Id like to start gathering parts and ideas for turbo charging the 327 in my fiero. i just want a small amount of boost, but the first problem i find is that the cr may be high at 10.25:1 with iron heads. but i was wondering that rather than replacing the heads and pistons that a long duration cam with cool plugs and 93 octain i might be able to tame the detonation. the engine has forged pistons, ported fuelie heads with roller rockers and a small cam for now. this is just an idea so all suggestions are welcome i dont even kno if this can be done with minimal sapporting mods thanx guys.
