JDM D15b Vtec and boost.

Anyone know the compression of the D15b Vtec ? It't basically a D16z6, right ? So it should take the boost pretty well? Does it have decent sized rods ? Use the P28 ECU for this right ? Trying to decide to get a d16z6 or the D15b. I'm thinking mroe towards the D15b due to the fact that it has lower miles on it, that is if i actaully get one with the 40k miles that they claim they have.

D15B comp. ratio is 9.3:1 Use a P28 chipped. The rods are pencil sized like most D15's, just don't hit it to hard and it will be fine.

d15b's love boost, and they're cheaper and less miles than any z6 you'll find

they are thicker than d15s and have a larger big end, they are similar to z6 rods. but i wont fuel that arguement anymore than it already is even though i have the pics and measurements to prove it

And stock Z6 rods are pencil like too. We all know d-rods are weak, no matter what motor. Keep it under 10psi, tune it well and happy boosting.

I think the most i'll run is 7 psi on a 14b. So i should be okay. I'll get a wideband and just read up on the Uberdata forum and see what kinda tune that gets me.
