You DO realize that most engines that are aftermarket turbocharged like your engine will be, seamingly tend to not be soo reliable right?

Also, you seem like you know what you are doing, but you said you want a fast/reliable car. Two problems with that sentence in my opinion. One, the fast part. Your sticking with a stock compression motor, a small turbo and a near stock fuel system pushing 4-5psi. This isnt going to be as fast as you think it is I dont think. As any car is going to pull with a turbo, 4-5psi isnt very much. I bet it inproves your 1/4 from a 16 to maybe 14.8-15.5. I could be wrong, but that are the numbers I have seen with that much boost. Two, the reliable part that I already blabbed on about above.

I think you should go back to your original plans in your first post.
