lmdew Posted May 31, 2010 Share Posted May 31, 2010 Is the 90-94 Legacy 2.2 a alternate for the trans in a 1.8 Impreza? I know the motors will bolt up, but I didn't know about the flywheel and trans input shaft. Thanks, Larry Quote Link to comment Share on other sites More sharing options...

Thanks, Larry yes, auto trans anyway, pretty sure the 5 speed is the same. subaru isn't large enough to have a different trans for the limpreza. would this be a FWD 5 speed? then no rear diff to match.

lmdew Posted May 31, 2010 Author Share Posted May 31, 2010 Yes, I just wasn't sure on the Flywheel as I know they use different size clutch disk. Quote Link to comment Share on other sites More sharing options...
johnceggleston Posted May 31, 2010 Share Posted May 31, 2010 Yes, I just wasn't sure on the Flywheel as I know they use different size clutch disk. it looks like you're right, different flywheel. it isn't shown as being used on the legacy. http://opposedforces.com/parts/impreza/us_g10/type_2/engine/flywheel/illustration_1/ although this link shows the impreza ej18 AWD shared a flywheel with the ej22, so i don't know.

Twitch de la Brat Posted June 1, 2010 Share Posted June 1, 2010 Now are you replacing the engine or the transmission? If you're replacing the transmission, then you'll need new axles, as the FWD 93 Impreza axles are 23 spline rather than 25 like the majority of the EJ. As for the engine, I believe you can use everything that's already on your current engine and be just fine. Twitch Quote Link to comment Share on other sites More sharing options...
lmdew Posted June 1, 2010 Author Share Posted June 1, 2010 The Trans. Are the axles 23 spline on both sides or just the trans stub shafts? Quote Link to comment Share on other sites More sharing options...
Twitch de la Brat Posted June 1, 2010 Share Posted June 1, 2010 Both the stubs and the axles are 23 spline. When you switch to another transmission other than a 93 FWD Impreza, you will need to get AWD transmission axles or auto axles. The wheel hubs are just the EJ setup, so that won't change.
