Hi, my personal EJ swap project keeps on getting downgraded, but I am actually gonna do it so I guess that's all that matters... what started as EJ22 +5 spd D/R in my hatch has turned into EJ18 + regular 4spd D/R. My plan now is to get it going and upgrade later...but anyway my question is: does anyone know if the EA81 Flywheel will work with the EJ18? The hatch is an 88 so I'm pretty sure it is the bigger of the two EA81 flywheel varieties (clutch measures approx. 9") Of course I know about the bolt hole milling necessary to match up the EA82 flywheel to the EJ series motor. Would it most likely be the same deal for my flywheel?

I guess I will be finding the answer for myself when I pull the EJ motor (soon) but a little heads-up would be good it terms of procuring necessary parts. Also, does anyone know of any better clutch/pressure plate options than OEM for that tranny that might help with the extra HP?

Smaller EA81 flywheel is 8", larger is 8-7/8"; yours should be same as EA82 in diameter, but bolt holes are smaller than EA82.

OK, sounds good, thanks a lot

my ea81 with 4speed has an 8 7/8 inch flywheel stock alot of them came with the bigger one. but you have to look.

 

you need an adapter plate, and some new holes in your flywheel, to run that motor on that tranny.

yup, I'm pretty familiar with the whole procedure at this point, I'm going off of Subarino's post and pictures mainly as well as info from the handful of other folks who have done the same swap. I'm actually going to pick up the aluminum for the adapter plate and a couple of packs of jigsaw blades this afternoon.
