TUNING: Tyler’s Porsche 914

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.”

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.”
