Which Audi FWD gearbox to use in a 400BHPmid engined configuration?

[Error404]

Fair enough, if its in keeping with the car. Otherwise it seems like an expensive and long way round to do it properly, dropping compression, forged pistons, custom manifolds etc when OEMs like Audi and Nissan have already done the hard work for you. Sounds like a cool project - do you have a thread running?

Sounds like a 6r4 replica brewing to me

There was certainly food for thought in your suggestion & I appreciate where you are coming from.

I still need suggestions for a gearbox though!! That said, I may opt for the 1.8T box and carry a few spare ones in case of failure..

Only doing RWD? Iv been thinking of doing a similar project, one idea was cossy running gear with lengthened front prop to front wheels.

I have an 80 coupe box sitting for similar plans if you need measurements.

I've been juggling 4WD ideas for a couple of years, in order to make it a little more authentic, with the correct rear facing engine. It could be done, but would be quite complex. So I've settled for a stress free life & RWD. It will be fine on tarmac.
I measured an A4 box this afternoon, but thanks for the offer anyway

If it's a 6R4 forget the turbos and go for 9k rpm!
Will you be racing the car or just road use? I think you'll want longish ratios from a TDI box or you'll struggle for traction with 400lbft and RWD in a car that weighs so little

BTW not sure if you know already, Tonks4x4 on the forum is doing an Audi powered 6r4, he is out your way in Notts

Yes 9k rpm would be very nice!! Mountune do the Jag V6 to that kind of spec without turbo's for somewhere north of £10k.

The car will mainly be for road use, but maybe with the odd sprint type session. I hear what you're saying regarding ratios & power/weight etc. That certainly makes sense going from my experience with Yb Cosworth powered cars.

That's reason I planned on using baby quick spooling turbo's, so that it isn't too far removed from a N/A engine in it's characteristics, and make some use if the V6's natural grunt.

I guess the thing with these Audi boxes is, they're cheap & plentiful, so swapping them & playing with ratios isn't too much of a hassle. And I can have lots of fun trying to break them too

Yes I know Brian & the 4 wheeled shenanigans that he gets up to!
