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.

boost it.

so what if it blows, you can pick up d15b7s for like 100 bucks

i need this car to get to work and back, if its just going to blow immediatly that would be very inconvenient regarding my work schedule...

With that turbo you should be fine.. Just remember, tuning is everything.. You can blow a b16 with that turbo and 3 psi or you can run over 10 psi with a T3 on a d15 and make it last forever..

I think the big issue, aside from tuning, is the mechanical strength of the rods.

i ran 6psi on my d15b7 for over a year.. Had 130k on it. Ran great and never acted up

They are really weak but again good tuning can get alot of power out of them..

tuning is key on any setup . . . be it NA or Forced Induction. If you run to lean well then you run into problems. Boost that motor and just spend a little time reading about fuel managment. Do things right and you'll be good
