you can either convert to mpfi or just get a harness for a 90-91 si hatch and with the conversion harness you'll need to wire up a 4 wire o2.

No you cant just use a MPFI harness you have to convert your DPFI to MPFI and then get a jumper harness for the obd0-obd1 swap.

he has a std model with a 4 speed and the same hubs as a hf crx so i would recomend swapping hubs although i have heard that you can get away using hybrid hf/si axels
