i bought a 89 civic hatch from a friend. his motor overheated. i guess cuz oh his radiator. bought it for $200. i have an oportunity to buy a d15b2 for $100. i was wondering if this motor will swap right in? any changes to the harness? ive been searching... but im new to civics and sohc. i mostly mess with integras and b series. ive read something abot mpfi and dpfi conversions. i hope this isnt necessary in my case. is there anything else i need to buy? new ecu? i think the b16a6 has the pm6, and ive read i need the pm5 or 4. so much info dont know whats reliable info. someone help. bottom line is: i have a chance to buy the d15b2... and replace my busted d16a6... should i just do it? i just want to get this car running. if getting this motor working right in my 89 civic dx will be somewhat easy and inexpensive, ill go for it.
