I have a 90 dx crx thats not fuel injected and i want to drop in a jdm b16 that is fuel injected......would i be able to use a 91 si main harness and just pretty much transfer the si harness to replace the dx harness and have it all work or is that not possible??? I have the motor and the engine harness and both the dx and an si main harness


Wutta ya think????

Totaly possible, just do a search online and find a DPFI to MPFI pinouts.

Here this place has a ton of great info:

all 88-91 civics / crxs are fuel injected...there is just 2 types

dpfi (dual point) which only 2 injectors spray into the intake manifold itself (closer to the throttle body)

mpfi which 1 injector per cylinder (4 total) spray fuel immediately before the intake on the cylinder head)

mpfi > dpfi in power, efficiency

 

I second that.
Also, I don't believe 90 dx main harnesses will plug into 91 si engine harnesses(without some modification). You could try it, but chances are they are different and are gonna require modding to work.
