so id like to turbocharge my o3 honda 400ex. the turbo plumbing pipe work isnt the issue at all. what is confusing me is how am i gonna fuel this ***** once the turbo goes on. so im wondering if theres a way to run an external boost dependant fuel delivery system of sorts or if id have to change over to a fuel injected setup. ive been searching google for 2 weeks, thought id ask here :)

ive been diging around, looks like a throttle body and computer with fuel injector setup is the way to go. but these things are damn hard to come by. anyone have any info on this?

you may be able to manage getting a efi system off from another quad onto your 400ex. i have never heard of it being done, but it sounds rather interesting.

ive seen a handful of turbo 400s on youtube and there was even a writeup in an atv mag a while back about it but the mag is now offline for whatever reason. my understanding is that with the regular carb youll end up breaking things internally under boost so a blow through carb is needed. but i bet that an efi setup from a shop is gonna be worth close to a grand. here are a couple setups ive found for sale but i havent heard anything back about either. so im thinking if i dont go turbo i might just put a small shot of nitrous on it :D
