I am running on stock twins now, but one of my turbos is going out. I would like to get a single setup but don't have the money to do everything with it. Is there a small single I can buy that will be supported by the stock fuel system? Another thing is once I get the rest of the car up where it needs to be I would like to be able to just swap to a larger turbo. Thanks for the help.

 

You could run a small single with the stock fuel system pushing about 5 lbs of boost.
You could run around 11lbs as long as you have a computer that can control fuel and timing, such as a Haltech or Power FC.
My opinion is if your going to go single do it right and do most of the stuff at once. Its the safer way to do it. Your playing with fire if you do it any other way.
