if i upgrade my injectors on a turbo II...will my gas mileage be effected alot? and if so how much..im guessing it depends on the size correct?

 

Yes it will be affeted and yes it depends on the size

Power = bad gas milage

Shouldn't be horrible but gas milage on these cars always sucks.

 

If you simply throw bigger injectors in it'll run very rich, use lots of gas and loose power, because the ECU will have no idea that the injectors are not stock. You need a fuel controller to tune the mixtures back to where they should be. Why do you think you need bigger injectors?
