Hi. I am trying to plan ahead for the possibility of having to put a new engine into my 99' C2 6spd. and I would like to know if it is possible to correctly fit a 01-03 TT motor in there. If so what might I need other than the harness, brain? The problem is I absolutely love my 99' and well it sometimes makes me worry reading these horror stories about failures. Mine has a dry start tap like the lifters for the first 2-3 seconds and one independent knock sounding like one rod bearing sometimes lasting up to 8 seconds. Allthough the knock is seldom heard, it is nonetheless there. I know the chassis are prettymuch the same less some stiffening, but what is the difference in the widebody and are all turbos the widebody? Oh yea and will my 6 spd mate to it? Many Thanks! :drive:

You would basically be building a GT2 since your car does not have 4 wheel drive. A 2WD Turbo/GT2 is a handful even for an experienced driver (IMHO).

I do not know if the intercoolers will fit under narrow body rear fenders.

Other concerns would be a fuel delivery (TT has always had the returnless system that your car does not have) and cooling (needs larger ducts and radiators).

Might be an easier project in a C4S but a narrow body would have some real challenges. All IMHO of course...

I agree with Loren.

Also, the transmission casing will not match up to the turbo engine. The Turbo crankcase is based on the GT1 engine, and is different to the M96 engine/transmission interface.

Hmmm, well I'm thrown by the fuel issue. But the rest I sort of figured I would hit a snag on. With all the little problematic 996 failures and the things I would like to do with my C2. A TT engine is/was a definate possiblility I have been pondering a SC, and with a 75kmls 3.4, I have become a little fearful after reading through here, and also a little lucky that my engine has not imploded or something or other by now. Anyone know where I can get a GT1 engine-tranny? J/K! I appreciate the knowledge. Does anyone know of anyone who has transplanted a newer/better engine into their 99-01? I guess I'll spend a little time looking through my Porsche Manuals about those differences. Many Thanks!
