hows it goin, im alexr33, ive got an r33 gtst with quite a few mods done to it including full 3 inch exh with high flow cat, upgraded turbo, splitfire coils, k & n filter, heavy duty clutch, huge front mount cooler, running 18 pounds just to mention a few and im only getting 225 to 275 ks out of 3/4 of a tank, depending on how i drive of course. But when i got it, it was standard and i only got about 350 ks, so the more mods you do, the more feul she sucks.
