Over the years i had a few gtrs, the closest that comes to mind was a 95 model v-spc, only mods full exhaust ( stock dumps), power f/c and ebc running 14 psi on stock turbos. She did a couple 12.3 down the wsid 1/4 . Another 33 ( none v-spec ) with the above mods + N1 turbos, stock dumps even stock airbox, she ran 11.7 @ wsid . Not difficult to run high 11's in a fairly stock gtr, much easier than a bommie and you can put the power ot the ground . I recomend you invest in a pair of turbos though, thats the weak link in the GTR's because they are ceramic wheels and not because of the size . Rb 26's are very strong and durable engines and in stock form will handle up to 450 p.s. at the flywheel, keep in mind they are only 2568cc not 5700 like the bommie .
