06 STi so is a bit stronger. But never had an issue with the MY98. Had it from 38000 to 83000km and drove it very enthusiastically but never abused it. Didn't used to launch the 98 though. Save the piggy for AHG or drags. Nice to it on the street.

Think the big thing is if you do it all the time your going to break stuff. Occasionally yes there is a chance things will break and you will wear things quicker but if your nice to it 99% of the time you should be fine.

Choose carefully if you do flog it on the street. Coarse bitumen gives heaps of grip and is very hard on the drive line. Motorplex is pretty slippery ( especially if you go through the puddle ) is much easier on things.

Just treat it with respect like any other car lol yeah sti 6 speed is slightly stronger than the 5 speed but they all break if pushed hard enough like any gearbox!!

If ya want a strong box/casing p1's had a honey comb type lining in em

Great for building a nice strong box.....

I broke 5 boxes in my old car.

I NEVER broke them from copious limiter launches. They always died from ramming them threw 2-3 change.

Just be ever so slightly gentle and humane to the thing and they will live.

Once I worked that out my last box last for ages with 250 atw.

5 speed boxes are unbreakable. I tried to break mine so many times and failed.

Yours was a newer 5 speed not the classic 5 speed which does seem to be a little less tough.

Not saying your doing anything wrong. Im saying that with a bit of a ride off the line there isnt going to be to much difference. Besides if your chasing quarter mile times, why bother trying to thrash a stock wrx down the quarter?

As for the 6 speed, they are almost bullet proof. You cant even begin to compare the 5 with the 6. I never broke my box slipping it off the line, the only time it broke was once it was in gear and I dropped the hammer down then bam....stripped it clean. As teejay said be kind and they should be good for 250kw.

7000rpm side step of the clutch = ET 13.58

5500rpm riding the clutch off the line = ET 13.39, the .4 reaction is shit (unlike Mr Crash's commentary) because I was trying to nail it as the revs were rising.
