i have a spare d15b7 just sitting around and i was thinking about building a mini-me turbo motor. i was hoping to squeeze 20 psi of boost into it. is this worth building or should i just get a complete d16z6 and build it?

the d15b7 bottom end is not as strong as a d16z6 or d16a6. the rods are tiny. I'd go with a z6 instead for that kind of boost

i kinda figured it would throw a rod. wanna buy a b7? lol

The D16 bottom end is not as strong as the D15 one.
Bore to stroke ratio is much better in the D15, making it a better motor.

20psi on either one is going to 'throw a rod' though... get Vitara pistons and Eagle rods for the D15, and thén put 20psi on 'em.
The Vitara pistons will decrease compression, but the mini-me raises it again, so that's a good thing
So throw in a few more dollars, and have a fairly reliable (still a D...) setup making nice numbers (for a D )

yeah i am definately planning on a full build. nothing stock will hold 20psi. and i was planning on getting a hondata s300 ecu which i believe can save up to 3 boost tunes, so i am getting a tune for 10psi,15psi, and 20psi. then i will still get some kind of gas mileage running 10 for dd.

stefan, He was asking about the d15b7, it soulds like you're talking about the jdm D15B.

Nope, I have no experience with the D15B at all.
I do have experience with sohc D16Z2 and dohc D16Z5, the D15B2 and D15B7.
What part of my reply made you think that?

because you said The D16 bottom end is not as strong as the D15 one.

But if you compare the rods, the D15b7 looks like a pencil. The z6 isnt a whole lot bigger...

do you plan to sleeve your block, or run a block guard?

from what i've read, right around 10psi the stock sleeves start to "float". (move around) which ends in ka-booom after a while.

im gonna run a block guard, re-sleeving is to expensive.

Sig too big.
