I'm running in F Prepared in my Boxster S. My first question is why you are going with the 2.5. Per SCCA, I think you have to stick with the stock engine, but can go up if a larger engine was offered later. My biggest FP competititor runs a 71 911 with a 3.6 from a 964.
I'd be really happy if I could get around 7lbs/hp.
I'm at 2637 with full doors & passing VA state inspection. I think I could get down to 2500 and still pass, but it would be $$$
