axisrc, I wouldn't suggest a Surefire .32. It's just not a very good motor. Believe it or not, but a lot of the top racers around Chicago who have the RBs and Novarossi engines have a healthy respect for the Sportwerks .26v2. If you're looking for a powerhouse motor that won't kill your wallet that's the motor. Another is the SH ProSpec .28. I run that and it's amazing for the money.
I love my sportwerks engines
. Without a doubt they get you the best power for your money and they are very cheap to rebuild. I had a decent edge over a Novarossi P5 down the straight away with my Sportwerks .21 with just about the same low end power. The difference is the Nova will last 10+ U.S. gallons while my sportwerks will only last about 6. However a new piston and sleeve is only $50 for the sportwerks.
