I had an 82 245T, non intercooled wagon. My friend down the street owns it now, and it's now intercooled. I just helped put a new wiring harness into it from a 1984 donor car.

I've also got an 84 242, non turbo, and had many others. There are significant differences you'll have to overcome to turbocharge the car and get something you can drive.

The engine's not the same. It's got high compression pistons. How will you deal with regulating boost so you don't cause detonation?

There's no oil return line in the block. Are you prepared to drill the hole, and drop the oil pan to get the chips out?

You need the exhaust from a Turbo. Nothing else is going to work. You need the special upright Turbo cat. The back end of the system is larger as well.

You need the turbo intake manifold and exhaust manifold. You need all the intake plumbing. You need the intercooler, longer clamps and different shorter fan shroud if you're intercooling it. I'm not certain if the wiring harnesses are different but it looks to me like they are. The position of the throttle switch and sensors may not all reach to the right locations. There's an oil pressure sender that's not in the regular models, for what that's worth.

It's not a simple or small job. For the extent of work it's going to take vs power achieved, I'd say go with an upgraded cam and enjoy that; this project could turn out to be a nightmare.
