i have a greddy kit,adaptronic ecu im going to be going from 6 psi to 12 how big of injectors do i need?ive been searching posts on here but havent found much

 

Injector sizing is based on horsepower, not boost pressure. Boost pressure isn't directly related to horsepower. What horsepower are you going to be at?

 

12 psi on the greddy kit? that turbo would have a hard time and get a retirement really fast..lol...
RIPWW is right, what are u aiming? if you still have stock greddy, you better not exceeding 10 psi...enjoy the base psi, which 6 psi, but most of ppl are running between 7-8psi, and that is a blast with greddy...trust me, once you change the injectors, you have to change the pump...good luck,...

With the stock Greddy turbo you don't need anymore than stock injectors because the turbo can't flow enough air .

 

Oh but I am sure if he is dealing with Turdblown, they are trying to sell him some Injector Dynamics injectors (good BTW, IMO).

OP, you need to do your homework man, there are many threads discussing this stuff. If you don't want to get screwed out of anymore money I suggest you buckle down and start reading.

 

if you are planning on running this engine on 12psi of boost--you dont need new injectors--you need a built engine....this engine is different.
just trying to save you some h/a's/money.
