To all you 914 Turbo naysayers and asshats!! I just wanted to share an email from the buyer of my Turbo'd 914:
"Rob Talich's vision for this engine is now a reality! The engine runs great in this 914. It needed to be tuned - no easy feat (especially at cold start), but now it's complete! I had a Porsche tuner friend that completed the exercise and he worked directly with SDS to complete the tuning for this engine configuration (see Rob's initial posts on engine details.)

Leak down on engine ranged from 2-5% across cylinders. Raby and Original Customs delivered Rob a great engine.
Everyone kept telling Rob that the engine needs an intercooler due to high temperatures. We ran the engine on the road for extended periods of time (>30min), and cylinder head temp did not exceed 300 degrees. So (like Rob), I did not put one in. If it were to become a concern, then adding one would be the solution. Note that in 1976, Porsche did not put an intercooler on the 930 air cooled Turbo - just a data point.
My goal was to complete the work started by Rob. That is done. I never intended to keep the engine. I have now parked the car, and working on another project (77 911s). I will pick up the 914 project when I secure a 2.0 motor (maybe a 2056 build from Original Customs.)
The 2.6 turbo is TOO MUCH engine for me and this car. The car is in amazing shape, and I would like to return it to stock.
If you are interested in the engine, I am interested in selling just the engine, EFI, and oil cooling. I believe Rob invested over 15k in parts, and I added 3k in tuning and re-wiring. I would like 9k for the engine package."
Soooo.... you CAN turbo a 914 if you know what you are doing OR involve the right people.
