l series to gen 1 legacy compatibility

[T'subaru]

I'm looking at a '90 legacy ej22 donor car for my '89 rx. Is there a way to also use legacy 5 lug hubs and disc's along with the rest of the ej goodies?Most info I have found is centered around the xt6's.

Thanks, Mark

if you have read the xt6 info you should have read about the lower control arms and tie rod ends.

 

i suppose the legacy tierod ends can interchange, otherwise the trick is to ream the hole on the knuckle since the shaft is larger on the ea82 tierod.

 

and same with the lower control arm, you have to ream the ball joint hole for the larger shaft on the legacy knuckle.

 

this is what i did on my 87 rx to fit xt6 hubs, and then swapped in a legacy hub and this fit.

 

this was a mock-up since it was never a complete project. i did not have the right axles.

 

for axles i would 1st generation impreza axles with a 29 spline count, if your car has the original trans.

 

you might be able to use the ej transmission if you customize the mount or salvege an xt6 mount, and that will eliminate the bellhousing issue if you go with the ej motor. But you will lose the dual range.

 

i have read about wrx gearset and vlsd to replace the lockable open center diff.

 

you might be able to fit later model brakes and calipers on the rear, but you are limited by using a real xt6 rear hub unless you modify or manufacture one to fit.

 

I believe there is a fabricator out of australia that makes 5lug swap kits

 

i am just passing general info from the forum

Thanks MilesFox,

I wanted to know if legacy suspension front and rear could be swapped into a L series, complimenting the ej's drive and power train. As far as the rx drive train I hav'nt decided which subi i will transfer to yet. I have a turbo wagon and just picked up an '86 gl sedan today, all ea82T powered. Disc brakes everywhere but no 5 stud.

The Legacy suspension system is completely different. Nothing will come even close to interchanging without major fab work to install the whole assembly under the car.

 

You should get into the EJ stuff. I know the EA82T's are cheap and cute and all - but mechanically they stink.

haha.. As of yet I havn't driven an ej powered subi so I don't know what I'm missing, but as the ea82t's die I'm going ej for sure. Thanks for the heads up with suspension issues.
