I have a set of ZC cams if you're interested. They are JDM so you might fit in better at Honda-Tech with them.

So your running Crower I-beam D15 rods?

Pretty interesting setup, I had a zc head all mocked up on a D15b2 shortblock, I thought for sure by boring out the 2 head bolt holes it would cut into a coolant passage on the head. Guess not?!..

Cool setup, and welcome to HMT

baseballinmyass

no because if you bore it out more than a 1/32" you did too much. if you use arp head studs you can guide the head over the studs and all the way down.

robs99si

that's good setup. those dick heads at ht will bash anything that's isn't a top brand kit.

baseballinmyass

oh by the way you only need to bore out one hole in the top left hand corner. the center top bolt you need to tap and redrill to 10x1.25 and use the bolt from the zc, because there is a platform in the haed that sticks up about a 1/2" higher than the d 15 head studs.

Which obd1 ecu are you using to run uberdata and what did you use for a conversion harness?

Spenser

you mean d16a1 head on a d15 block :P

tranceminister

Haha this is funny. Not 1 complaint here at HMT yet. You've got a nice little project there man and there was probably quite a bit of time/thinking that went on to accomplish it. So it's about time you received some recognition.

Very intresting now watch though a million questions on putting dohc zc heads on d15

Semnos

D16A1 is almost the same as a ZC...only different cams and ecu i guess..
1st gen CRX's from '87 over here comes tock with a ZC1 brown-top...it's looks the same as a D16A1....and the ecu is chippable...just can't control ignition...

Who said there is no aftermarket rod's for D15's??
Crower makes them :P

Nice setup man...and I was surprised it was in a EG and I was more surprised that it had a D15 block with a ZC head on it.
I have 2 D15 block's here and 2 ZC1'a and a D16Z5 ('92 ZC engine from the CRX...they sold the crx and EF civic in '92 also over here)

So how much did you drill the top left hole??
