SR3 Engine Choices

[Camalga]

I am new to this forum having just acquired a SR3 with a 1300 turbocharged Busa. Unfortunately having made some impressive lap times on various circuits No.2 piston made a bid for freedom through the crank case in the warm up for its maiden race in the OSS series. Prior to that the previous owner spent a fortune on the car with various upgrades but got bored after the engine blow and has now moved on to GT3. The car is now in my possession along with a load of extra wheels, body panels and other parts.

My question is what to do next? - source second hand Hayabusa and transfer over the turbo, dry sump and possibly cylinder head (thats still good); go for another spec of engine; dump the car to the highest bidder; etc

I am no racer so would only use the car for the odd track day. Whilst happy to undertake most mechanical tasks myself, an engine rebuild is beyond my skillset so would need a pro to get involved if I go down that route.

Any advice appreciated
