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

 

ride a bike instead.

 

figured if I got hated on, i might at least get a little bit of help too

thanks.

 

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.

 

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
