Well John here is the fastest all motor 13 second 5th gen Accord. Given the 5th gens pull around 17 seconds in the 1/4 I'd say thats a pretty big gain. You get around 70 extra ponies over stock. Do some more internal engine work and you'll open that up a bit more. Turbo is all fine and dandy but a lot harder to maintain, and nitrous... it makes me laugh... must be because its laughing gas.

Personally I am not looking to be the fastest all motor 5th gen. I am looking for the all around fun factor. One day when I have more money I hope to get certified and race cars.
