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?
The final gear ratio in an xr3i mk.4 box is the one that will provide you with the highest top speed, just look in your Haynes manual, there you can see that the S2 has the box with the uppersit
