DI possible?
I see the newer 2.4s are direct injected, from wiki: LAF
The LAF is a direct injected 2.4 L. It uses technology based on GM’s other four-cylinder direct injection applications, but with unique features designed for its specific application. This includes an 11.4:1 compression ratio that helps build power, slightly dished pistons that increase combustion efficiency and injectors with an application-specific flow rate.
So new pistons, injectors, what else would one need to make a DI Cobalt? Just a thought exercise for now, awfully quiet in here
I may start scrounging around if this proves doable, I wonder if stock compression would work well enough with DI? Save having to change pistons.
DI+ZZPs supercharger kit, oh yes.
