turbo on a 2.5rs, tranny questions

[subyrally]

i am planning on turboing my rs, i have the 4eat tranny in it. i am fairly sure that the tranny will not be a problem when i go turbo. i have one guy saying that i cant use a tranny from a n/a car in a turbo situation. another guy is telling me that there will be no problems what so ever with the 4eat. i know that it should be able to handle more power than the 5spd manual tranny that is in a wrx. the first guy i talked to is a mitsu guy and the second is as big of a suby fan as me:grin: . is there anyone that has turboed a automatic 2.5rs out there? did you have any tranny problems at all? i am under the impression that the transmission is the same auto that is used in the wrx, so i think that it should work properly.

I installed a turbo kit on a 98 RS and the tranny was already somewhat questionable from the owner "manually" shifting the tranny all the time. He continued to do this with the turbo kit, went through 2 engines by cranking the boost up and not having a clue as how to manage the fuel and insuffiecent injectors to boot. The tranny never did fail though. The 4EAT has an excellent track record with higher output engines. My 99RS turbo, just over 300Hp, is now at 147k with the 5spd MT (upgraded gears) but I expect that the stock one would have worked out, most 2nd gear frags come from not knowing how to drive.

what did you have done to your car to turbo it? there is an ongoing arguement at school, my friend says that i wont be able to turbo it with out putting in a new engine. my other friend says that i can run a turbo on the stock block. i know that ill nee to reduce the compression ratio, retard the timing, and get independant fuel management or a wrx ecu, in addition to all the parts, like exhaust manifold, up and down pipes, intercooler, fuel pump and injectors, and finally the turbo. what you think?
