fuel injector questions
 

so I'm kind of at a standstill. With gas prices rising and sucking hard, and the fact that my project car is also my daily driver, I have a huge question. I plan on using a volvo turbo with a 7 psi wastegate setting, for just a little boost. There was a post saying that 450cc injectors are good for 8-10 psi, so I figured a little small. My question, is what size injectors should I take, and exactly how much do you think this'll hurt my gas mileage? I know i'm probably gonna get hassled, "if you're worried about gas mileage, don't turbo" or something, but I'm a 19 year old kid who wants some extra kick with a dad who lives 6 hours away who he likes to see, so theres my story.

help me out

Run 7 psi, grab an FMU and stay out of boost most of the time.

Tell us more about your setup. You may not need to change the injectors that you have.

Re: fuel injector questions
 

Properly tuned, it MPG won't change if you run 400cc injectors or 600cc injectors.
The only difference it would make is if you need a peak of 200hp or 350hp. You'll eat more fuel at 350hp than you would at 200hp.

Around town, same power level, properly tuned, injector size makes no difference - you only squirt as much fuel as you need.

Improperly tuned, or just dropping injectors in without chaning your fuel map... well, yea.. it'll make a difference.

well I planned on running a 7psi volvo turbo, I have a probe smi, and as far as I know I needed 450cc injectors. I'm not sure what kind of ems i'm running because this is my first big deal and i'm making myself familiar with this stuff as I go. i have the stock d16a6 motor, and like I said just wanted some more kick.

I'm running 365cc's on my 4agte at 8psi on a T25, gets plently of fuel, so 450's should get you plenty o' gas I would say
