[Es2] Audi 20v conversion

So convert from a 10VT to a 20VT, sounds pretty simple doesn't it?
Well I'm into my 4th year of finding parts that don't really make it, the
total of the parts that do, that cost more than the donor motor, finding
that if you really don't have fabrication skills....
Although I'm going to say if you're really up for it, a totaled 91 200/20V
TQ with a low mileage 3B motor, and it would be whole hell of a lot easier.
I got the same advice, but neglected to follow it.

Ditto on this! I don't know how anyone can suggest a turbo conversion,
10Vor 20 V being
easy and I suppose that is relative. It is one thing to install a larger
engine or higher compression with some fueling and ignition adjustments.
different when you need to re-engineer intercooler location and turbo
presently have my '90 Coupe Quattro dismantled awaiting such conversion.
conversion is made a bit longer process by my objective to do it clean and
the dashboard had to be removed and much of the interior yanked just to do
wire harness swap.
Integrating electronics "properly" will take likely at least 3 complete
days. The large
mechanicals(engine, trans, clutch) are a straightforward 1 man-week by
someone who knows
what they are doing and has all the correct parts in hand. On e a
one almost always ends up tearing down the donor, but not necessarily. Even
cleanup items, such as manifolds, fittings and gaskets take days. The turbo
portion can add significant time. My "ES-2" conversion is further
compounded with the
Ersatz nature and desire to install a 6-speed transmission and all that
entails, but if
I were only doing a "straight-forwared" swap from 7A to 3B or AAN, we are
less than a complete man-month from start to finish by one who knows what
doing, with proper tools and some help.
Do not take these projects lightly! Someday I'll document my now mostly
Quattro conversion - 10 valve turbo into 10 valve turbo with EFI
alone took my over a year to complete, although that was not all just
working on the
car, and much was ironing out bugs that ensued after the job was
"completed". That was
Phase I and II. Now it begins again with need to replace the turbo - sounds
you try it.
Feel free to take a gander at some conversion outlined on my site - these
are ones I
completed and documented years ago and will be playing catch up to document
the last 2
or 3 I've been working on. http:// www.gtquattro.com many updates

As someone with a 10VT in their 80 and former 20V owner I can say unless you
intend to track the car a 20VT is overkill. I would also suggest you
seriously evaluate your mechanical skills or bank account. The turbo swap
is by no
means a bolt in proposition. Lots out there have done it and may say it is
easy. If so, ask them how much they would charge for doing the swap on your
car. Getting the engine in is probably the easiest thing. Installing a
and intercooler, decent exhaust system is much tougher. Aftermarket EFI is
great choice, but nothing out there is a bolt in system. Lots of little
surprises and chances to screw up.
That said, the 10VT with low teens boost is pretty reliable, gets mid 20's
MPG and is an absolute giggle to drive. It will humble many cars and is
of the best all time sleepers. My 20V was plenty fast, but the turbo 10V
better power that starts at lower revs and pulls harder.
Feel free to contact me off list for more details. If you live near Bucks
County PA stop by for a test drive too.]

I am looking to possibly upgrade my 1989 Audi 80 Quattro 10v to a 20v.
Either that or
rebuild my 10v. What is a good way to get a hold of a used 20v. I also want
with a turbo, which engine is better for that?]
