bigger injectors?

[Frecine]

I started my big turbo build and have been doing as much research as I can, but I can't find out if bigger injectors are a must? I know injector seals are a must which I already purchased but can find anything on larger injectors. Also my build as of now is ATP gt2871r, ATP turbo inlet, Cobb AP, injector seals, 3inch catless DP, with next three mods being larger injectors if needed, hpfp, and bov, followed by a tune. What do you guys think?

there arent any bigger injectors yet...and they shouldnt be necessary with the power levels you are going to get with at gt28, you definitely should get an upgraded fuel pump before you go live on the bt though. bpv probablyl wont be necessary, and the tune should be easy to get through some people on the board.

gt28 isn't a big turbo.

go with a gtx3071

so is your AP installed? or just bought it and want to just put a BT on? you are either a TROLL, an idiot, or so F*CKING new to this platform you dont know any better.

im sorry my response wasnt clear or i dont understand you fully. is your ap installed already or did you just buy it? my point was, if you dont have an AP already installed and you are trying to go BT, you should check out that link i posted. if you already have that AP installed and you are just choosing to go BT thats completely different story all together. so which is it?

I'm not quite sure where your going with this? Everything I've listed is already on the car besides the turbo ,the injector seals and the turbo inlet.

Just swap out the DI injectors for a set of DSM injectors. Might have to use some shims and use some duct tape... but should work.

2871 isn't going to outflow the stock injectors.

I DD a gtx3076r and it's fine, so ain't nobody gonna tell me 3071 is too big to DD.

The OP didn't saying anything about this, but I feel I should add that a 2871 won't outflow the stock injectors if running on pump gas. You will run out if trying high E85 mixes.

To answer your question simply....no they are not a must, but get a new fuel pump...also your stock pump is a hpfp, just for future reference.

Anyone knw where I can find the tune for ap specified for my turbo and mods other than getting it pro tuned!

Im guessing you want something for nothing when you are only 5 posts deep?

[Frecine]

I'm am willing to pay I have been looking for a preformance shop in the local area where I live and I can't find one that is familiar with the speed3 just tryna get an actual tune and If I can get it online why not....but would I be able to download the pro turn straight to the ap ?!

[Chimmike]

You have zero familiarity with this car, so I'm gonna say, get it protuned by someone who can be hands on and can see if you've installed shit correctly or not.

Also, having zero familiarity will not assist you in e-tuning with someone.

Imminent fail detected.

[captain slow]

Dude, sounds like you took a big leap. PERM tuning is pretty sweet and can pro tune you but they can only help you if your hardware is installed right and working properly, which it prolly isn't. You need internals stat!
