Might want to run a search, there have been post about TB's and such. From what I've read you can bore your TB and get some alright gains, but somewhat increase in throttle response.

Searched and got this. THis is suppose to be about the same size as the Skunk2 TB

Bore intake side to 70 mm /manifold side to 62mm for the GSR TB
