first of all, f-1 cars use either v-10 or v-12 NA motors revvin from 9000-12000rpm constanly, second of all, cart cars use a v-6 with a massive turbo. just a question, have u guys seen the new Infinity G35? watch the commercial and look at the V35 sedan, u should see that it is pretty much the same car....just a little comment on my end...
the skyline should keep the RB motor, thats what made the car famous.
