Re: Swaping jdm d15b in to ef hatch not si
 

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.

i cant use an 88 crx si harrness?

Re: Swaping jdm d15b in to ef hatch not si
 

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.

you need si hubs/spindles

i dont think so not on 90-91's or maybe was that only crx's ???

Re: Swaping jdm d15b in to ef hatch not si
 

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

the hf axles fit an si tranny. they will work if they ar in good condition.
