which RRFPR rate i must use for my first set-up

i will use the 300zx turbo with stock injectors

no more than 8 psi

really i will start with 6 psi

i dont want it to be lean or too rich

adding a Walbro 255LPH fuel pump can help lower the rate of the regulator ?

with the pump will it be too rich when not under boost ?

since it is a small turbo

i was thincking it wont move a big amount of air so no need for big amount of fuel

thats why think upgrading the injectors aint necesary by the moment

give me your opinions and knowlege

thanks


BTW the car is a DAEWOO Nubira with a 2.2L engine swap
