I'll be installing the 5th injector kit on my 2010 Cobalt SS/TC soon, as part of my turbo-swap (ZFR). In fact, the tracking tells me I should have it on Monday. I plan to install the 5th injector kit myself, then bring it to a shop for the turbo and clutch install. I'll post a link here to the how-to I plan to make and post on my club's forum 5280cobalts dot com. My HP goal is 450 on E85.

 

Im scared of meth. A few cobalts i know run it, and they have no complaints but its just something I personally dont like. Although I might have to get over my fear If i cam and 5th inj it.

As far as tires, i know its gonna be hard but i shall figure that out. I want to run 295 but they will poke out. Worst case just swap em when im goin to the track.
