Does anyone know when the Hahn 2.2 Turbo kit is coming out? My brother wants to buy one and i'm trying to find out more info on it. Aren't there stage kits as well? He keeps talking about getting the Hahn Stage 2 kit. I keep telling him that it isn't out yet but he doesn't belive me.

Might not be out yet, but Hahn does use a stage system. Heres what the lineup looks like for the J-body kits:

Hahn kits, and any others for that matter, for the 2.2L Cobalts are being held up due to a lack of fuel control options. They are all waiting for a software solution to the model E16 ECM in our car. HP Tuners is working on it.

No kits at all have yet been released. Your friend may be confusing other Ecotec turbo kits with this one. There are other Hahn ecotec kits in retail market, just not for the Cobalt yet.

The Hahn 2.2L Ecotec kit for Cobalts will be released AFTER the 2.0L and 2.4L kits, which should be early fall or so. Expect the HRC kit to take 3-4 months after that.

the latest news on it that i have heard is it will be released before spring of 2007......ie: early next year......soooo.....this is good for us poor guys who need to save up.....well...not poor but not f*cking rich......

... isn't the 2,2 the same as the 2,4? wouldn't a kit for one fit both?

Also, why wouldn't a kit from a last gen J-body work on a 2,2 or 2,4 balt?
sorry, newbie questions, not used to forced induction, didnt need it on my old car

More than likely it's all about routing piping.

Also, the J-body and Cobalts have 2 different engine bays.

tell him if hes really tired of waiting to get a f.a.s.t xfi and have a custom turbo setup. unless the computers wont let you use that either

No previous kit will work on the Cobalt. Yes, it has the same engine as many other cars. All the hard parts of the turbo kit itself are the same. However, the 2.2L Cobalt is using a completely unique ECM. Each Cobalt model, meaning the 2.0, the 2.2, and the 2.4, all use different computers. The 2.0 and 2.4 have been successfully cracked and support is now available for those. The 2.2 has not yet been cracked.

Historically you could use a stand alone fuel control unit and not mess with the ECM. You can still do that, but you have no control over ignition, and the ECM gets really screwed up when it sees the engine performing in ways it has no data for. You can't just bypass the ECM either in the Cobalt. The ECM supplies data to the power steering and instrument cluster. Both would become inoperative.

Yeah I told him it wasn't out yet because there is no program out there yet to modify the 2.2 computer yet. He then asked me if he should get a custom one done. I told him the same thing, that he would need access to the computer which no one had as of now. He has the money though for stage 2 plus installation..well he should anyway. The stage 2 kit can't be more than $3500.

I also told him he would need a new clutch as well. He told me since he wouldn't have much more money left over, that he would granny shift it....Floor it in every gear, but granny shift (which is what I have been doing for the past 3-4 months while shifting at 5500 rpm and still winning races lol)

so basically, I could get a j-body kit, modify the piping a little, and then get someone to crack the computer?

Halfcent

OR!!! You could wait to buy a Cobalt kit, end up spending less money because you didn't have to modify anything, and not have to wait around for somebody to crack your ECM because that's what you will end up having to do since that's what everybody else is being held up by.

Ok my bro is now changing his mind...oh btw, he is my brother, blood related, i don't call my friends bros lol. Anyway, he wants to do what your doing now halfcent. With all the internal custom crap, new block, yadda yadda yadda...I told him not to because he doesn't know very much about how engines work, he knows what parts do but he wouldn't know how to tune it or anything. I told him to wait for the turbo kit to come out.

Well, when a kit comes out for the cobalt around how much should I be expectin to pay and where can I get one at..?

Skottish

you will be able to get it from the website i believe hahnracecraft.com ........from what ive heard it will be under $4000.......also, the 2.4 kit will not work on the 2.2 due to a difference in manifold size and difference in the pcm......

IonNinja

why couldn't we use what the LSJ guys were using before HP Tuners was released?

a MiniAFC and MAF-T?

memphisr24

Yeah my brother asked me if he could have my MAF T when I get a custom tune, but I told him it may not work properly....I have to ask Intense racing about that.
