Hey guys, i was wondering about how much aftermarket injectors are going to affect the fuel mileage on a SR20. I'll probably be getting 555cc or the 740cc, i havent really decided yet. So about how much would it affect the mileage??? thanks...

Wont effect it at all as long as your not flooring it everwhere you go. I still get 30+mpg on the highway if im not mashing on it. Im running 555cc injectors.

It's really hard to not floor it though. I think the novelty of boost has still to wear off for me.

I need to drive a boosted car in Winnipeg. the cool temps would probably make me more of an addict than I already am.

My BOV is uber loud when Im boosting above 5 psi. And I love the sound of it. So in every gear before I shift, I am boosting well over 5 psi.

I didnt slap on all those upgrades just to save fuel... no... I did that so I can be pushed back into my seat.

If I were worried about MPG, I would've gotten a Prius... not a SR with 2871r
