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.
It would depend on the engine, transmission and rear differential ratio it has, need more info.
130-150mph? It would depend on how it is equipped with engine, transmission and differential gear ratio.
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
