i just got a 90 hatch dx and im not familiar with them as i had a 99 civic. i want to do the dpfi swap to mpfi swap. is the d15b2 engine worth building up or what engine should i get to build up that will fit in the stock axles,mounts etc??
can someone give me a write up page for the dpfi to mpfi swap page i have looked but if anyone can find me a detailed swap page it would be greatly appreciated.

could i use any of the parts i already have-
rc 440 injectors were on my d16y8 with obd1 clips
p28 chipped
walbro 255l fuel pump in my 99 civic

best write-up out there. goodluck i had mine running in a week.

dunno about the rest of your questions though, i swapped mine from a 91 si d16a6.
