how strong are d15's?
hey guys im curious, how strong are d15 motors? im guessing a bit weaker than d16's but i see guys running some good boost on the jdm d15 motors. Im thinking i might use my spare d15 just as a test motor, but i wont if it's gonna pop immediatly, thats not worth my time. The motor is a 160K mile d15b7 it always ran very strong and never burned or leaked anything. I would run the IHI rhb5 turbo at stock 8lb wastegate, hf mani, walbro pump, 450cc injectors, afc , small fmic, some sort of a turboedit map for my chipped ecu, maby a little dyno tuning.
with no problems. stock timing

Re:how strong are d15's?
it depends on a lot of factors, so a definate number of miles can be given before it 'pops'. If it's a spare I say go for it, it'll give you some tuning experience... so ditch the hack and go with a chipped ecu, when the d15 does go You'll have a good grasp on street tuning and what not to do.

ran a D15B2 with MPFI conversion for 2 month's at 14 psi...with the hack on a PM7 ZC ecu...running pretty rich.
Toyota CT20 turbo AR .42 comp...compressor was as big as a T3 AR .42 I measured it and had it side to side with a T3...

Re:how strong are d15's?
i had a d15b7 in my 95 dx. didnt know what was done to it but it had major *****. kept up with a 99 si until mid 3rd gear. i boosted the b7 with the rhb5 and reached full boost around 3500rpms. then i got turbo happy and messed around with a mbc and cranked it up toi 15psi (accidently) and smashed 1st gear and 2nd gear then 3rd gear kaboom!
