Engine builds - who did you use

The definition of insanity is doing the same thing and expecting different results.

At this point, going elsewhere, just for the piece of mind, is worth a lot of money. I can't understand how they could mess this up that many times.

There is no way I would send them my car after this experience (meaning send it back to them to fix).
 
You can go with Ronnie at RD Engineering in Oxnard or James Wie with ACG in San Diego. Both are good. I would not go to SP Engineering, although they built my engine and I have not had any issues with it. I had to replace the transmission and trubos, though.

RD uses a 30mm turbo setup to get close to 1200 at the wheels. That is a very fast spooling turbo. I have the elite prime turbos on my car which are 35mm turbos.
