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.:D
 
well the d15b2 motor has a different harness because its dpfi and not mpfi like the si motor.also the ecu is different, but other than that its perty much a direct swap
 
so i have an si motor... does that mean the whole car is an si? maybe that motor was swapped in. i dont see any SI decals.

here is info from wikipedia

according to the above, my car originally had a d15b2. am i right? so... if my car is a DX... with a d16a6, im assuming that it was swapped in.

confused. :( anywayssssss. this would also mean that i have an si harness... so BASICALLY... i would just need to get the original parts (motor, ecu, engine harness) and BAM. done, no?
 
well does your car have a sun roof ?
 
take the intake manifold, injectors, etc. along with the distributor from the D16A6 and install them on the D15B2 and drop it in - just like doing a DPFI to MPFI swap, except the wiring is already done
 
dont the b2's have a graphite head gasket?
I though it was called metal composite. Anyway the A6s have the same gasket. Most '92 and up use a stainless MLS gasket, it lasts longer if you deck(s) are nice and flat.
