custom clutch - ie mating a audi box to a ford engine
Guys,
Thinking of doing something silly!
I can get my hands on a cheap audi transaxle & I'd love to use this in the next project (circa 2010). My problem is how do you mate the audi
gearbox to a non audi engine (ford 2.5 v6 or zetec for example?). IE how do you get a clutch / flywheel combination that will work ?

the lamborghini boys make an adpater plate to secure the bellhousing gearbox pattern to the engine block, then simply space the flywheel out the same
amount so the clutch is in the right place. i believe they use a6/a8 transaxles when doing this.
otherwise you could machine the bellhousing off the audi box and make your own, but could be costly and time consuming..

Mike,
Try this site for size!!
www.lambolounge.com/Chassis/Transmission/5000/5000.asp.
I think the Audi 5000 is translates to the 100 series over 'ere.

Might be missing the point, but do you already have the Ford engine as well?

hi, im doing exactly this - mating an audi 80(a4 - same) transaxle to a zetec. ive got the main parts and im literaly off now to measure if the audi
trans has the same mounting as a hewland mk9 (same as beetle) if it is (or thereabouts), adaptor plates are easy to get so all sweet. if not, but of
noodle scratching but sure will get there in the end. keep you posted but let me know if you have any brainwaves.
earlier measeremets showed there may be issues with flywheel diameter and clutch size etc, but sure well get there in the end.
atb,
zane

beware that vw engined a4's are tranverse, only the larger audi engines are inline with a transaxle..

There are a lot of autograssers using various engines with the VW transaxle, usually the transporter one, so worth a post on the yorkshire dales
autograss club forum

Sounds like a blinding way to separate flywheel from engine... with all the fun that can entail at 8000 RPM!
Although presumably they run big power with this setup so it's ok to do?!

james, if you were that worried, simply get a new flywheel machined to a custom size from a single billet, then it should be strong enough, just
perhaps a little heavy, unless made of ally

thanks ns, will have a look for any pearls of wisdom. measured it up and fitment nothing like beetle (hewland mk9), so back to the drawing board on
that one. lambolunch looked interesting, could make own like suggested.
on another tip, my transaxle came out of 1.6 audi 80. its the same as 1.8/2.0, so not too worried about power handling cap. thought all a4 were same
too, but may stand corrected.
cheers,
z

What are you building wheels? Something mid-engined? What about using a quattro g.box and building a 4x4 locost!!

If you post a question on the yorkshire dales forum, someone will help you! I know Derek Tinson in our local club runs a 210hp Vauxhall XE on an Audi
transaxle, as I race against him regularly!

well i just won my ebay auction,
1 1997 audi transaxle from a rear end smashed 1.6 a4 circa 66k miles with clutch.....
total cost........ 99 pence! just got to organise collection from star city (huge 40+ screen cinema) or birmingham footy club (does that sound dodgy
or is it me?)
hmmm, do you think he'll accept 100 pence instead of 99? and do you think he'll insist on payment by cheque before we meet up????

Sorry Ned, all A4's have longditudinal engines
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

99p!!!! now thats a steal. payed a hefty 45 sheets for mine, though the bloke was trying to convince me it was worth £400!! great looking box though,
cant wait to put it use.
as for what its going into, its the next project (think ned posed in another section about buying bits ahead of time - hows this - a project ahead of
time!) cant reveal too much yet as its a bit of a lucky find, but its a middie and a stunner. only building drivetrain now, rest to follow. sorry to
be secretive, will keep you posted as soon as shes actually mine and in the workshop.
have posted on the dales autograss forum, next port of call after here. also found adaptor plate on ebay, but for standard 4 bolt vw pattern - anyone
know if same?

Mark,
Thanks for correcting me, I'd been lead to believe that vw engined audi's were transverse, oh well..

Just stumbled across this thread I'm following the same route. Trouble is the usual transaxles Renault, Audi or Porche (for rich people only)
have the input shaft from the clutch higher than the output driveshafts.
Suppose thats because the saloons they are based on will have occasional forrays onto verges etc but we want a low center of gravity and dropping the
engine transaxle down to 70mm ish ground clearance makes the driveshaft angles mince.
Hewland and similar boxes have the input shaft lower than the drive shafts avoiding the problem - at a cost.
Easy I thought just turn the box over!! Simple - apart from 5 reverse gears.
The Renault UN1 box as fitted to the Alpine (rear engine) would do nicely as the diff is fitted the other way round. But they are not so available
and to take decent power need the internals upgraded at £2.5k - too much for me.
To the point at last! Can the CWP be fitted the other way round on the Audi box so I can run it upside down? Looks possible but without one to play
with I can't tell. Anyone fancy trying?
Cheers
David

Forgot to say anyone tried the same thing with the UN1 box? i.e. reversing the CWP?

not sure about cwp (take it that stands for crown wheel pinion?) on audi, but on a practical tip managed to get oil everywhere whilst cleaning the
underside, leaked through the breather. be sure to seal before mounting!
im such a dumbf**k sometimes

the diff in the UN1 can be turned round for rear engined cars like the delorean,alpine etc , a chap a GTO engineering in reading rebuilds them with a
quiafe ATB diff aswell . his name is kev turbo !!
we used to turn hewland boxes upside down to get a better driveshaft location for darrians . how much power do you intend to put through it ?

400hp and 400lbft torque. It's looking as if the Porsche G50 box is not as dear as it first appears - it works nicely upside down, the
clearances are OK and loads of other chaps have sorted out the problems with smaller diameter flywheels and starters. Its just pains me to part with
the cash.
Cheers
