Just wondering if anyone has info on a d15 build with y8 head with integra pistons.

MIDNIGHT

the teg pitson will not work in the d15 due to wrist pin location. the y8 head with a stock d15 piston setup is the way to go. i had a stock d15 with the 6g nonvtec y7 head(wich is for sale) and it took zc powed crx all day long. its a great motor.

How much hp did you have on your d15 like 140?

WAFFLES

he never dynoed or anything, it was all buttdyno. It was a nice motor though.

blackEF

so you have a motor better than the zc for under about 400 bucks?

WAFFLES

midnight has all sorts of d series **** laying around his garage. **** he has hella ZC parts for sale I believe.

blackEF

so won't zc pistons work? what results would that make?

MIDNIGHT

i think so. and you can still get parts for it. unlike the zc. dont get me wrong i loved my zc but i was just surprized at the d15 power i got. this was the setup
d15 shorty
d16y7 non vtec head
clutchmaster stage one
d16a6 intake mani
d16y8 exaust mani with b20 down pipe
zcsi tranny
home made cai
thats it
i used the zc tranny on my d16z6/zc and the d15 and i still think the d15 was just as good as all of those. IMO

blackEF

what ecu did you use?

MIDNIGHT

from what mista bones has said the piston set realy low in the cylinder and does little to nothing for comprision. and a flat top piston will always have a lower chance of ditonation campared to a dome

MIDNIGHT

4g si ecu

So the y7 head is just like the a6 with higher compression??

MIDNIGHT

yes and it flows more and has larger valves than the a6.

blackEF

So you don't have to wire for vtec with the y7 so would it be worth it to get the y8 head if its not much more of a hassle??

MIDNIGHT

the y8 will give you a higher comp ratio than the y7 due to the square chambers and the vtec will give you a better top end. i just like the simple non vtec approch.

blackEF

true that. So would the HF block be fine to use?

MIDNIGHT

i guees i alway toss them in the trash our use them as a backup motor. but i would think it would be the same as a dx motor just with 2 valves reliefs on the piston wich mean you gotta swap out piston before you can put a 16v head on

right now, i'm in the process of finishing my project. i got the d15 + y8 head (P&P, 3 angle vavle job, .40" milled head, y8 headgasket, d16a6 intake man+TB (match ported to head, CAI, Chikara torque step headers) i got everything for super cheap, and did all the machining(vavles,mill,P&P) myself at school, i'm pretty sure the d15 mini me will smoke alot of cars out there, problem is right now i got an automatic, but have the tranny ready to swap too, i'll let u know how it works out.
