I second what Oranoco said, and also cant see this being true.
The final drive on the mk4 xr3i is 4.27:1 as opposed to the RST's 3.82:1. So in the case of the car being identical in every way, the standard RST gearbox will give you 153mph @ 6500 rpm, whereas the xr3i gearbox would give you 137mph @ 6500rpm.
Thanks for your replies!
