Just read thru the tips in this forum, run the bottom end rich, and you'll be set....
It's interesting, you have had the three engines I was considering. I am familiar with OS and since the JLR is based off a Picco, I figured it was good. I have not heard a lot about the D3R or any of the STS .12 engines for that matter. The JLR is the best price and has great support at the local track. I am over-thinking this. Maybe I will build a G4S as a rain car and drop an STS in for testing.
