What size injectors and Fuel pumo would be good?
Hi i have a bone stock ls and i wanted to know which size turbo injectors would be good?Also which fuel pump would be best?Another question is what kind of oil lines should i use?Im planning on boosting 8 pounds for now but later on when i build my head im planning on boosting more pounds.

Re: What size injectors and Fuel pumo would be good?
Depending on turbo that should net you 300 ish whp. 450's would suffice but I'd recomend getting larger as 300 won't be enough power for very long it never is. If you have about 400 bucks you should get your self some id750's made by image dynamics. Sold by xenocron, t1 racing developement and a few others

As you'll inevitably learn through your time here on H-T, "pounds" of boost without a frame of reference means nothing. You may as well tell us you want "11" and we'll go about using that arbitrary number. With all turbo setups, you must decide upon a power level. The boost required to meet that power level depends on a multitude of variables therefore saying simply "11 pounds" isn't going to help us at all.
The standard answer for the pump is the Walbro 255 lph hp. The injectors are a tad more complicated however. To calculate that, you need to decide upon a power goal and then plan accordingly.
Lets say you're hoping to make 300whp, to calculate the approximate fuel consumption you would do as follows. The basic math is this, you need approx 6cc of fuel flow for every 1whp. If you're using E85, you must then use a value of 7.8cc / whp.
300whp x 6cc (per whp) = 1800cc total flow
1800cc / 4 injectors = 450cc
That means that a typical 300whp setup will require approximately 450cc injectors; however, this is an approximation and that flow rating would be near 100% duty cycle on the injectors. I know this is a bit convoluted, but it will make sense with practice. Basically, you need a set of 550cc injectors or so...

Just know what kind of turbo you're running and Steve will set you up with all you need.

Re: What size injectors and Fuel pumo would be good?
ur head isnt wat needs to be build ur block does head can just get u more air flow meaning some more power but ur block is wat is getting hit the most build block would be the safest thing
