I think you will find the only difference between a 3i box and an S2 box is the LSD so if you use a 3i box and sepnd a wedge putting the LSD in you will in effect have a stock S2 box
And it won't be any tougher. The standard S2 ratios are good for 150mph, how quickly do you need to get to Tesco's anyway?
