I have an 84 Coupe GT with an automatic transmission and a 82 Coupe with a manual. Anyways, the 84 Coupe GT runs really well, but the body is in horrible condition and I doubt that it will pass inspection (not to mention it's an eye-sore). The 82 Coupe on the other hand does not run, but the body is in excellent shape (compared to the 84 Coupe GT, that is) and as far as I know, the transmission is still fine. My question is this: Is it possible to swap out the engine from the 84 Coupe GT into the 82 Coupe, and use the 82 Coupe's 5-speed instead of the 84 Coupe GT's automatic, or am I gonna hafta take the automatic with me when I do the swap? The reason why I ask is that with a fair number of Hondas at least, the engine/tranny combos are practically integrated as one peice and are an absolute nightmare to change from one to the other, so you more or less have to take whatever tranny that is stuck with the engine you are switching (unless of course you want to go insane, hehe). Just wondering if this was the same with Audis. Thanx Folks. :)

you will need to have the pilot bushing changed on the crank to a pilot bearing...
i would take the engine to a machine shop for this...
make sure you change all the seals while you have the engine out.. MUCH easier at this point in time.
Valve cover gasket, thermostat, injector o-rings/seats...
maybe some new plugs and fresh antifreeze...
you'll be good to go :)
might have to swap the water pipe at the back of the block and use a fresh o-ring while doing this as well..

Not realy true even hondas are using the same cranks it would cost too much money to make a crank for auto and a diferent one for standard but like the hondas they incert a centering rinr in to the back of the crank for the automatic so the torque convertor would be centered, to put a standard trany on it you have to pull it out.
Not sure if audi has a centering ring but Im almost certain it does so you have to pull it out and press in the pilot bearing for the transmition input shaft,everyting is the same.

Not that hard, the prev post from Rich is basically right on. I put an automatic motor in my CGT to a 5 speed, had to change to a pilot bearing. Getting the bushing out of the end of the crank was a major PITA. I was able to do it by cramming as much axle grease in the hole as possible and pounding a metal rod into the hole wrapped in a rag forced it loose. Several hour job, though. After that, just change the flywheel and you're ready.
Not sure about the heater hose fitting between those years, it may be the same. Easy enough to change with the engine out.
Definately the time to replace the timing belt and water pump, gaskets and seals, heater hoses, etc. It's about the only chance you'll have of replacing the air filter with a minimum of knuckle scrapes too.
This is a big job. The whole thing drops out from the bottom as a unit (eng/trans together). Neither one is light! Begin spraying the subframe bolts on your good car TODAY with WD-40 and every day until you do the job, then remove them by hand and not an impact so you don't snap them off. Buy new subframe bolts; DO NOT re-use them (ask me why).
If you start this project keep my email handy, I'll be glad to help you with any probs you encounter.

Well thanks for the info! You folks are a true wealth of information...just like superhonda.org, only a lot smaller and more direct and to the point. :) I'm definately gonna go for the swap.
