galaxy 1.9tdi auy engine 115bhp

[mercedes190d]

hi know the galaxy is irrelevant but it has the vw auy engine
dont have the power of my 130 gt tdi due to its weight and lower bhp engine
what i need to know can i change the turbo to a larger one like 130/150 turbo
and if so what else would need to be changed as i find it sluggish, comparing it to my golf
and as only reason for buying it was new edition on the way and need seats, and keeping my my mk4 gt tdi means buying one of these
so any advice would be appeciated

i need it to be quicker and more fun to drive.


thanks for any help guy's

I would recomend a remap rather than paying big bucks for turbos, intercoolers, injectors etc
