Hands down the skyline-34 w/ its four wheel drive would out perform a rustang, stock. And most certainly on a road course w/ attessa suspensions and such, instead of a rear wheel, running more torque than it can handle, especially in tighter turns. On the 1/4 the GTR34 has a stock 0-60 in under 4.7 sec, and a quarter at about 11.9 sec average.
The rustang GT, roush edition runs 4.9 seconds 0-60 stock. A quarter-mile sprint in 12.7 seconds. The skidpad performance of 0.96 g to 0.98 g with the standard tires. Premium version, costs $48,975 (According to Autoweek)
Honestly, whats better twin turbo(

) or supercharged with a 5.4 liter gas gussler. You will get better and more performance from a turbo charger than a super.
If your talkin moded, then there is still no comparison when a skyline 34 in NZ ran over 214 mph, and 1338 horses, stage 4 turbo system and such. If the rustang beat a 214 land speed record (1 1/2 years ago) then show me figs and sites then I will stand corrected, but until that day GTR will remain supreme.
I must say, the skylines in this forum are beautiful mechines. I envy those who drive such a magnificant automobile. Looking at doing a gtr-33 as a project car. Yet, we will probably wait for Jap spec GTR-35s in Spring of 04'.

That 87' Rustang wanna 1/4 me with 2.0 bar boost on a 240sx, TT, mounted into a 1990 Acoord. (Will have pictures soon)
