wut up ppl. ok i gotta 93 civic hb with a gsr motor. right now i got a intake, catback exhaust and header. the parts i have but havent installed yet r forged low comp pistons (8.5:1), forged rods, copper gasket, boost timing master by msd, wires, colder plugs, fuel pump regulator and engine management system by aem. these will all be taken to a shop to be installed dyno tuned when i make up my mind, sc or turbo. is an 8.5:1 comp low enough to run 14psi safely on this gsr motor? also the car will be daily driven and on pump gas so the boost will be set at around 4-7psi. will the b18c1 with these mods i listed be enough to protect my engine? the main reason i wanna go turbo is because i will have the ability to lower boost at any time with the turn of a ****. this means ill put a lot less stress on then engine, right? o yea will i have to worry about detonation at 14psi with all these mods? ive been to like 5 diff fourms and these r the only questions on my mind right now. thanks.

 

i'd be more worried about making power at 4psi on 8.5:1 pistons.... maybe a 20 horse gain?

9-9.5 is average, 10 is fine, 10.5+ you start getting on the hard tuning/high risk side of things... but 8.5 is really low. its going to dog like a bitch.
