Answer
Both are great cars and you always see them up against each other on the net,luckily being both great cars and man
y owners switching from one to the other so much respect is given to these cars from each other.
both cars offer great tuning engines and as we know that in japan engines had to be below 280bhp as because of this skyline supra and man
y other japanese cars left with speeds higher than book says and of course there engines being tuned down but able to run at there actual power once released.example of this is the skyline rb engines actual running of the engine is around 500bhp on stock internals and iam sure the supra will be with similar figures,and there engines with mods can reach over 1000bhp as we know.
the awd would def help in a race,but as said on these cars it is
tit for tat as what ever one can do the other can do to match
it so i would
depend on the day,and i can imagine if one won one race you other would win the other.
