REbuilt strong 5 speed UK Box
Does anyone rebuild standard UK classic boxes. Stonger to take circa 400bhp ?
Paul @ Zen ?. or Anyone ?. How much are we talking. ?.
I have thought about a 6 speeder, but like a 5 speed box as a road car, and thought it worth exporing a built 5 speed box first.
Thx
Rob

if its going to cost around 2K for a 6 speeder 2.5K for a built PPG is not so silly. But 3.5K is just mental unless for pro use.
Gearbox , options, diffs, etc is a mindfield once you start to look at it.

6 Speeders can be had for less than that. Also factor that you need a donor box for the built 5 speed whereas you dont with the 6 speed.
The difference is more like £1k between the two options - both very capable, but with different ratios.
I really wanted a 5 speed on mine so I didnt mind the £1k odd difference.

Getting a good 6 speed, and getting it fitted may well cost more than £2k. Becoming more available to a certain extent, but many cropping up with slight problems.
Forrester 6 speeds and the some of the latest 06 versions have the longer ratios which should make a much nicer box for larger engines.

This is a nightmare.! I feel like bolting up another UK 5 speed again and giving another one a second chance.
Fortunately I brought a UK 5 speeder as a spare a while ago just in case my one blew

Running all that power doesnt come cheap.

Hi Nielo - One thing can be said when I stripped 3rd gear today on my box, I consoled myself with the fact the car is definately pulling like a steam train and the torque is immense. It was asking alot when I floored it in 3rd at about 30mph.
This damn car is costing me a fortune and don't seem to be stopping.
Anyway's just brought myself a built type R box as above. So should be good for the power/torque just hope I can live with a lower top speed. As a comparison it looks like difference is about 500rpm. My car holds 3K at 80mph. The type r box is at about 3500rpm at 80mph. So shouldn't be too bad and can only add to the perception of speed at lower speeds.
Should be a rocket from 0-100mph.

Fortunately when my box blew today I was 500 yards from home, and still had 1st,2nd 4th and 5th.
I suppose with all that torque i could just forget about 3rd. Who needs 5 gears anyway

Rob;
What EXACTLY do you mean by 'built Type R box'?
Yesterday, Gerry's 2,5 was on a Type R box, and the ratio's were great, and seems to cope with the torque of the 2.5 well.
Anything special in the box you have?
Graham.

The box as standard has a steel fork for 3rd to 4th, and the gears are beefier than the UK versions.
My ideal box would have been a UK 5 speed built with the slightly longer gears (but couldn't justify the expense), but out of a choice of a 6 speed or this I am hopefully going to be pleased with it, and its cost me less than going the 6 speed route.
Very pleased to here the ratio's were great on a 2.5 .. as this was my only concern.

Rob,
You sound very 'box' knowledgable alll of a sudden, seem to recall reading these words last night in an email
Quote :
Its essentially a subaru type R box from a 1999 V5 car. Fitted with a front 3.9 crownwheel and pinion from a MY01 UK box, from the same UK box it has the transfer box and 1.1:1 Drop gears.

Anyone looking for a broken UK box with knackered 3rd gear for a project or a built box ?.
What you got eyes on my box for ? - Its no different to yours ? is it ?

No diferent no... but my box has already had new bearings put in it at 27,000miles and 270BHP.
Due to the 2 tapper bearings (one big, one small) somewhwere in the rear of the box failing. Nnot sure what they were attached too though.
Now running 320BHP and 300+lb/ft, so not convinced it's up to it.

Also it would appear the type R have group N gears and slightly thicker than STI gears, and also this box has steel forks, which I don't think the STI's had.
I stand to be corrected on all this, but its a case of suck it and see. But its got to be better and stronger than my busted chocolate UK box.
Its being bolted up Tuesday next week with some nice new castrol syntex so will report back what I think of it and its gearing.
