Hi guys,

I'm currently running BC 272 cams + walbro 255 at the moment. If I plan to upgrade my turbo to evo9-20g + ETS 3" i/c would I need to upgrade my injectors? I plan to run around 1.5bar max boost.

thank you

 

whats 1.bar in psi? id say if you run over 26psi your gunna be heading towards the stock injectors max...my opinion, i keep my safety margin pretty big

 

1 bar = 14.5psi

 

With ether bigger turbo or bigger cams is generally accepted that bigger injectors are needed.
