Default What tranny should I use?

When swapping my 2.5RS for a WRX motor, should I keep my Auto tranny in my RS or should I swap it with the 5 speed?

Thanks,
space

well, for preference, I would like to keep the auto for city driving...but I want to make sure that it can handle the HP incase I start modding the WRX engine...

Might I direct to doing some research in the Transmission forum. Only you are going to be able to make the decision.

Ok...well I was hoping to get some info off people who have done this conversion and kept the tranny they had....either if they liked it or didn't, if they encountered any problem doing the swap, and if they had to do it again type deals....

so if anyone would like to comment on this please do so....

Thanks,

FWIW, autos can usually take more torque and HP than manuals. OTOH, modding an auto (beyond a high-stall converter) is a bit more PITA. If I was drag racing and city driving, I'd go with the auto. For canyon carving or track use, the manual.

Yeap - Redwagon is correct. Reason ESX and Rigolis use Autos on their drag cars. I should use one in my project, but decided not to get so much power in my daily driver, and went the JDM 6MT instead.

if you change trannys, you'll have to change the rear diff as well... the RS and WRX have different gearing and you would end up breaking either the tranny or the diff before you even got the car outta the driveway.
