HHR SS injector size
I want to increase fuel. What is stock Injector # on the 2.0 Turbo and what is the next best step up without going overboard ? I have up pipe, down pipe, 9" filter, TrifectaTune, no Cats, and Stage 1 Cams soon to be installed.

You can contact ZZP https://zzperformance.com/ and talk to them.
There are a couple of different ways to increase the fueling. They (ZZP) offer larger Opel injectors but you may run out of HI pressure pump volume in which case ZZP also offers a cam with a larger HP pump lobe to provide additional fuel volume, Another way is to add a 5th injector to the intake manifold which will serve two purposes, One provide the added fuel for power added, two it helps keep the intake tract and valves from coking up. The case of that is the PCV system used on the LNF.
