As always, when something breaks it is a great opportunity to upgrade :) In the case of Nirwana's motor, it is getting some fancy heads which are strengthened, ported, polished and with bigger valves, more agressive cams, and solid lifters (rather than stock hydraulic lifters).
The big upgrade is conversion from 3.6L to a Porsche Motorsports 3.8L capacity with all the Motorsports upgrades for better lubrication and strength.
On top of that, the turbos are upgraded with the latest Porsche GT2 compressor wheels!
I have no clue how much power this will make and what the drivability will be like, but is sure sounds promising.
The downside, other than cost, is that it won't be finished until August/September. This means the Boxster will have to handle track duties until than; the plan was originally to do track duty only thru June. More on that in another post.
Here is a picture of on of the six cylinder heads:
