    I'm sure its possible ... but the cost would probably make you think about selling the car entirely and just getting an STi.

    Assuming it would all bolt up like it does in a WRX, you'd be looking at a complete 6mt swap from an STi, including driveshafts, hubs, diff, and transmission.

    Even that list isn't complete, as you need an ECU or stand-alone DCCD controller to actually enable diff control. Without a controller, the 6-speed would be locked at a 50-50 torque split, which is fine, but sort of defeats the purpose of the swap, other than getting the STI box.

    Here's one example of a stand-alone controller which offerr the OEM DCCD functionality, plus a lot more: DCCDPro Universal Controller [DCCD_Uni] - $395.00 : DCCDPro, Active Center Diff Control!

    That's pretty cool actually. I'm assuming it only works with a system designed to have a driver controlled center diff though?

    Verry true a sti would be about the same price in the long run. I just cant bring myself to buy a sti with 90,000 miles, with the turbo life span that it has, and the timing belt. Clutch if it was owed by a younger guy. And a "sti sport" 5dr would be a more everyday car.

    Meh. If you're gonna spend 20k+ on a used car, you can spring for a timing belt. As far as mileage goes... my WRX is going strong at 171k, modded and raced monthly. Spend your money how you want, but I wouldn't worry about picking up a well cared for STi with 90k on it.
