I have made plans for my boosted D15B. The plans were to do my edelbrock intake manifold, then save for my internals. Cam, pistons, connecting rods, racing crank (if they make them?), and any other internal mods I could find. After that or while I was doing that I want to upgrade to the 16G Evo III Turbo. I was hoping to do that and run 20psi.
Now I'm hearing they don't make good aftermarket pistons and connecting rods for d15's. Do they make these parts and if so where could I find them?
I'd really love to build my D-Series without having to swap a B16 or something.
Can I do this still? If I find somewhere I would be getting it ported and polished aswell.

 

tuner toyz rods and vitara pistons good for 400hp

 

^ +1 and you dont need a race crank, the stock crank is forged and zero balanced. Should be good for 600whp

 

www.crower.com has your d15 rods

 

Couldn't find em. They only have d16 series advertised in there.

 

I heard the pistons don't fit right and you need to get your cylinders bored? Is that true or do they make the right ones that I could match up with connecting rods?

 

I found these ones, is 75mm right? http://cgi.ebay.com/ebaymotors/Vitar...spagenameZWDVW
The other ones I found said they worked on a d15 with a z6 head but you would need a bigger head gasket.
Will the 75mm fit right?
Do they make forged pistons for the D15B? I'd like to get the best quality stuff if it's possible.

 

75mm is right. The diff between the Z6 and D15B is the stroke. D15B is 84.5mm and the Z6 is 90mm-giving it the .1 litres more displacement than the D15B

 

Then how does it make sense the 75.5 mm fits the z6, and the 75mm fits the d15b. Thats only .5mm, but you said the size difference is more like 5mm.

 

double post sorry
