Stripping the front end off a Treg seems "relatively" easy. I wonder how many of the "engine out" jobs on the V10 (and the R5 for that matter) can actually be done by just stripping the front end in stead of taking out the engine...?
For instance, the famous gear driven alternator, a/c and water pump...? Maybe even the turbo's...? I'll definitely give this a try first when the time comes to replace the elastic drive couplings on my R5 (150k km).
