Imprezor

I'm thinking of rebuilding my D15B8. I'll blueprint the engine and I'll use a SOHC VTEC head, d16z6 stock intake & exhaust (by now) manifold. The plan is turbo, in about 4 months. So I was wondering about how strong are these D15 rods, compared to D16's, for example. I have here B18B's stock rods, but I've heard they're shorter than my D15's??? If that's so, they won't work on my setup will they?

About pistons. Are they the same of a D16? (talking about resistance).

I really need help on this 'cause I was ALSO thinking of boring the cylinders (not too much, just to straight'em up) and buying new pistons. I've read something about VITARA pistons. What about them? What other stock honda pistons would you recomend me for 6-8 psi setup?

Really need the help

PD: I don't have the money for forged internals
