Question Cobb Stage 2 + Many Miles Owners - Speak Up

Hi,

So my AP and Cobb Catted DP arrive next week They'll go with a gutted UP and stock CBE on an otherwise stock 02 WRX.
I've done all of the research but still have on nagging question. I know the WRX tranny is the weak link...

Has anybody run a similar set up for a long time (30,000 miles or more?) on a daily driver? I drive it hard, but I'm always nice to the driveline - no hard launches, clutch drops, always rev-match.

I hope this setup (I plan to quit there, power-wise) will be perfectly reliable for a long time. Has anybody had problems at this power level with the tranny? I need to hear from people who don't 'race' their cars, but plan to own them for a long time without always replacing parts.

I plan to upgrade stock tranny parts when their lifespan ends...hopefully not too much sooner because of the extra power.

So, has Stage 2 killed anyone's tranny (that drives somewhat sanely?)

I'm over 20K at stage 2+. Most of that stage 2.5. I don't race, and I'm smooth on the tranny. I don't worry about it, although the 04 trannies are supposedly improved. I expect to have this car a long time. I don't expect that at these power levels and the conservative Cobb tune, you won't hear too many horror stories.

this transmission rumor has gotten WAY out of control. with that said, i've had my stage 2 setup for almost 20k miles with no problems. not 20k worth of commuter miles either. track days, rallyX, LA stop and go traffic.
also, the stage 2 setup isn't really enough power to add that much more stress to the drivetrain. get a dyno and see what i'm talking about.

Great news so far! That's what I expected out of my rock-solid Subie. I suppose it would take a bit longer to see early failure of driveshafts and gears, but maybe people are burning through clutches or something...

Looks promising though. Can hardly wait!!

I agree...but will add that it is the weakest link, you just have to up the power more than we are talking about here to break it. Just don't clutch drop.

The rumor (and reality) really got going with a vf22 and above. The stocker and the vf30/34 under AP deliver the power smoothly. There really is no hit or jerk to the drivetrain in these maps.

I've had no clutch problems either, and that's with this being the first MT I drove in 15 years. It was ugly for a while

I've had stg.2/93 for 10k miles and I had to replace my clutch due to bad driving habits.. I only autoxed it once. Its all about your driving habits, if you abuse it, you are asking for it. I've had the new ACT HD street clutch for 500 miles and I've been babying my ride...Anyways, I have 40k miles..

My driving habit:
-love to downshift around turns
-I rev match to a stop
-hardly use 4th-5th gear due to the roads around the area avg. 35 mph..

Just drive like a grandma and you'll be fine..

I've autocrossed and taken my car to the drag strip, gone from stock to stage 1 to now stage 2, and I'm at 44,xxx miles with no problems to the transmission (knock on wood). Clutch is feeling a little worn, but considering what I've put the car through, I'd expect that.

The transmission is comparitively weak, yes, but it's not THAT weak. It's all about the driver. Seriously.

Stage II won't kill your tranny, only bad driving does that.

I have 35K miles on stage 2 with no problems either. It's such a good car I plan on keeping it for a long time. Engine and tranny work like butter, no issues at all.

Mine got better.

21 in the city, 28 on the highway.

My last trip from Austin to Dallas (TX), I drafted behind a few 18-wheelers and got about 30mpg.

I have had my stage 2 for about 20K driving pretty "grandma-ish" during the workweek commute, and letting loose on the weekends and have had no problems with clutch.
