Forced Induction for 2.5L Boxster

I've done what research I could in the past few days, and have seen that TPC Racing makes the best forced induction kit. However, I haven't seen anyone install it on the older 2.5L models (the one I drive). TPC Racing's website also seems to be down.

I was wondering if anyone could point me in the right direction.

There have been a few success stories but FI in a 2.5L Boxster has generally resulted in scattered parts and connecting rods sticking out of places they didn't belong. The chief problem to overcome is a very narrow tuning window running 11:1 compression ratio and pump gas. A much more successful path to hp has been the 3.4L motor transplant. It is everyday drivable and as reliable as the stock motor with 100 extra ponies.
