Does anyone have the answer to this? What is the weakest link, the fuel pump? Injectors? Seems like the injectors would support about 250 wheel. How about the size of the fuel line?

Thks for any feedback.

I searched but couldn't find an answer.

 

Just to clarify, I have the S14 sr20det, so the pump and line is from the 97 240SX, and stock injectors for that motor.

 

fuel pump needs to be changed by like 8psi, it is the absolute weaksauce, then the injectors at around 250hp (14psi on stock turbo)..maf after 300hp

 

Thanks.
