I seem to recall reading somewhere that the TII oil pump flows more than the n/a oil pump, and that the TII oil pump is a direct swap onto an n/a engine.

Assuming the above is true, is it worth it? I plan on doing autocross and maybe the occasional track day, but it's not a serious race car. The engine (S5 n/a) is on a stand, and I plan on replacing the front cover gasket, so doing the pump would be easy while I'm in there.
