Ok I bought a 91 hatch awhile back. Today I picked up a 91 B18A, tanny, ECU. Got mounts and shifter linkage on it's way. I figure I'll pick a header up befor the swap. OK, on the axles use 90-91 ls axles with the dust shields and the dust shields on the hub bearing knocked off? I'm going to go ahead and pick up a jim fab front crossmember, but, It'll be after the install. So, I'll need to notch the stock one till then? Then the denting the left frame rail, is there a science to this or just trail and error? Does anyone have a pic of theirs I could see? I know I'll have to do the dpfi to mpfi wiring. Is there anything else I should be aware of?

Thanks

 

hey this may help:

1. you need an injector resistor from a 88-91 Si model.
2. consider get the DPFI to MPFI conversion harness from Hasport
3. rear crossmember needs to be adjusted slightly to fit rear engine bracket

and for future reference, ALWAYS do a SEARCH first before asking a question. you'll find endless info under the search area, some info is archived too.

otherwise the guys here may rip into you and make you feel kinda stupid. or very stupid. so please search dude.
