Injector question

[gti_7]

HI all

i have a friend, who runs a 2.2 TII. he wants to know how [if?] he can run +40 injectors and a big fuel pump on the stock calibration.
and if he can. how to do it. he wants to run 18psi as a daily.

thanks

Yes he can. To get the 52lph injectors to run smoothly for daily driving, you will need to lower the base fuel psi from the stock 55psi to around 30psi. But now, the 52lph injectors are running like 38lph injectors, only a marginal increase over stock. So, if you want/need those 52lph injectors to flow as they are meant to, you will need to get a Cartech RRR to raise the fuel psi back up to where it should be under boost.
