Hello to all, I have some questions regarding my Forester 98, it runs with the EJ25D with 100mm Mahle Forged Pistons and ACL Bearings mods. I was wondering if I could use a Turbo Stage 3 Clutch Kit from a 2000 WRX on my EJ25D to replace the old one. The one it has now is a salvaged one I got from an EJ22 from an 2000 RS that was totaled. It seems to be slipping at certain moments when I take off at stops, or when speeding up; sometimes I have to pedal-play on launch to avoid too much slippage. The reason I chose the turbo clutch kit is because the OEM can go localy for around $120 to $140, and I found Stage 3 kits at Ebay going for $159 to $189, so why not pay a little more to the get the good stuff and the grip that I want, also I will be stepping up the power later on, and I know OEM won't do, so why not get the turbo clutch kit now so its not needed later on. Thanks for the attention, love the page by the way, I finally found a decent page about subies that won't ask for money to answer your questions.

No, you can't. Turbo transmissions have a different spline count, and they have pull pressure plates not push pressure plates. You have to use an n/a clutch on an n/a transmission.

Thanks a lot Rally, that's the one question I had not been able get an answer for. So the trannys are different after all, thanks a bunch, now I know which one to buy.

Lots of clutch companies make higher grip clutch kits for the NA engines. Shouldn't be too hard to find a performance kit that will fit and work properly.

Normally I would suggest avoiding the higher stage clutch kits, since they tend to wear quickly and are not easy to drive with street use.

Yes, indeed true. I have made my research and the best option for the average street driving routine would be a stage 3 as it still used spring loaded plate with ceramic-copper composite pads, stage 4 and up have rigid plates and may be unforgiving on torque sensitive OEM parts such as engine bearings, drive axles, and u joints.
