What turbo do you actually have? That description is vague at best.

Your injectors will inhibit you alot.

That's right on with what my T2 flanged GT3071R says... If you look where your lines go, if it's a legit Garrett turbo and someone hasn't removed it, There should be an aluminum id tag with an identification number. I recommend getting that number and try emailing Garrett.

P.S. Your stock fuel system can't push enough for a 3071.. You'll lean out quick.

You really can't purchase the right size injectors without knowing what turbo you have...

My 3071 doesn't APPEAR much bigger than my T25... T25 is fine with 370cc injectors... For my setup, I'm going to be running 810cc injectors... You seriously NEED to figure out what turbo you have so you can get a proper setup. I've told you that all you need to do is look at the id tag and give that number to Garret.

You buy injectors based on your HP desires, not the turbo. Injector requirements on a 3071 @ 14psi is not the same as the 3071r @ 28psi. You can buy whatever injector size you want as long as you can control them. Just buy the biggest size within reason. Doing that will save you from selling your old injectors and having to buy a bigger size when you upgrade. And you will upgrade...you don't have a choice

Noone is going to want to buy a car that you threw a random turbo with some random injectors together... You're basically saying that you're setting a car up to lean out and ruin the motor just so you can sell it...

Yes, you are correct... But I believe I'm pretty dead-on when I say the average person builds their car for 16-20psi of whichever turbo they own.

i am only boosting like 8lbs and i got the turbo as a basically stock turbo when the stock one had bent exhaust fins. i am going to get it tuned and if i need injectors, then i will put them on and retune it

You (should) buy your all components based on your desired hp level. You can buy large injector without detrimental effects.

I hope people don't build their cars because they want to run XX psi with YY turbo.

Eh... You are totally twisting what I'm saying and I think you're doing it unintentionally, so I'm going to clear it up. MOST people, when they buy their turbo, have already planned out that horsepower. You choose your turbo based on which one is going to hit your hp goal with the least lag. (You wouldn't buy a GT35R to make 300hp.) Most setups I've looked at were running around 20psi as their peak boost. (YES, THERE ARE EXCEPTIONS.) Now, this leaves you with whatever injectors you need to run. That horsepower goal was already chosen when you purchased your turbo (MOST OF THE TIME) Unless, you're retarded and buy a random turbo from some shop and don't even know wtf they sold you.

Just because I own an SR, doesn't mean I haven't touched an RB. Besides, his stupidity would be stupidity on a KA, an SR, or even a freaking 4G63. I'm trying to help keep this kid from making an ignorant decision that could cost him, or an unfortunate buyer a lot of money. Sorry if that's a problem.

What I'm saying is to choose the right injector NOW and you won't have to upgrade them LATER.You can run 850cc injectors with a stock turbo if you wanted to. You can then use the same 850cc's run a T66 LATER. I don't know about you but most people almost always upgrade.

I'm not too concerned about it. Either way man... You do understand that 8 pounds on a stock turbo is different from 8 pounds on a 30 series turbo right? I'm not attempting to flame you by any means. I'm just trying to save you, or someone else some serious cash. That shop should know exactly what they sold you, so there's no reason you shouldn't be able to take a few minutes and stop by there shop. "Hey I bought this turbo from you on this date, can you tell me what it is?" Then you would know exactly what you have, and what kind of fuel setup would be your safest to go with, for either mild boost at the moment, or high boost later on.

We're on the same page here, man. That's why I reconfirmed what I was saying.
