120# injectors
Ok so I was wondering has anyone ever tried to use these before in the cobalt ss? http://www.trickflow.com/partdetail....1&autoview=sku
I got a guy with 4 and hes willing to sell them for 200$ for all 4 of them. i might pick them up and see if they work or not.

Yeah I know right if they work I would just need some help with a map for them. I aint too good at doing that. But maybe area will help. If they fit and work I would drop to a 2.5 pulley on e85 and see what I dyno at. I get to take a look at them on sunday and I get to bring one back to my place to test fit it.

Those are low impedance injectors. You can't drive them with the factory computer. You will need to add a conversion box($300). Your next issue will be trying to run a short enough pulse width to idle at stoich. You will need to run a full boost/vaccum reference fuel regulator to bring the pressure down to about 40 at idle and then you might be able to make them work with E85.

i say lean pig cause my car bogged down when it happend and sounded like a grunting pig kinda. Everything is fine till I get to 4th then top of 4rth at 6200 rpm it jumps from 11.7 to 17.1 and the maf is only -2 so it should be that far off. I know I am out of fuel and need more. you think the boost ref will help at all? Also can you make the boost ref a return style fuel system too?
