How to decide: TPC supercharger or Twin Turbo conversion? Detailed analysis.
#46
Eric,
thanks for the analysis... looking forward to your results. I am also on the same fence (for future mods). I would rather hold onto my car and not have to trade up to tt - in the spirit of upgrading and nostalgic value etc. etc. Also interested in the track use feasibility. The turbo conversion definitely seems like the better choice. I know you've pulled the trigger on Protomotive... but just curious if you had looked at the powerhaus and the turbokraft conversions?? If so, why protomotive vice the others? ($$$?) Good luck and keep us posted. Thanks...

Eric,
We were in the same position, but I decided to trade up. I'm facing a bigger re-learning curve, and other unexpected expenses and challenges that were solved in my 993. Do you still have the stock gear ratios? That made a really big difference for me. Anyway, this is about more than power...it is an adventure, and I'm really eager to get a ride with you and share the thrill. I'm waiting with baited breath......

Thanks everyone for the encouragement. I'll probably need it once I start installing!
Tomorrow, according to FedEx.
Turbokraft's price is much higher- $18,500 - and they require you to ship them your car. Plus they've only done 3. Can't remember why I ruled out Powerhaus, but I know they also don't allow DIY.
If you're going to Mid-O with the Audi club on July 4, you'll definitely get a ride. Shon & I signed up.
Tomorrow, according to FedEx.

Here's a pic of the Protomotive kit installed in my car (pass side). I've driven the car, but I'm withholding any commentary until I've broken in the turbos and can get into the boost. A full writeup is coming once it's all done. Still working out a few little kinks but looking ok so far.

Install went ok, but I feel it's almost too early to say since I haven't really fully tested the system. Hardest part so far was removing the intake runners, left and right, which was required to get to the oil supply. I spent a total of around 45 hrs so far, but that could easily become 65+ depending.
When you remove the bumper cover, you're left with this thin metal heat shield that protects the plastic bumper. It doesn't look that bad in person.

Looking good! I am patiently awaiting your full writeup. My only concern is turbo lag with all that piping and bends. Protosport, a compnay that resells and installs this tt kit claims turbo lag is less than a stock 993 TT due to the compression of the na motor. I will await your feedback. Great job with install!

Looks pretty good so far. For the oil supply, did you tap into the housing for the oil pressure sender?

p.s. as you can see, the SAI system went bye-bye. No need, since I dont' have cats now anyway.

Yep, that's it. Let us know how you like it once it's all broken in. Although it's much different then yours, my NA-based turbo setup has been a blast.
