I put a 300D turbo engine in my 240d with a manual tranny and the front end dropped ALOT. It handled awsome though, then I blew the engine.

Fuel regulator or shut off valve or whatever went while I was haulin ass and the rpms went through the roof, car wouldn't shut off, cars redlining, panic ensues, black smoke is billowing out the back. I think it might blow up or something so I run across the street and watch her DIE.
She started back up and got me all the way home, 30 miles and never ran again. Thats a real car.

I'll have another soon though.
