what exactly is needed for an ea81 spfi swap??


Recommended Posts

i found a 92 loyale fwd auto at my local yard with a great spfi setup on it. i`m pondering on doing the swap onto my ea81 hatch, so i was just wondering, what exactly do i need, before i miss something and the car gets crushed:lol: this is what i know....

 

intake with all the goodies, disty, ecu, wiring harness, fuel pump, alt., maf, what else?

 

also, how hard is it to add the ea81 timing gear to the ea82 disty? is welding required or can i rig it with something else?

Intake and all attached bits, disty, ECU, Complete forward wireing harness and the relays and fuse panel and junk that's attached to it under the dash (by FAR the hardest to pull), and the disty. Don't need the alt - EA81/82 are pretty much the same (50/55 amp).

 

As for attaching the gear - Some have welded it - I lined it up very carefully and drilled a new pin hole with my $40 harbor frieght drill press. The bit I used was very slightly larger than the original hole which worked out good as the new hole in the disty and the gear (I drilled through both at the same time) were the same size. I took the original spring roll pin and used a large flat wood chisel with a sharp edge to drive the roll pin apart a little a make it big enough to fit snug in the new hole. Then you have to cut off one mounting tab (I used a band saw), and remove part of the metal plate covering the wiring on the bottom of the disty.

 

That's as far as I've got so far - had a little issue with brake shoes on my sedan so had to unexpectedly drive my EA81 for a few days before I had time to fix the brakes. I'm actually planning to work on it more today.

Ancient thread, but when drilling for the ea81 gear, what would be the peferct orientation for the gear on the shaft? Like, everyone says very carefully. But ive read abput others always being 1/2 tooth off. Thanks for the input
