if your comp is to low your air/fuel mixture will not ignite, personal i wouldn't use any standard gem piston in it if u are planing on running any resonalbe amount of boost, u need 2 get hardened or forged pistons to handle boost pressure |

remember, the lower your comp is, the crappier it will go off boost. so if your turbo spools up late, then you'll be a snail until you hit some boost. |
