I hate to say it, but I think your mechanic is trying to take you.
I pulled my 3.2 (same engine as your 3.3) down that had been boosted for years (at 1.2 bar), and the bearings looked brand new. It had no gouges or grooves.
The cam sprockets were worn out and the IMS bearings showed some wear, but everything else was pristine.
The speedo broke at 105k miles, so no idea of actual mileage.
Point is, there's no need to rebuild it, unless major oil leaks or bad leak down numbers.
At $20k, he's almost pocketing all the money as the parts will require very little machining at that mileage.
Seriously.
I'd get a 2nd opinion.
