Supercharge or Turbocharge that FSI???

Could be done but not simple or cheap - especially if you want the engine to last, and it still has to pass emissions testing at MOT.
Basically when you turbocharge you need to reduce the compression ratio, the turbocharger makes up the rest. This means mechanically changing the engine (e.g. spacer between block and head or different pistons . . . ) and hence a complete re-map and potentially lots more changes like a bigger radiator, clutch, gearbox, brakes, and for the weight new springs/dampers . . . . . For example VW 2.0FSI has compression ratio of 11.5:1 but the 2.0 Turbo is 10.3:1.
Probably cheaper and easier to look at putting another engine in (e.g. a 1.8T or the new blown 1.4)

If you can fit a 1.8T in they can be taken up to 600bhp!
Would need 4WD as well though!

I'd be interested to know what difference a remap makes - not necessarily in terms of power but driveability - especially if remapped to 98 octane fuel - it might make it even rougher on 95 but would probably feel much smoother when run on the proper stuff. The factory map will be written to make it run OK on both and also it won't take account of the individual differences in components etc. I wonder if we could get a group discount, its too much money as it is.
