natext6 Posted August 8, 2012 Share Posted August 8, 2012 I found a really good deal on an 04 wrx clutch. Unfortunately, the car it is intended for (xt6) has a cable actuated clutch (if I'm saying that correctly) . So the question. can such a conversion be done(cable-->hydraulic)? And is it worth it? What would I need to go through with this? Quote Link to comment Share on other sites More sharing options...
WoodsWagon Posted August 9, 2012 Share Posted August 9, 2012 The WRX clutch is a pull type pressure plate, the throwout bearing clips into the fingers of the pressure plate and pulls on them to release the clutch. The xt6 is a push type pressure plate, the throwout bearing rests against the fingers and pushes into them to release the clutch. It's not an issue of cable vs hydro, it the completely different release design. The only parts of the clutch you could use are the pilot bearing and the clutch disk. You can swap to a turbo pull type transmission if you want, but that negates the savings of getting a good deal on the clutch. Quote Link to comment Share on other sites More sharing options...
natext6 Posted August 9, 2012 Author Share Posted August 9, 2012 I'm replacing the transmission as well....and the engine(ez30:headbang:) Don't suppose you could point me in the right direction in terms of which transmissions will work and which wont?

In that case you need a turbo pull-type. Any of the 5MT pull-type transmissions will work. EJ205 cars, EJ22T cars, and many JDM variants.

idosubaru Posted August 9, 2012 Share Posted August 9, 2012 so there's no way to use the WRX clutch with a cable set up? what benefit does the hydraulic clutch have over cable. the slave cylinder and hose failures have deterred me from wanting one.

GeneralDisorder Posted August 9, 2012 Share Posted August 9, 2012 so there's no way to use the WRX clutch with a cable set up? Not with any parts that Subaru has ever made. what benefit does the hydraulic clutch have over cable. the slave cylinder and hose failures have deterred me from wanting one. The clutch can be stronger and the fork lower profile.... and with the pull type a cable would be a mess to implement. The failures you talk about are not seen on the turbo version.

natext6 Posted August 9, 2012 Author Share Posted August 9, 2012 How sturdy are the EJ22T transmissions? Could an EJ22T transmission handle the 49 extra HP of the EZ30? ('03) Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted August 9, 2012 Share Posted August 9, 2012 (edited) Easily. There is essentially no difference between any of the turbo 5mt transmissions from 89 to '04 or so. The 22T transmission has the same components as a JDM 276 HP EJ20 tranny of the same era and the turbo engines make a lot more torque than the EZ30 and there's tons of people making a lot more than an extra 49 HP on the 22T. It's not hard to get to 275 - many folks are at or over 300. Remember - the EZ30 is a station wagon engine...... You can't do stupid things like 4 wheel burn outs because they weren't designed for that. Otherwise they are quite strong. The early WRX transmissions got a bad rep because of how silly Americans drove them. Too much grip - you are supposed to use that to go, not to chew up tires.

natext6 Posted August 9, 2012 Author Share Posted August 9, 2012 Great info! Will I have to change my pedal box? Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted August 9, 2012 Share Posted August 9, 2012 Great info! Will I have to change my pedal box? Of course - turbo clutch requires a hydro pedal assembly. GD Quote Link to comment Share on other sites More sharing options...
natext6 Posted August 10, 2012 Author Share Posted August 10, 2012 (edited) And so! Which cars can I steal that out of? Please forgive the stream of questions, I'm still getting a knowledge base going Edited August 10, 2012 by natext6 Quote Link to comment Share on other sites More sharing options...
WoodsWagon Posted August 10, 2012 Share Posted August 10, 2012 mid to late 90's legacy outbacks with a manual trans are the cheapest source, but you'll need to modify it and your pedal box to meld the two together. Quote Link to comment Share on other sites More sharing options...
natext6 Posted August 10, 2012 Author Share Posted August 10, 2012 (edited) Unfortunately I don't think I could Photoshop two pedal boxes in, and have it look good! Any other cars I could check? Edited August 10, 2012 by natext6 Quote Link to comment Share on other sites More sharing options...
T'subaru Posted August 11, 2012 Share Posted August 11, 2012 http://www.ultimatesubaru.org/forum/showthread.php?t=112285&page=5&highlight=T%27sunami Check this out, you need a pedal box out of a wrx ( should be easy to find ) and do the mods I did. The acc pedal is seperate on the wrx's, dont mess with it, just use your ea82 pedal. Quote Link to comment Share on other sites More sharing options...
natext6 Posted August 12, 2012 Author Share Posted August 12, 2012 The template you made, was that to change the vehicle from auto to manual? Quote Link to comment Share on other sites More sharing options...
T'subaru Posted August 12, 2012 Share Posted August 12, 2012 The template you made, was that to change the vehicle from auto to manual? No sir, The wrx pedal box as the ea82 pedal box mounts to the brake booster mounting studs inside the car ( exact same bolt pattern ) and the template as crude as it looks was layed out with the wrx pedal box and clutch master cyl mount bracket on the pedal box. I then from inside the car put the template on the brake booster mounting studs and pilot drilled the clutch master cyl holes from inside the car with an 1/8th inch drill bit, then finished drilling the holes for the clutch master cyl from under the hood. IIRC the hole for the clutch master cyl body was about 5/8 or 3/4 inch in diameter done with a step drill, or unibit...works out sweet! My wagon was an auto but it doesnt matter as far as using your ea82 acc pedal portion of your original pedal box, just cut it off as shown in the pics. I used a 4" angle grinder but a hacksaw would do the job just as well. I bought my wrx pedal box off of NASIOC from a guy parting an '07 wagon IIRC Quote Link to comment Share on other sites More sharing options...
natext6 Posted August 13, 2012 Author Share Posted August 13, 2012 Could I run a 1998-2001(ish) WRX transmission? would that work? Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted August 13, 2012 Share Posted August 13, 2012 First year for usdm WRX was '02 so 98 to 01 would have to be JDM..... That said - yes the wrx clutch will work with any EJ turbo tranny from '89 to '04 at least. GD Quote Link to comment Share on other sites More sharing options...
natext6 Posted August 13, 2012 Author Share Posted August 13, 2012 I did a bit of research, and it seems like subaru changed to all pull type transmissions after 98. Would an 00-04 legacy 2.5 trans work? Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted August 13, 2012 Share Posted August 13, 2012 Don't know where you got that info - it's the other way around and the year is completely off. Somewhere in the mid 2000's ('05 maybe for the EJ255?) Subaru switched from pull-type to push-type on the WRX, OB XT, Forester XT, etc. The 6 speed remains pull-type to this day. Thus you cannot use ANY non-turbo transmission with a pull-type clutch and you cannot use many of the later model turbo 5 speed's either.
