Default is this to much on my tranny?

i have a 03 wrx, samco hoses, perrin pulley kit, and up pipe, im putting in a down pipe and exhaust, how much approx. hp will all this give me and someone told me this might be too much for my stock tranny to hold and i should eventually get a sti tranny, is this true?
thanks
taylor

That all depends on how good of a shifter you are and how big of a shockload you place on your drive train, I think you should be just fine as long as your not slamming gears.

The tranny will last so long as you don't beat the hell out of it. Launches and slamming gears will make that tranny go bye bye fast. Take care of it.

Getting on the gas a bit as long as you are RPM matching and shifting smoothly will help tremendously!

Make the most out of your mods and get EM too. That will put you in the area of 230whp.

The tranny will be fine. There are many out there with a ton more power than you on the stock tranny. Just know that 6k drops FTL

Realistically, about 15 hp increase over what you already have.

With a decent driver, your tranny/mod combo will be fine. You don't even have EM. If you have the old '03 tranny, I think a full stage 2 is about all I'd do. If you have the later revision, you could prolly go stage 2.5 On that note, if you are worried about the longevity of your car, get some EM before you do those mods. The EM in combo with the TBE will prolly give you about a 30-40 hp increase over what you already have...but it really depends on the gas/tune.

Another thing, if you are not looking to go much past stage 2/2.5, an 04 or newer WRX tranny will be plenty, and should bolt right up. In fact, a good friend of mine is running a VF22/Exhaust/FMIC/Ecutek (basically OTS map) on the '04 tranny. It is about the limits of it, but it does not sound like you need more than that.

The STi tranny is for going really big, hence the hefty pricetag.

Comming from someone who broke 2 WRX gearboxes... I totally agree.
I broke one at or near stock power also.

Drive it easy and it will last forever.

A WRX with a TBE puts down 20-30 more whp. Or about 180-200 depending on the dyno.
