Just curious, what gains in performance are there from a lightly modified standard turbo car? I have a friend with the following mods who wants e85 but I think the money is better spent elsewhere... Anyway:
Eg rb25 with standard turbo, 12psi, standard motor, pod, fmic, nistune, 3" exh etc?
Making around 190-200rwkw, could he expect the same increases in power as someone with 300rwkw going from 98 to e85?
