JB:

I would not worry too much about the new engine but I would be really worried about the instalation. There will be many parts which need to be removed from the old and installed on the new. At the very least, the intake, fuel injction, altenator, clutch, gaskets, etc etc. At worst the heads or other major engine components. Mechanics get paid by the job and warrenty pays less, for most manufacturers way less. If the mechanic knows he can't do the job for the pay, and maybe he lost out the week before for the same reason your going to get a bad job. I just got my 997 and so far the dealer has been good.

The dealer told you it will take 5 days to install! Wow, you know they won't be giving a mechanic 5 days to do the job.

Good luck.
