Just curious, what motors can directly bolt into a first gen rex with no mount kit?
hoping to get a swap set-up for this lil bastige

 

dohc engine( can't remember engine code offhand) out of the 1st generation integra. It will bolt in without a mount kit.

 

the one everyone thinks is a dohc zc? hehe. I've heard of that one fitting before, thanks.

 

It depends on what country you're in, so first please add your "Location" to your profile and we can give you better advice. It also depends on if your CRX is carbed or fuel injected. If you're carbed then you will need to either do an mpfi swap, or convert the swapped engine to carbs. If you're in the US the easiest bolt-in swap is a D16A1 engine from an 86-87 integra. You only need to slightly modify one engine mount (hacksaw a chunk out of it) and run a couple of wires. You will also need the teg tranny/axles/hubs/knuckles/front suspension/ecu etc. The D16A1 from an 88-89 integra will bolt in the same but it requires more wiring because it is electronic advance ignition instead of vacuum advance ignition like the 86-87 teg & 87 CRX. The best place for info on 1g CRXs/3g Civics is http://www.redpepperracing.com , but PLEASE search and read the FAQ thoroughly before you start asking questions.
