hey i just wanted to know what i need to do a b18a1 swap to my 1990 honda dx
first convert your dpfi (dual port fuel injection) dx to mpfi (multi port fuel injection)
your dx has 2 injectors and the b-series has 4
you will need an obd0 pr4 ecu, shortened integra shift linkage or buy one made specificly for the swap, check out hasport or innovative mounts, they also have motor mounts designed for this swap
you need an injector resistor box also for the dpfi-mpfi swap
use the engine harness from your dx, you will need to swap 2 wires on the throttle position sensor connector, check out the dpfi-mpfi write up under swap articles on the honda swap front page
you also need DA integra axles
i haven't started my swap yet, still collecting the bits i need and working through the poor mans rebuild on my motor, but i think thats pretty much it.
btw if you get an SI model you won't need to do the dpfi-mpfi conversion or find an injector resistor b/c the SI is mpfi, making the swap a bolt in affair...
