Hydraulic to Cable Clutch Conversion

[Wangan Wagon]

Hey guys. I was wondering what I would need to do in order to swap my cable clutch pedal system into a hydraulic-based transmission? The reason I am doing this is my gearbox is almost completely shot and I prefer cable over hyraulic clutch pedal systems. Oh, I have a 96 leggy wagon cable clutch tranny and I am swapping in a 98 leggy wagon hydraulic clutch pedal tranny. Any help would be greatly appreciated.
P.S. - this is only one of many things coming from a parts car.

need to swap the cable fork in place of the hydraulic style one. and swap the cable bracket to the other trans.

You realize that if it has a hydraulic clutch, its probably from a 2.5 and has a 4.11 (or higher) and not the 3.9 that you should have with your 2.2, right?

Just checking.

Alright, so that's all I need to do huh? Perfect....

To ouch1011, the parts car I am getting is a 98 Brighton, so I think it's still the 3.90 FD.

The 90-94 non turbos had 4.11 FD, but I think you'd have to reuse their axles. (the Turbos from that era have axle stubs on the diffs). Easiest would be to switch to 3.9FD then.

Forgive me if I am talking out of my ass but....

1) IIRC arn't the brightons cable assist even in the 97+ chassis?
2) There shouldn't be any reason why you cant just swap in the proper FD transmision. Worst case swap the tranny + diff and your set.
3) The slave should be swapped from the old trans the new trans.
4) The hydraulic system just controls how/when and what pushes the fork so your cable system should be left untouched.

If you wish to have a bit more bite from your tranny go with 4.11 or 4.44. 3.90 is slow for city driving but good for long runs.

Also, with the cable-trannies, I would imagine there are very limited options for clutches that can hold much power over stock N/A levels, right?

Subaru was weird with final drives. It depended on the year, but some 2.2's were 3.9, some were 4.11. The 1997-1999 LGT had a 4.11 and the 1998 2.5RS had a 4.11 (EJ25D). LGT's from 2000-2004 had 4.11, and some L's (2000 was a notable year) had 3.9.

You would be best to actually look up what final drive you have in both cars before doing any swapping, because chunking a center diff isn't going to be a fun experience.

you can use any NA 2.5 Hydro clutch you want with a 2.2 and Cable tranny, so its not really any worse than any other NA Subaru.

How does a cable slave system effect the clamping power of a clutch disc?

I am just saying 2.2 / 2.5 clutches are interchangeable so are performance clutches.

From what NASIOC is preaching 5MT is a universal goodie bag

From personal experience my buddies BK is running an EJ25D w/ EJ25D clutch + brighton tranny w/ cable clutch setup. Plug and play. This combo works well for highway mileage.

This guy is/was talking about building a 600whp monster. Might be a bit rough on a cable clutch n/a tranny.

My 98L, 2.2L had a cable clutch...

Problem solved :-D it should be plug and play

Maybe I misread, but he is wanting to replace his HYDRAULIC clutch system with a CABLE. IIRC the 2.2 never came with hydraulic except for turbo models, and they usually (almost always) have a 3.9FD. If he has a hydraulic system now, he most likely has a 2.5, which pretty much never has the 3.9FD.

Thats what I was saying. If he has a 4.11FD now with his 2.5, then the 3.9FD that will likely come with the cable clutch tranny won't work.

What we were saying is he needs a cable-clutch specific fork, then he can use whatever n/a tranny he wants. Chuck even mentioned that both 2.2 & 2.5 clutch kits fit.

Well I guess I have to take a closer look, but the clutch pedal feels like a hydraulic, and under the hood the tranny looks different around the area where my 96's cable clutch system is. The 98 being a Brighton has to be 3.9 though like my 96 L. I guess I'll find out more specifics when I start to take the cars apart, but that might not be for a while with my newly acquired spinal injury. I mean a WHILE.

^ it could have a hill holder on it, that would make it look different. but anyway, just look at the firewall, if there isn't a clutch master cylinder, its not hydraulic.

[chuckthefuk]

^^
Could be. I posted a thread about the Hill Holder malfunctioning and posted some pics. It may be helpful to determin if you have one or not.

Does the hillholder have something like the throttle cable wheel-thingy attached to it? If so, I think they may both just be cable. If not.....poo.

[StatGSR]

Like we said if it has a 2.2 it should have a cable transmission (Brightons have a 2.2). to my knowledge, no non-turbo 2.2 came with a hydro tranny....
