what all do i need to do a complete swap from b17 gsr engine into a crx hf?? well it be a plug and play or do i need motor mounts?? and well the wires need to be re-routed?? has anyone done this swap and know the 1/4 time?

jdm zc is too old of an engine, and jdm b16's wont pass emissions. i was thinking bout swapping b17 gsr, hoping to pass emissions? what route should i go?

ive seen zc motors and b16a into crx's but only running low15's with zc and low 14's with b16's. what bout b17's!

Dropping a B17A engine into a rex is no different than dropping a B16A in. You'll still do the same routine as droppping a B16A in, meaning you'll need to get some kinda of bolt in kit + shift linkage kit (HASPORT plug).

You'll wanna get an 89-91 B16A ignition system (distributor, injectors, PR3 ecu) for a hassle free install....(b17a's are obd1-wire type equipped and will NOT plug n' play into your CRX's wiring/ignition system). You'll have to wire up the vtec components of course. You can reuse the B17A axle set if you get them with your motor otherwise you need 90-93 integra axles. You can reuse your CRX HF engine harness on the B17 engine if you get the 89-91 B16A ignition components i mentioned already.

.....since you want to pass emissions, you'll need to run the OBD1 smog equipment on your car, have fun doin that. I can't tech support ya there.

If you build up a B17A with high compression pistons, some decent camshafts, reprogrammed ecu, and some dyno time + some other misc. crap you can run a way good time in your crx.....low 13's perhaps. It's all up to you & your wallet tho.

Thanks for the advise katman! I'll ask more details with Larry Jr. at ImportAutoSalvage when i'm actually going to do the swap.
