Civic EG

My friend had a d15b in his 99 ek civic he has ruined his engine and was thinking to buy a new d15b single or dual vtec we really dont know much and are short on cash our tuner recommended to get a Zc for the ek i wanted your opinion what should we buy?

Not sure how difficult it is to find motors over there but here in the us, the dohc zc is considered an obsolete, outdated motor. It's an obd0 engine- one of the last Honda motors I would swap into an obd2 ek. If you have a limited budget, I say stick with a sohc vtec d series. And maybe look for a new tuner

thanks alot sir!

Many engines are stamped ZC. The most widely known is the crappy OBD0 DOHC D series that was popular for putting into CRX's in the old days.

I had a ZC that was the JDM equivalent of a D16Z6. Slightly different cam profile and no port on the intake manifold for the purge solenoid.

There's also a ZC that is the equivalent of the D16Y8.

It would seem that the ZCs are all 1.6liter and the JDM D15Bs are 1.5.

so your recommendation is? if its the d16y8 equivalent one then i should go for it?

Yeah, an OBD2 equivalent makes the most sense. D15B or ZC. If it's a 3 stage VTEC, get the ECU specific to auto or manual transmission.

lol talk about old days I had 89 CRX DX with a ZC in it and i thought it was so fast but it was compared to the d16 that came in it that was rated at only 92HP the ZC put out 130 or so with a intake on it
