Hey Guys

Im considering upgrading my current charger to the ET 137 + 4 mm spacer from the store.

Im currently running the Riva Pro Series wheel and housing which i purchased a couple of years ago. My question is, do i need to install the original front housing from my stock charger (255) with this new wheel and spacer or can i use the one that came with the Pro Series wheel.

Im also using the Pro Series 50`s injectors (delphi`s i think) as im also running the Riva Pro Series ecu.....see mods in my sig.

Will i also need to change to different injectors if i upgrade to this new wheel and spacer....I do monitor afr`s and run slightly rich with the mods i currently have installed.

Any advice greatly appreciated guys.
