i believe it, actually. as has been mentioned, taller gearing helps a ton with that. my 2006 Tacoma will average 19mpg+ on a good day, and it's WAY less aerodynamic than a mustang.

Yes it doesn't get as good MPG as the other 4s but how can you even compare a high output highly developed and tuned 4 to a regular eco box 4.


I have a hard time believing in the 24mpg since my friends dad owns a Shebly GT500 and those things deff don't get good MPG. I do know the Vettes get in the 20s tho.

@OP
The S2k makes it power due to the stroke and compression but because of how it was design it doesnt take well to boost without being overhauled 1st

that's not what i've seen. i've witnessed numerous turbo/sc S2000s that are on stock blocks and make pretty good power with low boost levels.

back on topic: there is really no reason why they couldn't design the flat 4 that's going into the FT86 to behave like the K20Z3 or even the F20C (although i think the former is plenty good enough). there's not some magical wall that designers hit when cylinder layout is changed. it's all about having a good head, intake, and exhaust designs.
