The best BOOST or all around motor is the GSR, HANDS DOWN. heres why:
Thicker ringlands that can handle 300whp
Great turbo motor since its a 1.8l
Decent compression (10:1)
Great NA candidate with bolts you can make 180whp.
B16s WILL NOT LAST past 250whp. their Ringlands are WEAK an THINNER, they break an crumble under boost. Anything past 230whp on a b16 on your on borrowed time.
We have gotten 270whp out of a bone stock GSR(stickys) and it popped a headgasket. I have seen GSRs make 300+whp on HT but anyone that thinks its reliable an feasible for every day, i hve a dyno here that will totally disagree with you.
For safety an reliability, a GSR can stay between 230-280whp. anything over that an your on borrowed time.
as far as the heads go, in a turbo application, it doesnt matter considering stock vtec heads (stock cams, springs, ret, valves, ports) make 450-630whp. I have dynoes to prove it.
An a CONSERVATIVE tune would not be anywhere near 300whp. thats a VERY aggressive tune. Id also like to see the 395whp@12psi on a STOCK GSR motor, that on race gas i assume? stock intake manifold? full race kit?
detonation will destroy cast pistons, thats why i dont think its wise to keep it at that boost level
Bottom line: depending on what turbo your running (i wouldnt use anything over a T3 super 60 on a STOCK INTERNALS MOTOR) 10-12psi is the max iuf you dont want it to grenade
