quick Q about SOHC ZC into 90 si crx

[THEONE]

yeah the zc drops right in and since you have a si you need no harness. its just re pinning the harness on the distributor. you can even use you si ecu it works great.

The jdm d15 vtec is a strong motor, but its not any better than a D16z6. The HP numbers are the same but d15 vtec has a slightly more aggressive cam than the Z6 but the Z6 has a greater abundance of parts for high compression and cams.

In an EF i would do an A6 non vtec with Y8 head. (I believe the non vtec zc is the same as the A6.) The compression ratio will be 10.3:1 and the A6 distributer bolts/plugs right up with no modifications. Run a couple wires for VTEC to the ECU and you are done. If you are worried about an ECU get a JDM b16 PW0 or PR3 ecu and stay OBD-0. You could convert the car to OBD-1 but then you would have to buy the converssion harness ($100) plus a p28 ecu ($75-$100) verses a JDM b16 PW0 or PR3 ecu for $100.

I have an A6/Y8 in my 91 si and it is a Great build. I/H/E on the A6/Y8, with a light (30 minute) tune and you are running with B16's in EGs. And once again parts and modifications are so easy to find and are cheap. (A lot cheaper and easier to find than aftermarket parts for a Dohc ZC)


A Lightly Built D16 Will Rock A B16"s World For Half The Price!
