hmm.. i'm not sure about the L gearing.. but the wrx is pretty tall. If you can find a rs tranny.. that would suit much better. IMO

That's what I've heard/read. The rs gears aren't any weaker than the WRX so might as well go with something a little more useable.

you are going to need a new clutch either way. i wouldnt run a stock L clutch with a wrx motor. so its just a matter of which clutch you end up buying (upgraded L clutch or wrx clutch). and as far as flywheel, wouldnt it be a good time for a lightweight flywheel anyway ;-) i dont know about the gearing on the L but if its anything like the RS i would stick with it. im planning on keeping my rs tranny with my wrx swap. the wrx tranny has tall gears, so unless your goal is top speed runs, the rs tranny will keep you faster in the turns.

the final on the RS is 4.111 (on the 02-03 at least.) im assuming you mean you have an UPGRADE NA exedy clutch, because i dont think the stock replacement will like the wrx motor. i say use the L tranny for now (unless the L tranny is prone to breaking) and then later you can do the jdm or whatever if you feel you need a different ratio.

I used Legacy GT Gears and diffs (Front and Rear) in a WRX case. I wanted the gearing of the legacy with the strength of the pull style clutch. Gears, Front and Rear diff were from a late 1998 Legacy GT, WRX Case was from a 2002, and the transfer case and center diff were from a 1991 Turbo Legacy.

im not positive on this, but cant you just change the clutch release mechanism from push to pull? i was under the impression that the tranny housing between the wrx and rs were the same, so i figured you could just switch over the release mechanism.. anyone have a answer on this?

I wouldn't trust the L trans with power.... IMO I don't know though just me? i have a 94 L with EJ20G swap and with the jdm drivetrain... I really like it and over all feels better than the L but your car is newier soo I donno? if you go RS or wrx you'll have to change over to hydrolic or figuar out a way to keep it cable i konw its possible.

The bell housings are different. When I get into the shop today, I'll take some pictures. Instead of having a ball that the clutch fork pivots on (the push style transmissions pivot on a ball) the pull style transmissions pivot on a pin (about 3/4 to 1" in diameter and about 6 inches long) that runs through the fork... The fork design is completely different also. It's not just a matter of swapping forks.

ill throw in
your tranny will be fine
i have 175k miles on my L tranny (w/ ej20G)
the usdm wrx transmission is not well matched to the ej20 .. at all it too high
pulling the engine reallly isn't that tough after the first time

i say go with the tranny/starter/flywheel/clutch/cable you have deal with the wiring of the swap then if needed do the tranny later
