HEY GUYS, I'm going to be swaping injectors in my Z from the stockers to some Seimens 60#ers. First off, will these work fine on a stock vehicle? I'm putting a supercharger on as soon as the injectors are in and tuned. What do I need to change on the tune? Do I just adjust the main pulse width voltage table? Anyone have the formula I need to follow?

You will also need to adjust the I.F.R. table. Do a search for an IFR spreadsheet by Marcin.

Thanks for the info, I finally found it. This leads me to a couple other questions. One, my stockers would be 43.5 psi, 26# (2000 Camaro) and my fuel pressure should be 53 psi right? My new injectors are 60# Mototrons. They would be 43.5 psi, 60# with the fuel pressure at 53 psi correct? Just making sure I don't put any bogus numbers in a pop my motor. Thanks for the help.

the stock fuel pressure is 4 bar 58psi, the stock injectors in a 2000 flow 26 only at 58psi fp. The new ones are rated 61 at 43.5. In your car they will flow approx 72lb/hr at 58psi. So, set your IFR accordingly

That's what I thought but seems like everything else is three bar. Thanks for the info.

Why are you putting those in the Z?

Yes, I think the G8 has 42# injectors from the factory so it should be good for a while. I just supercharged the Z so it needs to bigger squirters fast.
