I have a ef sedan shell I bought it running but dropped engine for a swap so I went ahead an bought a 94 acura Integra sedan as,a donor car I know u need the mounts an obd0 to obd1 conversion an also the dpfi to mpfi but other then that is there anything else I would need my Integra is currently running as well...

 

Shift linkage and depending on your exhaust situation you may need an extension.

 

B series swap mounts, 90-93 integra rear t bracket, hydro clutch conversion (if using hydro trans), 4 wire O2, distributor adapter for whatevr OBD you will be using

 

And possibly axles. Not sure if the integra axles will work or not

 

This has probably been done like a million times, search.

What do you means by my exhaust situation??what is the t bracket for??

 

those will work. my axles and intermediate shaft are from a '96 Integra
