5/6 Speed V8 Conversions

[Charlie Smith]

Hello all -

I'm trying to collect information about what really can be done
as far as Audi V8 manual transmission conversions.  The better
I can nail down and document what really fits what, it will help
all of us.

Let me start by telling you my suspicions.  I suspect that most
Audi V8's can be converted to a manual transmission with the engine
to transmission bell housings 'almost' bolting together.  I think
the bell housings will fit the engine block, with maybe a bolt or
dowel pin that doesn't line up; but with the majority of the bolts
lining up and fitting.

This leaves questions to be answered about pilot bearings, which
flywheels and clutch pressure plates, and which clutch disks to use.

As I collect information and pictures, I figure I'll try to put some
web pages together for future reference.  I'd appreciate any pictures
that people send me, either digital via email or I can scan and return
any real film pictures that show up.  I'll take pictures and measurements
of engines, bell housings, crankshaft ends, flywheels, clutch parts,
input shafts, and whatever people send this way.

As I've been collecting Audi transmission information the last couple
of years, I've come across various info and stories that will contribute
to this project.

Almost all of the Audi V8's were available in Europe with 5 and 6 speed
gearboxes.  The 5 speed versions, including the '91 we saw, all used the
type 016 Quattro gearbox.  This is the same gearbox used with (at least)
the '86 to '91 5 cylinder turbo cars.  (I don't know anything about
the non turbo cars like the 4000s, so I won't comment on them.)

All of the 6 speed cars, V8 and otherwise, use the type 01E gearbox.
When I say "all", I'm skipping over the sideways engine cars like the
Audi TT and all the VW stuff.  The 01E was produced in a 5 speed version,
but that was only used in the North American UrS4/S6 cars.

There are some other type Quattro transmissions, but I have not dug out
usage and details on them.

As far as I can figure, the bell housing in most 016 and 01E transmissions
are pretty close to the same pattern.  The clutch splines on the input
shafts are different, which means the a different clutch disk has to
be used.  There are some different (and incompatible) clutch pressure
plate combinations running around that I'll try to document.  I know
the '92 -> '96 UrS4/S6 cars use what's called a dual mass flywheel, which
is quite different from flywheels used on other 5 cylinder turbo cars.

As I get some web page info put together, I'll post the URLs.
