I heard somewhere that there is a larger master cylinder that fits straight on the 5's off another vehicle, im sure it was 306 non abs but want to see other peoples experience, if anyone knows anything regarding this please share:) thank you

It was the mk 2 gti.

I think the part number for it from gsf is 652VG025 but would need to double check

172 or 182?

Either mate, think mines off a 172 cup (non ABS), steevo may confirm if he's around.

oh i see, ive just been doing a bit of research and the gt cylinder is 19mm diameter and the golf gti 22.5mm according to gsf specs, so in theory sholud move more fluid with less of a push, worth a try i think.
