the golfs even with the 130bhp engine are nice to drive both 130 and 150 can be easily taken to 200bhp without too much problems. as long as they have the PD (twin pump or common rail in most terms) engines fitted like HDI said dont try the SDI engine as there is no turbo fitted and youd be better going and gettin a push bike
have a look at
Do you talk power or drive torque
to see what HDI is on about BHP and torque being related to the revs
if your really bored read below
the skoda fabia vrs uses the same 130 engine as the golf go on youtube and look for fabia 260bhp ( very smokey )
