FAQ: Converting your Coupe GT to quattro

[StormChaser]

Audi manufactured the Coupe GT from 1981-1987. This was a fine car, with good handling and performance. It was exported around the world. In late 1984, they launched the Coupe quattro, this was essentially an Audi 90quattro chassis, floorpan and drivetrain, and a Coupe bodyshell top. However, it was never exported to North America, they got the Audi 4000q instead.

It IS possible to convert a GT to quattro. But here is what you would need to aquire to do the conversion (By the way, it assumes that you are starting with the 2226cc engine, and have 4x108 wheel stud spacing)

Front Anti-rollbar
Front Anti-rollbar drop links
Front subframe
Brake proportioning valve and mounting bracket
Exhaust Manifold
Exhaust downpipe
US code Gearbox
Gearshifter mechanism
Gearshifter boot, lever and knob
Clutch assembly
Propeller shaft assembly
Front driveshafts
Front-to-rear brake line
E-brake / Handbrake lever and boot
Center exhaust box
Rear exhaust box
Underbody heatshields
Rear subframe
Rear Differential assembly
Rear driveshafts
Rear calipers
Rear disks
Rear Strut assemblies
E-brake / handbrake cables
Brakeline T piece
Rear brake hoses
Rear screen (quattro script in heater element)
Rear side windows (quattro decals)
Gas / Petrol tank
Trunk / Boot carpets
Cabin carpets, front and rear
Fuel accumulator
Fuel pump and fuel pipe protection covers

Now you also need the lower front bulkhead assembly from a 4000q. The ENTIRE floorpan from the 4000q. You also need the trunk floor from a 4000q. Plus the rear inner wheel arches with the correct upper strut mount locations. From a 4000q.

AND you need a Coupe GT car as well....

Ok. So once you have all the parts, you're also going to need access to a frame rebuilding jig, as half the bodyshell has to be cut out.
Strip pretty much everything off the GT. Cut out the lower front bulkhead, the floor pan, and the trunk floor. And the rear inner wheel arches.
Weld in all the replacement parts. Repaint, and then all you have to do is to re-assemble the entire car.............

Also, check out the differences in the frames.

Now do you see why it's a stupid idea?

Thanks Dave.
Here's hoping I never hear that question ever again.

[beermonster]

I'm sure that you also forgot to say that it's a straight copy from the original page on my website at http://www.kvquattro.com/cq_conversion.html..........

[StormChaser]

Absoluetly true, copied wor for word, I totally forgot to give credit. I was SO ticked that somebody asked the questions AGAIN and never bothered to even do a seach that I did a quick copy/paste jsut to settle this once & for all. Very sorry for the lack of credit. Would you rather I jsut link to it so you egt more hits on your web page?

[beermonster]

No problem, just as long as I get the credit for it You're more than welcome to keep it copied in the FAQ section, which is a good spot to keep it. A link to my site would be appreciated however......

[StormChaser]

Done! Hopefully the question will never be asked again...

Once a month, at least, I said in the other thread

[Audi_VW_Porsche]

Why don't we just make this a sticky? Could really help people, I know people like to dream big but this is too much for the average weekend mechanic to do - and for those crazy enough to do it at least the are informed of the troubles before hand...

[StormChaser]

It's already linked in the FAQ at is stickied at the top.

You did not just say that If you don't kknow what the point of this thread is, I'm not going to tell you

[Audictd]

Your absolutely right, Canada received quite a few Urq's but this thread is about a different car completely......the Coupe GT quattro which Canada never got....ever.
As a test bed for the US market Canada gets a lot of cars that don't make it to the US but there was never any of these brought over.

These are a very interesting little car and I would love to see people do this conversion but........this thread is to disuade people from attempting it because it's so involved and most people just end up destroying 2 nice classic Audi's because they had high hopes of completeing this conversion.

This is not a project that you can do in your garage!!!!!!!

[91gti_wolfsburg]

Well, I've just acquired a CGT which has had this conversion partially done.

I did not bastardize 2 cars to make one, as the PO has already done so (professionally).

The car was originally slated to become an open class rally car, but the PO ran out of interest and time.

I will upload pictures as soon as I have them in a different thread.

[gt40mkiv]

Must..............see..............

[84cgtturbo]

Difficult...Yes. Impractical...You betcha. Cost prohibitive... Absolutely.

Impossible...Nope.

How bad do you want it?

Now THATS a NICE conversion.
I would have settled for the bodywork of the Sport though, I'm not a fan of the S1 flares and wing.... but WTF am I saying??
