Going even bigger on the turbo. Share your thoughts
Has anyone ever fabbed up a TT setup for a cobalt? It would be pretty neat to run two K04s or something even a little smaller. I know there isn't **** for room in the engine bay as it is but I've seen some top mounted turbos where the wheels are sitting outside of the hood out of a cutout.

OP, stop being a ***** and just mount this bad boy up. ^.^

the only way i could see doing twins. they would have to be terribly small. so small that even with both of them, peak power just wouldn't be there. one mounted on the manifold to get most of its spool from cylinders 1 and 2. and the other mounted by the tstat housing getting most of its spool from 3 and 4. compressor housings on the timing chain and trans sides respectively. with the turbine sides in the middle with a shared downpipe connected in a way to prevent the exhaust coming out and flowing directly at the other turbine housing.
and even IF you could get that to work. a single 252 or 256 will still give you a crazy power band with the peak to go with it. in a simple bolt on kit with none of the custom fab work, other than modifying something to your liking, that would come with a twin setup

the s262 actually comes in a .55 ar as well. Should spool much quicker than the .70 exsoccer is talking about.

Eww that spool on the s262 is not pleasing. Before the S256et i was actually looking at doing a custom manifold and a EFR7670 in the first place, i could just never get a hold of one. As silverbullet stated, there will be something in the works soon 
Thanks for the info everyone. I will also be looking at some suspension/tire mods to actually put this power down.

none of us are running a divided housing though. all that does is put a space between the manifold and the turbine housing and directs the exhaust flow to one portion of the wheel vs having both parts of the manifold on the turbo. and then opens up when its time to make peak power.

kind of defeats the purpose of having a divided manifold because the whole point of one is to separate the exhaust pulses and have every combustion alternate between left and right openings so they're working with each other instead of against like on a log style. even running this on a log style the exhaust pulses are still working against eachother. i haven't heard of anyone running one of these on a T3 or T25(would be even less effective). but i can imagine them not being worth it..
just my two cents.
actually, now looking at the picture compared to yours, it doesn't redirect it. it just blocks that side of the manifold all together.

All the exhaust energy is routed through half the turbine housing
