Is it possible to fit a longer 5th gear?
As above really, the IB5 box i'm going to be fitting has quite a short final drive (similair to an XR3i) and so will be high up in the revs at motorway speeds.
I was wondering if it's possible to fit a longer 5th gear retaining the final drive for 1st-4th acceleration? Or would this not work as there would be less teeth and so not engage properly?
Oh and if anyone knows where I can buy a BC/IB5 5th gear puller that would be very handy as I cant find one for shit!! lol
Cheers!

Yes it sure is mate, guy whos going to be building my box has messed around with several final drives to drives to bring the revs down on the motorway.Will find out what they are, iirc the last one he did was a 3.5 final drive which bought the revs down to around 2.5k at 80mph

Fairly sure it's possible, try a Ka 5th gear - that's really long. Mate of mine had a Ka turbo conversion he did himself, rebuilt his IB5 with ST150 gears 1 -4 and left the Ka's 5th gear in because it was so long, so he had loads of accelleration and a cruising gear.

The final drive is 4.25 which is great for acceleration 1st-4th but 5th needs to be longer for better economy on the motor way, or at least I would like it to be!
No probs, it took me fucking ages!

Not really helpful, but I've always found that a long final drive have given the best acceleration on a turbo car with good powerband.
As an extreme example. The best 0-100km/h times were achieved with using second gear only. When power is everywhere, shifting just loses time.
I've had all the ratios, started from 3.84 then to 4.27 and now happiest at 3.54.

It says in that thread that the diesel 5th is 0.76 which is the same as what I already have mate

you could always lower your fd to the 4.06 one and then use the ratio's out of the 1.4 cvh motors that have shorter gears 1-4 and put your .76 5th in that should get you what you want quick 1-4 and a slightly longer 5th for motorway
