RB vs. 454
#22
250 mileage is decent for the size of the engine. Many 6 cylinders with like 2.5L in them guzzle like 20 mpg on average. KAs drink about 25mpg. That's what mine gets. on average. The lowest it's ever gone is 22mpg, and that's because of touge action :-D

heavily modded i would have to say that would be a pretty decent race. it would have to come down to the driver. you have to remember that the american muscle 454 with a huge supercharger is going to spin tires like a b!tch. even at the drag strip. and the skyline is going to get a better launch, especially if it has a huge turbo. gotta hate that lag. this is where the better driver theory is going to come into play.
