well i'd like to be biased and say the supra would sin them all lol
but that depends on which supra model for a start and what mods each have if you say standard to all
1/4
mk3 7mgte vs rb20 skyline - supra
mk3 1jzgte vs rb20 skyline - supra
mk4 2jzgte vs rb26 - i think even really... even tho rb26 is 4wd i think... not sure... supra would take top end
rotary standard... yea nah lol
circuit
mk3 supra isn't really set up for roundy rounds... then again i don't think the skyline is either hehe so maybe once again even... possibly the stock power of a 1jzgte would take it
mk4 vs skyline... mk4 would take it... they're not too bad on the roundy rounds
rotary... i don't think it has the power really
drifting
mk3s were renowned for drifting back in the days but i think suspension change is needed
mk4s i think they're too stiff for drifting but hey it's been done
rotary... can't say i've seen them drift but i think rotary and mk3 supra would be pretty good together
i'm not an expert on all these cars but they all have their own advantages and disadvantages
its my opinion anyhow hehe
