Just an idea at the moment and wouldn't be implemented till after the end of the race season but does anyone know of company that would cut me a custom set of ratios for the T5 Gearbox?
The current selection of ratios available aren't really what i'm after and i'd like to fine tune a set to engine output.
I know one off manufacturing isn't cheap, but this would make a real difference to the way car performs on a Hillclimb.

Wouldn't Quaife help you out?

 

DJM Motorsport should be able to sort you out

 

DJM above would be best local option

GForce in the states already offer some ratios

Samsonas do some "universal" rwd dog and sequential gearboxes with a variety of ratios

Universal seems to mean a BMW fitment with an adaptor.

I think SQS used to do some T5 stuff, but havent seen anything listed for some time

A diff swap not get you near where you need to be ? Certainly be a lot easier and cheaper ?
Or try and hunt down a Tractive gearbox ?

 

I am thinking about fitting the 4.3 CWP but there will always have a long 1st.
Got to stay a T5 casing (due to regs) can do what ever I want to the internals (can't put sequential in thou)
I'll give DJM a look thou

Long first is great !

Or are the hills really tight ?

But a long first typically means the actual gearset will be much closer spaced so better for racing with a narrower power band. Likewise fitting a shorter diff will have a similar effect. Just be careful you dont go too short and end up spending all day changing gear. That's fine with a sequential, not so much with a synchro box unless it is pretty slick.

Gearboxman does some stuff too

From most searching Ive done over the years...usually the word "Elite" is followed by the word "problems"

 

Alan Young engineering can hob.
Great bloke to speak to, for one off pairs expect around £700 plus vat.

Don't bother ringing the Q word mfr.

The T5 ratios will be fine on your car mate with the 4.3.
