It depends on your road conditions. If I were to use on plain highway I would recommend high speed diff, but if you belong to highlands low speed diffs are advisable...

It would depend on the differential gear ratio and engine horse power/torque.
Yes, if you change the gears in the differential that drive the axles and wheels. The lower the gear ratio, the faster the car will go with the same engine RPM. Example: A car with a 3.55 to 1 ratio differential will go faster than one with a 4.1 to 1 ratio differential at the same engine RPM.
Change the differential gear ratio and/or increase the horse power of the engine.
The gear ratio is 3.60:1, this is for the front limited slip differential.
130-150mph? It would depend on how it is equipped with engine, transmission and differential gear ratio.
It would depend on the engine, transmission and rear differential ratio it has, need more info.
It is a 50:1 ratio, that is 1 pint to 6 gallons
3.73
2.833 is the rear-end gear ratio
4.63
Limited Slip Differential 3.55 gear ratio
