Ok so im looking into getting this setup and ive been talkin to the guys at hahn, who been very helpful btw, and they recommend that i get mounts for the trans and motor and eventually a clutch. Is there a company that you would recommend? Also, would the stock suspension and brakes be able to handle the type of hp this set can produce? Thanks for the info.

i was the test car for the hahn kit and i put in a clutchmaster stage 4 and lightwieght flywheel. stock suspention is great for it!

Chief

What flywheel did you use?

sleepercobaltsc

clutchmaster light weight

Chief

what other mods did you do after the install?

sleepercobaltsc

just poly trans mounts and control arm bushing. stock everything else! i would really recommend getting the greddy profec 2 with the kit. it will help ur launch a lot!

Chief

im also considering their cat-back, headers and downpipe. Would i need to add/cahnge anything else if i get there? what kind of numbers are u running? ie hp.

sleepercobaltsc

Their exhaust bolts right up, at 15 psi, i am making 320 horses and at 18 psi i am making 360 horses and 343 torque. the dynos are on hahns website

I wouldn't go with the CM flywheel. Get the Fidanza and save $100. Thats what I did and its fine.

you cant get a header with a turbo set up. you'll need a turbo manifold. also what style cobalt do you have? 2.4/2.2 or 2.0?

Chief

i have a 2.0. i plan to get the whole turbo swap so wouldnt that take care of the headers? on a side note, i hate to sound like a noob but tmfw? i dont know what that abriviates... any suggestions on a clutch? i wanna make sure i have all my bases covered so anything that i might be missing out on please let me know. i'd hate to spend the cash and forget something and ruin the whole thing :/ thanks.

The hahn kit takes care of the header and i the down pipe. hahns cart back will bolt right up with that

you prbly just need the catback, new clutch/flywheel, and poly trans mount bushings, ive heard loots of good things about the exedy clutch and it somes w/ the flywheel.

so this is the stock motor???????

nm. this is prolly non ss/sc related huh?

sleepercobaltsc

Its the hahn 20g turbo kit for the lsj

Chief

I plan to get the clutch from hahn though it doesnt say anything about a flywheel coming with it. i was looking at the sway bar on www.turbotechracing.com, is this something i should consider getting too? how much do you think labor is going to cost on a job like this?

Chief

so i was checking out the hahn site and they have a couple cobalts pushing over 400 hp. How is this attainable?

Im bringing my car to hahn on july 28th and picking it up august 4th- getting the stage 5 so if you want me to let you know more about it once everythings on id be more than happy to let you know numbers and drivability, etc. I will be on stock clutch and axles but will be very soon afterwards upgrading to the exedy hypersingle and stage 2 axles. One thing is I will be running a high flow cat since NY emissions.

The 400 whp is attainable through the their stage 5 kit- if you dig a little deeper you will find out that some people are running 400+ on stock motor (pistons, rods, valve train) but I will be in the 320-340 range (i hope lol) I just plan on running the 15psi and will eventually get a boost controller down the road (when i get bored haha)
