whats up guys, just wondering how much mpg are you SI guys getting on the street and highway. And if anyone of you have the Greddy turbo kit on your cars whats ur mpg. thanks for any help

 

bump cuz i need to get a honda again...

 

I get about 21 mpg in city driving, about 28 on the highway.

As for the GReddy turbo, I am not convinced that is the best Forced Air Induction for this engine. I have heard some people have had some issues with the fuel management system and are not real happy. I am not up on the techical issues, but just read a few posts.

It is advertised as "bolt on" power, but personally, do not believe there is such a thing as "bolt on" Force Induction. I plan on doing forced induction the right way and upgrade any "weak links" in the motor before I slap on a turbo charger. I would also like to see a K-Pro system from Hondata before turboing as well.

 

thank you for the info. i'm really considering getting a si but i'm gonna wait for the sedan model to come out

 

I get ~26mpg with shifting at 3-4K. I vtec at least once a day, sometimes WOT, sometimes partial throttle
