02 wrx 5 spd to 1992 legacy 5 speed conversion questions

[jerelm]

Hi there everyone.. I have a few questions.. I have a 91 legacy Turbo originally a automatic Trans.. I swapped a 02 wrx 5 speed into it and the Trans blew up on me.. So while I'm rebuilding it I purchased a 5speed 1992 legacy non turbo Trans.. I was wondering what all i needed to change to make it work.. I have Trans, drive shaft, rear diff, starter and flywheel from the 1992 non turbo.. Will i need to change the axles, drive shaft, and clutch to make it work?

Hi, welcome to the forum! I know you'll need
-a pedal set from a cable clutch car,
- clutch cable
- clutch kit that matches your new tranny

I'm sure others will chime in about anything I missed

Welcome to the BBS.

The main issue is that the non-turbo transmissions have a different style clutch setup. The non-turbo uses a "push" style clutch disengagement, while the turbo uses a "pull" style. To use the non-turbo setup, you would have to use a hydraulic push style clutch slave cylinder & clutch fork. I am not positive, but I think the pivot ball point for the cable vs. hydraulic clutch fork is different....but I can't confirm that. Also, you will need to use the non-turbo flywheel, clutch, & pressure plate.

The driveshaft and axles will be the same, however you will need to swap out the rear diff to match the trans.

If you could get a hold of a push style clutch setup, that would really be helpful so you don't have to mess with converting the clutch fork assembly.

Alright thanks so much guys.. I have the rear diff so I will just go to the local junkyard for the push style clutch assembly.. Should be a cheap fix until i finish the Wrx trans rebuild.. Thanks again for the info..

[jerelm]

Will the wrx shift linkage work or do i need to get that from the junkyard too?

[mike-tracy]

You can reuse the WRX shift linkage.

[Legacy777]

You just need to swap the shifter joint on the 92 trans to the newer style. Easy job though.

I started taking the clutch and break pedal assembly out and noticed a plug on top each one of them.. Are they some sort of sensor? I didn't do the Wrx 5 speed swap so I'm sort of confused.. Will i need to swap the sensors or plugs whatever they are..

[mike-tracy]

Yeah you'll need those sensors for the incoming pedal assembly, unless it has those sensors already.

So i noticed there is 2 cables off the 92 n/a Trans from the shift fork.. One us the cable to the clutch pedal and the other one goes into the brake cylinder.. i noticed my cars current wrx set up is completely different.. It looks very confusing to me..will i need to replace my brake cylinder to make that work? My car is a 1991 legacy ss.. Also does my car having abs make this a problem as well?

That's the hill holder, don't worry about it. Should be fine without it

[jerelm]

Thank god easy fix..thanks..didn't know if it was a return spring or something

[Legacy777]

Yeah, you can just remove the hill holder cable assembly. It'll be fine without it.
