just bought a 31 for my s2 erst and just wondering on the shaft does it have to be a different lenth to the standered one or just measure so it the same as the standered one.
i bought it cheep of my mate and just wondering will i see much bhp difference on a standered lump.

 

an uprated actuator wont give u "more bhp"............. .........if the one on ur car isn't broke..........dont change it.........

 

i only payed a 10,er for it so it not so bad so what's the point of a uprated one then? i thought it held more boost = more power

 

...........u need the uprated chip/map...(.injectors....turbo).........aswell..... if u try winding the boost up without the relevent software it will go...............................BANG!!!!!!!!..... ..............
