running completly stock ls. how much psi do you think my stock injectors can handle if any?

57 trim. log mani etc

was only really looking to to run 7lbs?(not quite sure what the motor can take)

 

even the greddy turbo kit thats only a t28 comes with (i think its 440cc) injectors for its kit which is set at 7psi...so i wouldnt boost at all with stock.

 

Stock injectors will not work for a boosted application unless you had a single came 1.5l with prelude 330 injectors.

Dont be cheap just buy injectors and get the car tuned. 450's will get you to around 300hp with the right fuel pump and regulator maybe a little more

Your next question is can the stock fuel pump handle boost and the answer is no more than 7 psi and thats if you leave stock fuel pressure. so yes spend the 100 bucks on the walbro

 

well thank you sir.

 

NONE unless you are looking for a reason to buy a GSR(after you blow it up within the first 10 min)
