ShadyNluvNit@charter.net Posted May 13, 2006 Share Posted May 13, 2006 What is out there for a transmission upgrade? Is it possible for a WRX tranny to bolt up and be an upgrade? Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted May 13, 2006 Share Posted May 13, 2006 manual or automatic? Quote Link to comment Share on other sites More sharing options...
ShadyNluvNit@charter.net Posted May 13, 2006 Author Share Posted May 13, 2006 Sorry, manual. Quote Link to comment Share on other sites More sharing options...
Dr. RX Posted May 13, 2006 Share Posted May 13, 2006 I'm not sure, but I heard that some of the hole in the USDM WRX trannies are threaded, to bolt to an older Impreza, those holes need to be drilled out. Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted May 13, 2006 Share Posted May 13, 2006 The final drive ratio will be different, but other then that....it should be relatively swappable. Quote Link to comment Share on other sites More sharing options...
ShadyNluvNit@charter.net Posted May 13, 2006 Author Share Posted May 13, 2006 Does that mean I would need to also swap out rear-end gears? Quote Link to comment Share on other sites More sharing options...

970subaru Posted May 14, 2006 Share Posted May 14, 2006 a wrx trans would not be much of an upgrade. for strength, your option is basically a set of PPG gears which is retarded expensive. dog boxes are cool as hell but expensive as hell. or you could go to a 4eat which is stronger but saps power. for better ratios, a 4.44 forester trans or an RA gearset will be better. your top end will suffer though.

ShadyNluvNit@charter.net Posted May 14, 2006 Author Share Posted May 14, 2006 Thanks. So I might as well just get another 2.5rs tranny rather than trying to upgrade with anything special. I just blew out 2nd gear in mine and I figured with the turbo kit on it, another stocker has a good chance of doing the same thing. Quote Link to comment Share on other sites More sharing options...
970subaru Posted May 14, 2006 Share Posted May 14, 2006 2nd is part of the mainshaft so you will need a whole new gearset most likely. maybe have a stock gearset cryogenically treated, should be like 50 bucks. take it easy on the clutch dumps and crashing 2nd gear also.
