Next turbo size up from stock S4?

Anyone have an idea on the next size up turbo after an S4 stock?

Want to get a little more power, and hopefully a BB turbo...

A hybrid, probably a U-trim T04B. You won't get a ball bearing in a hybrid though.

Actually, the "next" upgrade would be simply to an S5 turbo. You start going much beyond that and you're getting into needing upgrades to fuel, injectors, and ECU.

That's not a problem, carburetor powered.

Not looking for any internal wastegate turbos.

57trim To4E is the smallest entry level turbo I would recommend. Makes 400rwhp between 16-18psi. In t4 trim it is a free floating turbine housing( no internal wg). With a nice divided turbo manifold and free flowing exhaust spools just as fast as a stock T2..
