Well, it all depends on the Porsche. Porsches have always been about handling, and braking moreso than acceleration. Sure, a 911 Turbo may be fast as hell, but it also handles very well.
The 924/944/968, are quite similar in layout and characteristics to a Silvia, they are quick handling front engine, RWD cars, with a 50/50 weight distribution.
Most are naturally aspirated, with the exception of the 924 Turbo, which is somewhat rare, and the 944 Turbo, which is capable of power equal to that of the most highly tuned Japanese engines. Not bad for an entry level car
The 944S2 would be perfect for drifting, because of it's torquey nature, linear power curve, and excellent suspension.
