For good power and still use it every day I would look at the elimiater kits if on a budget or go full GT28RS or full GT2871r you can still run them on the ECU just need to find the right software for the set-up you go with. With these set-ups you will see around 300-350bhp at the wheels; also drop ain set of rods and pistons, scat rods are good and cheap.
You will need FMIC for sure and uprated brakes not to mension all the other hardware.
