EJ Engine and Transmission into a RX

[[HTi]Johnson]

Goal: Put EJ engine and tranny in RX.

 

Can anyone predict what I would need to modify that's different from just the engine swap?

 

Like driveline and axles?

[baccaruda]

Yep.

 

Depending on the tranny, you may also need to add a slave cylinder if it has a hydraulic clutch.

also also the rear differential gear ratio.

[Numbchux]

the RX axles will work fine with the EJ trans.

 

linkage needs to be modified.

 

tranny mounts are different. either custom crossmember, or XT6 front and rear crossmembers with EJ center section.

 

driveshaft needs to be adjusted 55mm (pretty sure it needs to be longer....but I could be wrong).

 

rear diff......depends what trans you're using. if it's a 3.90 trans, just get a 3.90 EA rear diff. otherwise you'll need to use the EJ rear diff. physically mounting it is easy, as all r160 mounts are the same. but you'll run into some axle challenges, as there are a few different kinds of axles. first gen legacies (maybe others) use 23-spline stubs that are compatible with EA DOJ cups. otherwise, you maybe be looking at hybrid axles.....possibly custom races.

I say you weld the center diff, run only rear axles in a stock EA82 Diff, and have a 2.2 liter RWD RX

Holy hell!! That RX would be a madman!! But AWD is so much fun....
