I have some TT rods and vitara pistons. Would these fit in my d15b? I've read on another forum about this, but I figured the d15b block is too short, then again i donno.

the pistons will stick up .018-.020", ok if your running a open chamber head like Z6 or A6

Mista,

Isnt the d15b head the same cast as the z6 head? So that puts me on the safe side. I tried using a calculator to check the static compression, without luck. Do have any idea what kinda compression that would make?

Thanks

Here is my calculation which could be wrong

d15 has a 75.00 x 84.5 bore/stroke
ccv 34.60cc
Piston Dome Displacement for vitaras = -12cc

and the compression ratio comes out to 8.35:1 Does this sound right?

No it is going to be a little higher than 9:1.

Bone1

nope, below 9:1

If stock is 9.2:1 and your adding a dish, definitly gonna drop a good amount.........

oh snap......I even got pics

Ya if the D15B was 9.2:1 in stock form. It is actually closer to 9.6:1. The P08 pistons have less of a dish than P28s.

Vitaras have a higher comp height too, so some of that extra dish is being taken away.


I run LS/Vitaras in my D15B.

sounds like my build.
