What would be a good compresion for all motor( no turbo) with nitrous(maybe)... 8:5 10:5 or 12:5 i want to put down as much power as i can without a turbo HEHE

if you have mad tuning skills go with the 12.5:1 otherwise go with the 10.5:1.

I'd say 10.5 to 1 compression will give you more of a "safety factor" when tuning, especially with nitrous.

Yes I concur, 10.5:1 would be a nice way to go. And as always, it's all in the tuning.
