But I don't want to. If I can get a nice increase by spending $500 I'll do that. But if it will cost $2000 just to get anything significant then I'll just pass on the whole thing till I finally put in a 20B. Fortunatly I can get a front clip for really cheap. And I have the mechanic who can help me drop the motor in and tune it with no sweat. But I'm going to wait till my N/A motor dies before I replace it. And until then I want to build around it so everything will be interchangeable with the 20B. Dropping $500 for a fuel controller and what not won't hurt me at all. But if it won't make any real difference then I'll just forget it and wait till I put in the 20B.

 

^ This is a better plan. The 20B swap will cost about $10,000, so it sounds like you would be better off just saving your money now rather than spending it on a stop-gap measure.

Then keep it stock for now.
