my friend just bought a 95 civic DX with a d15b8 in it. according to my research that engine only came in the cx and its an 8 valve. Im assumin sum1 swaped engines because it should have a d15b7(16 valve). well this engine has a blown head gasket and warped head so im just gonna replace it for him. But my question is does it matter wich one i put back in there? are all the plugs gonna be the same for the harnes? any other problems i might run in to?

It doesn't matter what motor you put in there. Just as long as you have the same engine harness meaning obd1 then it'll all plug in and just go in

2nd that

Check out tiger japan they are having a blow out on zc and dohc zc. My friend just got 2 zc's for 900 with trannys

The ECU will matter. You'll need the ECU for the engine you're using. But you may already have a P06 (D15B7 ECU) in there.

thanx u all and i will be chekin out the ecu to make sure wich one it is cuz i prefer to put back the d15y7 as it has a lil more power

Ecu won't matter eather one will run,

But if your looking for power then why put another 1.5 in there???

CivicSpoon

Yeah either one will run and start the car, but it definitely matters. The B8 is an 8-valve engine, where the B7 is a 16-valve engine. Using a P06 on a D15B8 is going to run very rich, and eventually cause damage to the engine. Using a P05 (D15B8 ECU) on a D15B7 will cause it to run very lean, which will eventually cause damage to the engine.

They are probably just putting in another 1.5L because they are inexpensive engines, and anything is better than the D15B8. I own a CX, and I can say from experience that the D15B8 is laughably gutless.
