The art known as choosing ratios.

I guess as Kev said you need to just try something either swap in a CTN or get a vr cog swap into your current box. I can't really make a judgement on how either choice will affect drivability without knowing accurate wheel figures. So.........

There is no magic solution, gearboxes are the compromise for the internal combustion engine. I think it is always going to be difficult to get the gearing right for a small capacity big power turbo car with FWD and not a lot of weight over the front wheels.
