and 399hp/394tq with the Fast Intentions exhaust. Expect even more with tuning:

 

Enjoy this video demonstrating the Fast Intentions exhaust on our 2023 Nissan Z. You can see and hear it in action with hot/cold start, acceleration, drive-by and in-car footage:

Enjoying The Sound

We have put a few thousand miles on our Fast Intentions exhaust and it still looks and sounds fantastic. It has been through many dyno passes, track days and mountain runs.

 

Running as Official Pace Car of CSRG:

TUNING: Tyler’s Porsche 914

Filed under: Featured Cars and Projects,Performance
by Alvin G @ 9:14 pm on December 3, 2023

 

Tyler has been in Rob’s life since he started working as a head engineer at Stoptech. He is behind Research and Development of our Z Car Garage Big-Brakes, and we couldn’t have done it without his drive and passion. Our collaboration with Tyler always results in excellence, so when he mentioned bringing his Porsche 914 up from SoCal we happily obliged to work on it.

 

TYLER: “Rob Fuller/ZCG and I have known each other for a while now through my Engineering work at StopTech. We developed the Z Car Garage Big-Brakes for small wheels together. During the development of the BBK, Rob Fuller the man himself would constantly call me and leave hilarious singing voicemails, mostly him belting out hair-metal versus then saying “CALL ME BACK!”. We really hit it off during this time and grew to have a deep respect for one another.”

 

“I think we were able to really nail the final product after lots of tweaking and testing. ZCG was stoked with the BBK and I was stoked to work with such an amazing shop and crew. This project has always been a highlight for me. So when Rob asked me about my 914 and heard about my troubles with it he instantly offered to help out. This was definitely an offer I couldn’t refuse, so I brought my 914 to the shop.”

 

History

 

Before we go into the work ZCG performed let’s hear from Tyler about his 914…

TYLER: My first car was a 1973 914 2.0 my Dad, brothers, and I bought for $1200 ~25 years ago. We fixed it up and started to race it together, we still have it and plan to get back to racing it one day soon. Ever since then I wanted another 914 for myself. I just like the fact that 914s are mid engined, air cooled, and has a horizontally opposed engine, all of the coolest Racing Porsches are in this configuration. Also the 914 is three more than a 911, so there you go. When I saw the 914 on a Tucson AZ Craigslist post in 2015 I knew I had to snag it. The car was an old PCA/POC race car that raced in the 70s and 80s in AZ. I knew the car was a diamond in the rough even though it wasn’t running and had many problems to address.”

 

“I ended up buying it from someone in Tucson AZ for $3000 and towed it back home. Ever since then I have been fixing it up and getting it running well enough to enjoy classic rallies and some track days. I have been sort of converting it back into more of a streetable car but still keeping it raw and sort of rough that still gives you a feeling of a race car. My favorite thing to do is go for a drive down PCH with my wife and my dog squeezed in between us and stop at the beach for a walk and swim or rip the snot out of it on the track.”

Chassis and engine details on the 914 below:

Brakes

 

Custom designed StopTech big brake system. Front 2pc 282 x 28 rotors with STR42 calipers and rear 2pc 290 x 22 rotors STR42. Pads are StopTech SR33 front and SR33 rear with custom SS lines. Brakes are lighter weight than stock and with more thermal capacity!

 

Suspension

Chassis and Safety

Roll Bar, 5 point belts, Frame reinforcements, door jam and chassis stiffening bars, dront fenders are rolled rear are fully flared, battery relocated to the front.

Engine & Transmission

 

2.0 Liter european pistons and sleeves 8.6 to 1 compression, Engine balanced and heads machined, Dual IDF44 Webbers, Mild race cam, High capacity oil pump with deep pickup, Dual rear mounted oil coolers, 4 into 1 exhaust with Supertrap muffler. 5 speed with shortened 3rd,4th, and 5th gears, Short shifter, OS Giken LSD. “Only 914 in the US to have an OS Giken LSD installed that I know of!”

The Z Car Garage Touch

 

ROB:Tyler had his car dyno-tuned previously but it wasn’t running well. We like to make cars better, so we performed suspension work, adjusted the valves, sorted out his carb linkage, ignition system and made it awesome. Upon arrival it had a really bad front windshield install, so we replaced it and the stainless trim. New valve cover gaskets, cap and rotor, re-did the throttle-linkage return springs, serviced the air filter. Basically went through the Porsche like we do with our Z-car clients so he could enjoy driving it again.”

 

Dyno Tuning

With carb work, timing and linkage adjustments the 914 made 110hp/115tq at the wheels, gains of 18hp/15tq from baseline. Tyler was really happy with the results:

 

TYLER: Rob gave my car some serious balls…I don’t have the official numbers of the final dyno run but the car feels like it’s been hitting the gym HARD. Engine runs super smooth, sounds like a completely different beast, starts without issue, is really responsive, runs a lot cooler, and has an overall boost in power! It has increased the enjoyment factor 100%.”

Enjoy this video of the dyno run and Tyler driving home from the shop down to SoCal:

After checking the suspension we mounted fresh Toyo RA1 tires followed by a full alignment in-house. Tyler was ready for the road trip home.

 

If it ain’t the Z-car, please let it be the P-Car!

 

Tyler shared a few photos from his roadtrip down to SoCal, catch his adventures on Instagram. Thank you Tyler for letting us work on your 914 and continued support for our Z Car Garage Big-Brakes. Stoptech or Don’t Stop At All!

TYLER: “ZCG is one of the top shops I ever had the pleasure of working with. As a customer, the experience was equally great. The team is really driven, they have expertise to really handle tricky stuff and strive for perfection with everything they do. I knew my 914 was in the best of hands even though ZCG specializes in Z-cars, their talent easily translated into P-cars.”

TUNING: Alex’s Datsun Sunny Truck

Filed under: Featured Cars and Projects,Performance
by Alvin G @ 12:00 pm on November 29, 2023

 

We have known Alex for many years and enjoy seeing his Sunny truck on local drives and gatherings. He reached out to Z Car Garage for dyno tuning and we happily obliged. The Sunny was already close to being dialed-in so we just put the sprinkles on with a few adjustments. It is such a cool little RHD truck and drives really well.

 

Alex’s cars are built to high standard and have a great vibe. His LS-powered Datsun 510 wagon built by Marcus Fry Racing is well-known in the community:

 

“I met Rob through a mutual friend at the time (Dan from DGR), just about 15 years ago. I helped deliver the Bluebird he has around that time. Throughout the years I have heard great things about ZCG and it only made sense to go to Rob when it was time to get the carbs tuned on the Sunny. My experience was great. The acceleration is now smoother and I got to see numbers. The carbs are now synced and timing adjusted.”

 

Alex recalls how acquired the Sunny:

“I randomly found the Sunny for sale in Seattle a few years ago and pulled the trigger as I have always wanted one but never seen one in person. It was originally brought to the states by JapaneseClassicsLLC a year prior. A good friend, Marcus of MFR, volunteered to go with me and tow it back. Since then, I have had a blast driving and updating as we all do when we get a Datsun to play with. Rebuilt 5-speed, 0 offset Panasports, new rubber bushings and weatherstripping, and getting the seats reupholstered are just some of the things I have had done to date.”

Dyno Tuning

 

Alex brought truck to ZCG and we got it on the dyno. Under the hood is Nissan’s 1.2L A12 engine, also used in the B110 series sedans/coupes. This one sports dual Solex-Mikuni induction. It was already close to being dialed so we adjusted the full throttle, smoothed-out the fuel curve and timing. The truck made 54hp/59tq to the wheels:

 
 

Enjoy this video of the Sunny on the dyno at ZCG:

 

Enjoying the Ride

 

We love that Alex drives the ‘Ute everywhere. He’s a great guy to be around and also an an avid videographer, mounting a Ghostcam on the back of the truck capturing neat driving perspectives. You can see more of his adventures on his Instagram. We’ve had the pleasure of running with him on road rally events like Breakfast Club Rally. I even spotted Alex on HWY 101 S and at a local bar…you can tell how happy he is driving this truck. And yes, seeing a kei car in modern-day Bay Area traffic is quite the sight:

 

We asked Alex what’s next for the Sunny:

“In the future, I want to up grade the suspension and brakes (maybe I can get something ZCG to fit under 13s lol). Since I “somewhat” over modified my LS510, I decided to keep the sunny mostly stock. Soon, I am getting another A12 to use so I can rebuild the one under the hood to OEM.
I have always been a 510 guy, but I can’t help but like to drive the Sunny more.”

We appreciate your support Alex, keep Enjoying the Ride in your Datsuns! More photos in the gallery below
