[Mr. Tweek]

It's hard to compare two cars that were never meant to be compared. They're completely different from one another. One has an all wheel drive set up, that is if it's a gtr, and a 2.6l twin turbo. The other is rwd and has a 3.0l twin turbo. That's almost half a litre difference. Either one can be faster than the other depending on the car's weight, wheel horsepower, and the driver. i don't believe one car can ever be "fully modded". Then what is the race? Top end? 1/8 mi? 1/4mi? Race course? I think the best comparison could be made between an R33 series 2 gts with an RB26DETT swap and a MKIV Supra with a 1JZ-GTTE. Although the GTS Skyline never came stock with an RB26 and a MKIV never came stock with a 1JZ. Almost direct comparison though: Both rear wheel drive with lsd, roughly same weight, series 2 r33 came around in 1996-1999, around the last days of the US having the Supra, and finally the skyline having a 2.6L TT and the Supra with a 2.5L TT. Point 1 L difference is much better than .4. Although the Series two came with a 2.5L stock on most occasions(rarely a 2.0 inline 6), it's a single turbo. So from a dig to the top end, completely stock, supra would most likely jump the line, skyline would lead up to around 120 or, and then the Supra would take top end.
