Default 02 wrx motor swap to 00 rs

I already know some one who has don it just recently. WRX motor into a 99 RS. He only did the motor. Changed the flywheel and clutch rewired it and will be having it tuned soon.
All the research ive done says this wont work. ive ridden in it, its fun . So what is the part that wont work. Ive read on this forum that the earlier trannies are just as strong as the newer ones, just different gear ratio. Can someone shed some light on this. I now have a 00 RS and a spare turbo motor just laying around and im really tempted to do the same swap. But I do want it to be reliable and fun.

Any help would be appreciated
thanks

The RS transmission will hold the power of a stock WRX engine. Quite frankly I prefer the 4.11 of the RS over the 3.9 (or 3.7 of the later ones) in the WRX. The ultimate as far as I'm concerned is the 4.44 out of the Forester XT. What tends to kill the transmissions is the driver. In my experience I think that the final drive in the RS and Forester XT actually help take a little stress off the gearbox, either that or us old school guys actually know how to drive an AWD car

That said, you can always build the RS transmission up just like you would a WRX transmission. Same 5spd gear sets will drop right in. You can go from mild (stock 04 + WRX / or Legacy GT gears) to wild (full PPG dog box) You are only limited by your budget.
