since i can not find a ZC SOHC engine & trans im thinking ill settle with the D15B VTEC SOHC engine. is the D15 swap just like the ZC swap ? from what i found on this forum is that my D16 in my 92 SI is the same engine as the ZC and makes the swap very simple. is it gonna be the same with the D15 ???



thanks

yeah the d15b should swap right in there. im planning on the same swap too.

I just put a JDM D15b in my 93 Si hatch.

I used my old Z6 intake manifold since it is a bit different and I swapped over the vtec switch since the JDM motors dont have them.

^^^^^ so how did it work out ?? anything i should look out for ? FYI im more of a magazine mechanic lol i can do some things... but my buddy whos been a mechanic for 10+ years and workin on cars for who knows how long will be doing most of the work but any info i can give him to make things go smoothly would be great


thanks

its pretty much the same motor. you will want to use your z6 intake manifold and vtec switch. Mine had a bad dizzy so i used my old one too.

other than that, its all good.

you have to switch out the vtec switch (solenoid ? same thing right ?)

so that means i gotta go to the junkyard and find one cuz mines just a stock 1.5 no vtec

not the whole thing, just the green switch that goes into it.

good stuff man. i just ordered the engine today and should have it in 7 days. i hope it all goes well

yes, if your vtec solenoid looks like this, you will need to change it.

no oil pressure sensor (green connector)
the p08 ecu does not care about oil pressure (for vtec).

You still dont have to change the whole thing. I didnt and it works just fine. I just put the switch on the new unit. just screws in.

what header can i go with? i have a Megan header for my D16 enginge so is that gonna fit my D15 ?

yes it will fit.

i sold my y8 and bought a d15b with a ported and polished y8 head and si tranny its badass i broke off a 99 si and a ls-vtec crx....i got the motor and a p28 from my buddy for only $570
