Hey guys I keep hearing that ls is more turbo friendly cause the comp. ratio, but would it be bad to turbo a gsr or is it better to go naturally aspirated and throw some nitrous in it?

You can just get the GReddy Kit, its carb legal. Or just throw in some JE 8.5-9.0's. Nitrous is forced induction, but yeah I dont think the C/R plays too big a part whether its safe or not. If you get a nitrous kit, just be careful and do what the manufacturer recommends.

explain je 8.5- 9.0
