To be honest, its not a matter of what next, its making the decision on where to stop.

Your car seems pretty sorted as is. Any small changes you make from here on in will not net much of a result.

Push for more power with a bigger turbo, to big and you go backwards from a track perspective (more lag, requiring FMIC etc). But then you will no doubt need to build the engine once it pops, or lunch your 5 speed.

Twinscroll conversion (VF37/36) and 6 speed with plated diffs would pretty much compleat the car imo.
