MPFI swap on 4-Spd STD Hatch

Which ECU can you use if you do an MPFI swap on a 4-speed STD Civic HB (1991)?

Thanks

pm6

Will the original air intake still fit?

just got done with the mpfi swap on my std. it makes a pretty good difference. anyways you can use any obd0 mpfi ecu si(pm6) hf(pm8 i think) the best would probably be a pm6 but there are other options. also yes your stock airbox should work because the tb placement on the mpfi mani. is really close to the inlet of the air chamber of the dpfi mani.

I'll sell ya a PM8 for a good price, PM me or email me at [email protected]. I can get you the injectors and connectors too.
