I have a 1991 EF four speed hatch. I think it's an HF. What all do i need to swap an LS or B20? computer, shift linkages, harness, motor mounts, cv's etc.....?

 

First the HF was only a CRX. You have what's known as the STD. You would need to put it in, and have the corresponding ecu, your stock harness can work, but you also need to convert to MPFI. Mounts, linkage, and axles. Check out the faq, it's like beating a dead horse back alive.

 

would it be easier to swap a d16 or should i just look for an si instead. I dont have the "STD" yet im still trying to sell my '98 LS teg.

 

i have an std.......

 

I have the same 1991 ef hatch and mine is a 5 speed is that rare or some thing cuz i see alot of them with 4 speeds

 

They came from the factory like that, more than likely yours was swapped to a 5 speed.

 

well thats cool thx man.

 

Im pretty sure the STD model would need teg, si or ex knuckles in order to accept b-series axles

 

actually EF DX and Si knuckles work with B-series axles.
