Had a good 2 sessions on the Mazda track and sprint this morning changed down to second coming into the wiggle at Blyton park and bang 2nd gear gone got towed back to pits could locate first and reverse to get it on the trailer home , forced the hand now to get a 6 speed in.

6 track days 430lb/ft = standered box will go !

CREWJ

Could have told you that before

Did anything else break too? At least the new 'box will be more robust.

Done well to last 6 track days mate.
Get the 6 speed in and you'll be fine.

I found the 6 speed a bit difficult to get used to after the 5 speed.

But you cant knock the abuse it can take !


I,m gunna try these uprated shifter bushes in mine i think ?

Lee you are broke PPG or standard 5speed?

We are running PPG(will be running too on 2.35L) and we are been several times on the track or drag strip and gearbox is great

Friend of mine has a 6 speed for sale for very reasonable money, Lee.

You will break it with the 2.35, its a case of when not if Jura

Fact.

It's done well then. I woulden't have thought 430 ft/lb would have have lasted that long TBH.

I assume then that a standard STi 6 speed gearbox isn't chocolate?

CREWJ

Nope, it's surprisingly strong.

Nothing is bulletproof,you can break 6 speed if you are not sympathetic to your gearbox.
I know will not hold the power for long,but really for us PPG is great just due ratios which are more suited for us on drag strip.

How long will last,who knows,but some people run at high 500bhp(in US guys run high 600whp)without the problem.If we have PAR straight cut,I would be worried more

If we will need to go with 6speed,we would go,as someone said " If it ain't broke, don't fix it "


Jura


Fact is only one,nothing is bulletproof,as my friend said Human stupidity is infinite

Is it not down to the 5 speed box design/construction more than the particular gearset that is an issue ?

How is the elite/clinic gearset doing now it has been around a while ?

Uprating the shifter bushes will help a lot. Just upgrade the front bush to a hard race one & also the rear one if you want.

Kartboy or Perrin are decent

I fitted a 6 speed to mine earlier this year, I went for a JDM 6 speed for the lower gearing & I love it. These seem to be going for more reasonable money now & are stronger & more cost effective than PPG. If you can afford it DCCD will give you more to play with on track too.

had plenty of rally cars with hi-torque on std 5spd boxes last no problem, and road cars that last less than 1 day.............

has a lot to do with how & when you shift (as well as a large dose of luck i guess) - in particular high rev down changing is an almost sure-fire way of destroying 2/3rd gears

Is this to do with grip/surface? E.g. On gravel I assume you don't get the same forces through the box as you'd break traction whereas on tarmac you can't break traction hence end up with higher forces acting on the gears?

I was blipping the throttle on change down but not really high revs just to bring the gear in gently, no warning was given just the bang il upload a vid of it when it's on you tube
