i was on a budget so i had to go with primarily used ...i found a fairly low mileage 99 996 engine which ended up being the replacement engine.
from my short experience with them i can attest to the mechanic's knowledge / experience / work ethic as i had several weeks of vacation at the end of last year in which i spent at the shop watching and asking Micheal (the mechanic) questions about the conversion process.... it was quite interesting and somewhat exciting for me to see the transplant taking place.
if you check their site...they do 3.4 / 3.6 and 3.8L conversions for the boxster.

unfortunately no there wasnt a BIG @ss boost gausge....that's probably why whomever had the car before me toasted the engine...heavy foot and no indication of possible overboosting....
