How easy is it to fit the GTL differential into the R5 TS gearbox? I've never messed around with differentials. That sounds ideal even for a standard 1400 engine as the 5th gear as standard is lower ratio than the GTL's 4th gear.

Well, I wouldn't do a diff-swap on a standard 1400. I think it is just a bit underpowered. I actually did not yet make the swap. But since the TS gearbox is on almost all points identical to the normal GTL gearbox, a diff-swap has to be quite "easy". 130-140 hp has to be enough to take it to the 200+
