- Fri Aug 01, 2008 7:21 pm #64227 Ok I got a D15b2 with a MPFI swap. I have to rebuild the motor cuz it´s smoking bad. So I might as well put some forged rods on it and some NA Foged pistons. But I´ve had no luck finding these parts for it. I´ve heard that D16 rods and pistons fit on it no problem. That I just have to grind off some of the bottom cylinder walls to clear the rods. I dont want to swap blocks or nothing cuz here in Brazil it´s illegal and i can lose the car. Plus I´ve only got $1100 to spend on parts. What are your sugestion guys?

- Fri Aug 01, 2008 10:24 pm #64241 The D16z6 has a longer stroke, so the rods won't be a direct swap. I'm not 100% sure a D16 piston will bolt to a D15 rod either.

Are you planning on putting a lot of boost into the motor? If not, forged internals are overkill for a daily driven motor.

Suzuki Vitara pistons may also be another option if you want to save a little cash, I believe they are 75.5mm, so you would need to bore your sleeves .020.

Do Not PM me your technical questions. Post them in the forum!

d16 rods have journals that are too big for the d15 crank.
fj distributors has a kit for high compression all motor

i think they also have i beam (rod) for d15, certainly worth asking about.
