Scott is right on with the pricing and explanation about replacing everything. Although a used 6speed may be had for 5500 sometimes, you will need everything else that goes with it to get it fitted into the wrx. I have a Version 6 RA gearset(not special edition) that is cryo treated. I had it installed in my car for 2400$(new clutch not included in that price), but this was a special deal back a few years ago when i swapped cores with the GB motorsports. So they installed a fully built RA set into my car but i had to give them my tranny so they could build the next one. But the RA set will swap directly into the wrx with no issues with the diff, clutch, axles etc. If you are looking for an upgrade then i would suggest this, it is rated to handle 350 wheel TQ. I have a 2.5 block/GT30 with 340whp/300wtq and it will handle this just fine. The only problem with the RA sets these days is that it involves the shop(gruppe-s for example) to uninstall your tranny, have a transmission specialist install the new gears into your case and then reinstall your tranny and new gears back into your car. This leads to quite a bit of down time for your car and since we dont live 10 mins away its pretty hard. Im sure you could get a quote but i would assume that RA gears installed these days would cost close to 3000$. But in terms of an upgrade the RA gears are great. I would rate them as the best mod ive done to my car by far....the stoptechs being a distant second(yes i rate the tranny higher than the motor and turbo!). The better drivability and better gearing was well worth it for me. Tyson will vouch for the difference between the two trannys. If you are looking to 'feel' the difference, hit me up and you can drive my car to experience the difference. I guess in the end it will ultimately come down to how much you are willing to spend. the RA set is relatively strong, but not 6speed strong, but then again it costs quite a bit less. also it depends on how much power you are planning on having.
my 4 cents this time.
