Heres what I'm thinking about. I'm going to be doing a TT rod + vitara piston build so I can up the power A LOT. I have two options that I'm looking at right now:

1) Rebuild D15B7 (300k miles) that I have sitting around

2) Do above ^^^ but my current Z6 head on the D15 bottom end

3) Source out a D16Z6 and then have it rebuilt


In your honest opinions what would be my best bet at making 300hp? Could I attain 300hp on a D15B7 TT vitara setup?


Currently running D16Z6 (soon to be boosted 3psi @ first with MBC to up to 7psi when I'm comfortable)

 

rebuild ur current z6.
if u need a running car, throw the b7 in there temporarily.

 

your a ------- genius! Why the ---- didn't I think of that ----? Thanks

 

Fjt sells d15 rods, there about 300 but there thick.

 

d15 rods for the d15b vtec, which are identical to d16 rods. b7 rods have 1.5 journals, d15b have 1.6 journals

 

I know a few months back fjt was trying to get rods for a usdm d15, did anyone hear word on if those are in or not?

 

still in the works. if it ever does happen, fjt is going to have a major niche in the market

 

Reason I sent FJT a few D15 OEM rods

 

Yeah rods for a d15b7 are hard to come by. BUT

I just had the idea....

What about B16A rods? it appears they are only .015" longer than D15b7 rods.... I'm going to play around with the compression calculator... I could be on to something.
