Okay so I'm wondering if I should upgrade my injectors on my NA build reason why is because I and going to removing them on work I'm doing so why not change them. Been searching and havnt found a solid answer on what are stock size injectors are "cc" seen people claim 280-330 cc. So anybody that is sure of the size and also what size should I uprade to on my NA build if its even going to help.

Also thinking on getting one of my maps tuned to e85, again if its even worth on a NA build! I am just about fully bolted expect headers

So I need some feedback on what I should get if I should even get them. Staying NA but trying get the most out of the engine HP. I'm getting the lower collector port matched along with upper and lower plenum with my new NWP TB.

So what have you NA builds done as far as injectors if you even changed them. Any and all feedback would be great also a new thread to help other with same unanswered questions

But here are a couple pics of my lovely G *iphone pics lol

 

If by "NA build" then you mean doing some bolt-on's and making it look pretty...then no.

 

planing on putting in cams and doing motor work but staying NA which is why im wondering if injectors would help since im going to be pulling them out. just saying so far all i have is bolt ons

 

Even with cams you're nowhere near needing aftermarket injectors.

 

do you know of anyone or people running e 85? this is also a reason why i was thinking of injectors. but thanks for the help

also any idea of what size our stock injectors are?

 

If you want to run E85 you'll have to upgrade the entire fuel system... not exactly cheap

 

fuel rails, pump, injectors, and tune right?

 

E85 is corrosive, so if the OEM system wasn't designed to handle the E85 then it won't handle it very well... not to mention the additional flow that will be required to make power with E85

 

e85 isnt worth the cheaper pump prices... figure out what size the oem injectors are... if they are ~300cc, then they will handle ~365whp on premium pump gas... cuz 4 370cc will handle 300whp on pump gas..... if you arent stroking it, then there is nothing you can do with bolt ons to require upgraded injectors... you wont get much above the 300whp mark with full bolt ons, cams, port/polish, full exhaust, int mani upgrade, lightweight pulley/flywheel/driveshaft.... now if you plan on adding NO2, that is a different story... then you would need upgraded injectors with a fully built n/a motor
