Transmission swap

[Mason_Anthony14]

So I have a 93 impreza transmission out of the car and I have a 2002 wrx wagon that needs a new tranny, will the 93 tranny work in the wrx?

Yes but No. You need a matching rear differential for the '93's 3.90 front diff.. The transmission will work with an N/A clutch and slave but is not ideal.

N/A clutch may not be robust enough to handle the torque of WRX motor. Clutch may not last long.

call around, you might actually save a little having your trans rebuilt. Or a speed shop may have a 5spd leftover from a 6spd swap.

 

I'd expect being in CO, both shops capable of trans rebuilding AND used transmissions should be easy to find.

 

my 06 trans ate 2nd gear - rebuilt by a shop in DFW for $2k . You might do better - if you can R&R yourself - maybe get it done under $1500.

It won't, but it would let the weaker trans last longer. Clutch/ trans would only suffer if it was hammered

 

Plenty of Impreza turbo swaps use " RS " transmissions and hold up with weaker clutches, like they are special, but we all know they are Outback/ Forester/ RS/ GT 4.11 transmissions. I guess the lower gear probably helps keep a load off of the transmission gears by applying the torque to the street faster.

 

 

My advice would be to go with another turbo 5spd. You can use any turbo 5spd you want ( USDM or JDM ) that you can find as long as you match the rear axle ratio.

I'm headed out..but Push vs. Pull (FW/PP/Disk must match), and speedo install may be issues...but manageable.
