do i need a new ecu to put a d16z6 into a stock 91 crx dx, if so, which ones will work?

yes i searched

edit: i kno the stock dx tranny will work, but should i consider pickin up a different one? if so, what kind. bear in mind i'm poor

 

you'll have to convert to MPFI (4 injectors) first then you can use:

These will work but will have to be used in correlation with a vtec controller:
PR2 1988-1991 ZC
PM8 1988-1991 CRX HF (don't use this one)
PM6 1988-1991 Civic/CRX SOHC Si
PM7 1988-1991 ZC
PG6 1988-1989 Integra, All Models
PR4 1990-1991 Integra LS/GS
These are the only two that will activate vtec through the ecu without aid of a vtec controller:
PW0 1989-1991 Civic/CRX SiR (modified to remove 2nd O2 and knock sensor)
PR3 1989-1991 Integra XSi/RSi (modified to remove 2nd O2 and knock sensor, may work never tried)

Or convert to OBD1 via a harness, obd1 injectors, obd1 distributor and use:
P28 1992-1995 Civic EX/Si / del Sol Si
p28 1992-1995 Del Sol Si/Civic Hatchback Si/ Civic EX

Currently i am using a PM6 with a fields vtec controller with no problems. I've used the PR3 with the mugen program to eliminate 2nd O2 and knock sensor it ran the best. but i'm selling the controller and possible converting back to SOHC non-vtec, maybe if i get bored enough
