91 ef swap help

[geedog66]

ok im gettin a 91 dx hatch and im doin a b18a1 swap in it... now my question is what wiring would be easier 1.. putting the dash and engine wiring out of my 91 civic si or 2... taking the dash and engine wiring out of my 91 integra... and input would help both my donor cars are complete

um.. just do the mpfi swap, witch is about 7 wires, and everything else plugs right in

Or why not put the LS in the Si?

since you have access to it, just swap the entire cabin and engine harness from the si into your dx.

well my si has tons of rust in the back end of the car.. i kind of want to put the integra dash in my dx since i got to take the dash out anyway... has anyone done the dash swap?

 

[D16SiHatch]

not that i've ever seen or heard of. probably a reason for that i would assume lol

lol found this thread right after i made the same one : p

im just starting a b18a1 swap into a 1990 dx but i dont have any si wiring, im thinking it would be less complicated wiring wise to install the body harness aswell and the engine harness from the integra which would hopefully eliminate re pinning of the ecu contacts, the only wiring i forsee as of now is lighting sockets and heater fan connectors... thoughts anyone

i guess the main problem ill have by swapin the dash is the rest of the harness plugin in the dash meaning goin to the back of the car and goin to the head lights.. im surprised no one has done this swap before...

The dpfi to mpfi wiring is pretty easy, there are tons of good write-ups floating around.

 

[EFDX]

is your b18a1 obd0 or obd1?

 

[geedog66]

obd0
