The same reason JGTC Toyota Supras were prepared by TRD with the 2.0 3SGTE engine replacing the 3 liter 2JZGTE inline 6, and with that 2000cc 4 banger producing 500 horsepower (GT500 class) reliably, it did hang with and beat those V8 modenas and V6 acura NSXs and mclaren v12's and whatnot. Why did they swap out the 3.0? because they could get same power from a smaller and lighter package, and mount it lower and further back in the chassis. in this case, advantage = small powerplant.
