Replacement engine for 1999C4 needed


Recommended Posts

I had posted this topic in the DIY forum, but now think that was the wrong forum, since there has been no response.

Anyway, my original 3.4 engine expired a few days ago. We were driving along at a leisurely 65 mph in 6th gear when there was a clattering noise, some vibration and smoke. After pulling over to the shoulder as quickly as possible, and looking underneath, this is what I saw (photo taken from driver's side). BTW, this is a 1999 C4 coupe, 6-speed with just over 100,000 miles on the odometer. I have owned the car for less than one year, and drove it over 6000 miles without any problems until now.

I believe the chain broke, and was thrashed around causing the hole in the cam cover casting. The amount of internal damage will only be known when the engine is disassembled. I am not keen with the repair option, since this is a high mileage engine, and, frankly, I have lost some confidence with these early 3.4 units.

I am now looking for a replacement engine. There is now the temptation to install a more powerful engine, if I can find and afford one. I'm looking for advice/suggestions on what is involved in swapping in a 3.6, GT3 or 996 Turbo.

Has anyone out there done this? I don't expect to do the work myself, but I would like to know what I would be getting into before purchasing another engine.

Thanks.

Try the search feature. The question has been asked before but if memory serves me right the major challenge and expense has to do with electronics and/or the necessity of replacing the wiring harness.

GL and keep us posted on the progress.

Installing a 3.6 would require a DME change. A GT3 or 996TT engine is not really feasible (IMHO) because the base engine for those cars is different (from the 964-993 engine base). That would require changing the oil system, transmission and engine mounts.

Thanks Loren. That's what I needed to know. Maybe it's just as well that the GT3 and TT engines aren't feasible, since they would likely be too expensive anyway. I am now down to two options.
