change the final drive and get a clutch type LSD > type R gearbox in terms of the performance (LSD) and the cost

Myth is that ur top speed drops if u switch to 4.7fd in the ITR. Only the first 3 gears are shorter, 4th and 5th are exactly the same as the 4.4FDs

Glocker, in the ITR box first is the same as the c2 box albeit shorter final drive and only second and third are shorter

N/A - stick to a dc2r box.
FI - go the dc2 with a 4.4 FD and drop in an LSD from the ITR.
I got 205km in 4th gear at 7.5rpm with the dc2 box.(Boosted)
There is a noticable difference in the ratios and again with the FD

oops, 2nd and 3rd is shorter, the rest are exactly the same.

if you are going to boost, C2 box with aftermarket diff, no point sticking to the stock ITR helical one
