Boxster Subaru conversion interest?

I don't know. This might result in the same thing as a "lift throttle" mid corner, inducing a spin. The basic rule with a 930 or 951 is: When the car comes on boost, make sure your steering wheel is pointed straight... even if you are mid-corner make sure the wheel is pointed straight.

If it was my car being built, I would favor a wider, fatter powerband and give up some top end HP in favor of drivability. A 997TT is really pretty good here and any turbo motor could be tuned for drivability. Everything is a tradeoff.

I am seriously toying with the idea of building a turbo capable Subaru EG33 (3.3 liter flat six cylinder) and swap it in using the same turbo as what's in there now. More torque, more linear power, and faster spool. The down side is the engine is heavier and longer and parts aren't as readily available.

Nah! Get this one sorted and see where she is. Every car has it's own personality and you just have to adapt your driving style to the car. With my car and a stock 2.5L I have to maintain corner momentum and get on the gas really early on corner exit or I am dead meat. With the Boxsubi, you can drive it more like a Viper... Easy into the corner, get the rear really settled on exit and then hit the hammer. You can afford to wait on the throttle a bit because there is so much juice available.

I gotta be honest. When I saw you were putting a STI motor in there I had visions of wiring harnesses hanging everywhere with splices and electrical tape, and two shift levers sticking out of the dash. So many projects like this end up as science experiments gone bad. I am totally impressed though. I had a hint you would put it together well because I had seen some of your Boxster Spec exhaust fabrication and I knew you were pretty handy with a TIG. Stay the course. This car will turn out great.
