No need to worry about the TB. It will flow more than you will need.
Here's some tech info that I borrowed.
Figures are calculated using 146CFM/sq. inch flow rating @ 28" water depression
60mm 99^ 3.8 TB stock: ~501.8 CFM
2.362" opening, with .400" full shaft (standard)
4.382 sq" less .945 sq" shaft area
3.437 sq" WOT.
This means that the stock TB will support some where around 300 hp.
