I know this isnt tech the right forum for this car but the ST forum on here doesnt get used much. Been dealing a lot with Alex and Wayne at Pro Alloy getting some power steering tanks made when they said that they needed an ST to see if the new MK2 RS intercooler fitted.

So dutifully i lent them my car and low and behold they made one to fit. The pipe work sizes are completely different to the RS and so was the angle for the outlet.

Heres a couple of pics, i would post up saying what bhp difference its made but recently ive had problems with a slipping clutch and an incident with a roundabout.
