iv been searching about this, i only swapped a ls into my da before, when it comes to wiring i dont know what to do, i dont even know how to converte to odb1 , i am thinking to do a h2b, i already know everything about the swap except for the wiring and ecu

here is my plan

jdm h22a , qsd kit, stock ls tranny. i am thinking to keep all the emisson stuffs to make it smog legal.

do i need a manual 92-95 prelude ecu? so can i just unplug the old one from my 90 odb0 teg and plug whichever ecu i need onto the old ecu harness?

would it make a different if i have a 92-93 odb1?

do i use the old engine harness for the h22 block?

what do i do for distributor, alternator, fuel injectors, and other sensors?

i am so confused , pls give me a hand


thanks guys

 

ok , i just did more researching , from reading the honda swap book, i learnd a lil about odb, so an odb1 ecu will plug right into a 92-93 teg, a jumper harness is needed when using an odb1 ecu to a 90-91 odb0 teg

 

if u can find a 92-93 gsr harness.. you wont have to wire anything.. just get a resisitor box and a p13 ecu

 

as far as i remember obd0 and 1 use all the same sensors and stuff on the engine side maybe some different type plugs you might have to splice some them. main thing is getting a jumper harness to run a obd1 ecu with a 90-91 teg. if you haven't yet go onto g2ic.com and read some of their guides and teg tips. someone wrote one for swapping in a h22. the h22 basically wires up the same as a b18 obd1 engine youll just have to wire up vtec and extend the alternator wiring.
