what do need to put a 2.0 out of a 89 into a 90 with the 2.01 , will the intake and exhaust bolt up

[sleepyH22]

i think they will...i had it done on my 3rd gens but that was a while back and i cant remember for sure but i am pretty sure they will.

its pretty much a perfect drop-in. the only difference is the b21 has a 4-wire O2 and the b20 has 2 single wire O2s. id use the b21 intake manifold if you can. not sure about the ecu though cause the b21 has an obd1 ecu and the b20 is obdo

i think that you can use the same ecu if you use the same intake manifold, etc.
