Turbo's for the street

[deuce_454]

not to hijack... but the question has been haunting me... what size turbos to mount on an ls1, and i dont want 1400Hp, but somthing realistic... 650 rwHp?? or that teritory.. we have 95 octane available here, and the engine is an ls1, 8:1 comp, good heads.. dart? and a good intake.. air/air intercooler..

is it worth going ball bearing, they are more expensive and do not come with a warranty...
