Opinions on new Cobalt

[JITB]

any pics of it yet?

tbw this was like the worst kept secret...lol alot of people saod they would ask abotu the new cobalt SS, and Gm never said waht was gonna be in it, but everyone knew it was gonna be turbo, especially after they release the HHR SS with the same turbo ecotec.


i would sway aittle toward the ms3, but as far as price the ss will probrably be beat it in taht category... i wont admit it being better yet...

The pictures I saw were basically your same styled cobalt. It didn't have the SS kit which would make it more un-noticable but it seemed to be a generic GM cobalt picture with professionally photoshopped 18" rims. And I also suspected the turbo to come out after the HHr SS debuted!

Mine went 14.0@100 stock with a 2.1 60


Add seven pounds of boost (16 vs 23 psi) a good free flowing exhaust, high flow cat/downpipe, custom intake, a $$ intercooler, hard pipes, drag radials, and tuning. Hoping for 12.x @ 106+

Would the Ecu compensate for the increase or would you have to depend on the tuning software of HPTuners (which have made it possible to fully tune and datatlog the 2.2 ln2 motor, Ecotec 2.2 N/a and S/C, and soon to be 2.4 through the Obd-2 port under the dash)?

Also have you found out if you're basically stuck with that turbo or is it swappable directly or even through a possible flange cut to mate onto a different turbo such as the 20G or Gt35r

It's all tuned through the ECU, there is no boost controller on my car. I use HPTuners, the car has a (factory) 5 wire wideband. It really is too damn easy to tune. The turbo is a borg-warner K04 (t3/t4 flange). I want a gt 3071r, but the ecu isnt completely unlocked yet. Still waiting on 100% functionality to add a big turbo. The limits of the fuel system arent known, either. GM rates the entire system at 160lph/7000rpm but its unknown if thats the limit of the electrical pump, the mechanical pump, or the injectors. My guess is a combination of the electrical and mechanical pump. The injectors in theory can handle close to 1000hp. The mech pump, however, cant supply that fuel. Will need a new camshaft ground with an extra lobe to turn the pump faster much past 400whp I'll bet.

The car runs between 13:1 and 13.5:1 (factory commanded 13.2:1 WOT) wot to give n idea of how lean the direct injection runs compares to a conventional engine.

Ahh the same turbo as the Audi S4's, which I've personally seen spool to 24psi consistently for months until some fins tore off some how. Thnx for the info, exactly what I wanted to hear.
