2.5 rotex supercharger from jamspeed gives you around 70+bhp with a good exaust system. 3.5k to buy but you get fmic hoses.

Mountune do 185bhp package for 2-3k

If ypur gonna go down the forge pistons id strongly think about turbo. Its expensive but your looking 300+bhp. I was talking to aguy from jamspeed an his mk6 st is 500bhp. Turns it down to 8psi for road use

With them mods 180 would be achivable. Id get a sports cat on the car. Still be able to kind of pass the mot then

The supercharger is expensive but if you look around and get lucky it probably will be a lot cheaper.

Was one up on eBay for 1500 not sure if it's still there though.
