All motor Sohc build up
ok here is my SOHC All MTR set up:
d15b7 block bored 20 over with p29 20 over pistons
knife edged crank, balanced and blue printed
d16z6 head with p&p
Zex stage 2 cam with skunk2 cam gear
skunk2 valve springs, retainers, high compression valves
P&P intake manifold
Ported throttlebody to H22 butterfly specs
Full MSD ignition
shimmed VTEC
DC 2 piece ceramic 4-2-1 header
custom 5inch intake
ACT stage 1 clutch with 11.5lbs flywheel
ZC/Si/Dx/ Tranny with Lsd unit
Yield 12.26.1 compressions runnin on 114 octane
The motor is not tuned yet and is being broken in before a dyno session takes place. Positive comments welcome

how'd u come up with that c/r number? i thought that the d15's piston pin location would have placed the p29's much lower in the block thus resulting in a lower c/r?

Re: All motor Sohc build up (kadburry)
If you did not use VX 1.5 vtec-e rods in that d15b7 with the d16 pistons, then it was basically a waste of time, due to rod length/piston pin location. The d16 pistons will sit lower in the hole if they are 1.5 non vtec rods in a 1.5 block. Might wanna look into that. If you used some online compression calc like c speed or the sohc calc, they wont take this rod length difference into account and your numbers are false.
Liam821 (usually in the turbo forum) and his buddies had a project d15 drag car going. He ran into this problem. This is how i know of this first hand. Same set up as you with the vtec head. It mathematically makes sense also.
Good luck.

yea, it's around 10:1 with the dx rods. I got 14.3:1 using a z6 headgasket, and 13.7:1 using the b7 headgasket, I'm not sure which one you use with a mini-me. About 15:1 if you use the 2 layer y8 gasket.
I'm pretty sure my calculations are correct, but its late and I'm tired.

You mean oil pump?
How much money do you have into this setup?
