i was wondering if there is any other kind or pistons and rods (stock) that i can put in a d15b7 im wanting to boost it a little bit just for a little more power for right now probably abuot 5 or 6 psi. (i know this should probably belong in the f.i. forum but it will be there to i just figured there should be somebody on the all motor forum that knows something about this.) thanks in advance.

 

That motors a bit of an oddball. I think the rod length and the compression height of the pistons are different than the other D series stuff, but im not positive.
