Does anyone know about or has actually installed this on their Cobalt. I was looking at getting one for my 2.2L. There is a Stage 1 kit that gives you 180 whp. I will probably have to do some engine modifications if I put it on. Does anyone have any info on it?

 

use the search button there is like 5,000 tubro threads
and a few people have installed turbos

 

i thought the kit wasn't out yet? fuel management issues...

 

There is NO turbo kit for the Cobalts yet. The 2.2 kit is for Cavalier and Sunfire.

 

Please, PLEASE do use the search feature first before posting. There are no turbo kits out yet for ANY Cobalt. Yet....

 

Halfcent will you sticky some stuff for the 2.2 area i.e., Intake, Exhaust, Turbo/Lack thereof, etc. I think that will clear this area up as most of the posts are for those 3 things.

 

i have a question about the ecu issue. would the ecu for a ecotec cavy connect to our wiring harness? if so couldnt we just use that ecu....

 

It doesn't matter if it would fit. It is a computer telling different systems what to do and if your systems don't get the proper message, nothing works.

 

So what exactly would the ECU change when a turbo is added? I thought just fuel and ignition would be adjusted. Just curious because I don't quite understand the difference between 75hp added from NOS and lets say 50hp added from a turbo system.

 

with nitrous fuel is added with the nitrous normally unless you buy a dry kit which can be bad but also the nitrous doesnt pressurize the cyl like aturb would along with you need diff timing with nitrous compared to turbo etc

 

This is a good idea. I'll try to work on that this week.

You can't use a different ECM. The Cobalts ECM provides data to other vehicle systems (like the power steering and the instrument cluster) that would not work if you swapped it out.
