Halfcents 2005 Turbo Coupe
*Edited 2/21/06. See new pics lower in the thread!
Hi everyone. I'm starting this thread a little early to get a head start on it. I'll keep it up to date as best I can. As many of you know, I'm building a turbo charged automatic Cobalt. Here she is...
My goal with the car is have a %100 street and emissions legal car producing the most power possible within that limitation with an automatic trans.
Well, it looks like I'm back on track after many set backs, first engine getting destroyed being one of them.
I spoke with Ferrea today (supplier of my valve train) and they should have my package shipped to me by Friday (2/17). Car will be back together probably the next day. I wanted to give all of you a complete list of what I have done so far, and what is to shortly come.
As you can see, I have the RK Sport body kit which was done professionally for about $600 painted and installed. I had the rear 3 windows tinted %20. Then I sent it in for the major engine work which is where I am now.
I had my Transmission done by IPT transmission. This was probably the most important part. IPT rebuilt the trans to handle just about anything you can throw at it. IPT gave me a 3000 RPM stall converter as part of the package for the turbo. Then I had a LSD installed which i got from Engineered Performance. IPT is making a custom controller for me that will allow me to dial in firmer shifting for performance driving and smooth shifting for daily commuting. In cabin, on the fly adjustability.
The engine has had the rotating assembly rebuilt using the stock crank, Eagle rods, and Wiseco reduced compression pistons. That was the easy part actually.
The head was the reason my first engine was destroyed. We used the Bates Engineering valve springs that are described in the Ecotec build book. They were supposed to allow us to spin the engine 1000 RPM faster. Well, one failed right away and caused a valve to drop.
In my quest to replace the head, I learned about the difference in cylinder head castings between the 2004 and 2005 model year of the Ecotec engine. See my thread on that one here. Thanks to Maven for the lesson there.
So I had to buy a brand new head (expensive, ouchy) and this time I went with a Ferrea valve train. I don't have it yet, but I already feel better about it. This time I have replaced the entire valve train, not just the springs. And the springs are dual coil, so if one breaks, the other will prevent a valve drop. This set up will allow a new red line of 8000 RPM.
I intend to break the engine in normally aspirated for a short time. Then it goes to Hahn Racecraft for the installation of the turbo. I haven't been releasing this email for a while because I couldn't be sure it was going to happen until now. So here's Bill Hahns note:
Geoff,
The package as described here is capable of 475 HP on 110 octane fuel, but will be usable on the street at an approximate power level of 325 HP on 93 octane. Splitting the difference with, for instance, 100 octane unleaded is also an option. We would set up the different boost/power levels to accomodate your preferred fuel option(s).
An item not addressed below is the catalytic converter. This can be upgraded (the stock piece will not be appropriate) to suit your particular needs insofar as emissions preference and testing requirements for your region.
Our accomodation to you would be the complete installation, and resultant tuning work, at no charge. This is an approximate savings of several thousand dollars overall. We would expect to recoup our investment via the developmental information gathered during the process, as well as in the attention this car will then achieve as it demonstrates itself to the public via enthusiast internet boards, race/show events, and magazine coverage. I'd like to also see what your plan is in this regard as far as getting the car exposed.
====================
Intercooled Cobalt Turbosystem with following upgrades:
Super 20G Turbo
Turbonetics Raptor blow-off valve
StreetRace Sheetmetal intake manifold
PortFueler fuel enrichment system
Profec B electronic boost control system with steering-wheel mounted remote control
3" stainless steel cat-back exhaust system
Please let me know what you think,
Bill Hahn Jr.
Anyway, I have additional plans as well for suspension work in the coming year. Electronics after that. Still putting together what I want to do there. Right now I'm trying to figure out what I'm going to use as a Front Wheel Drive Drag Radial tire to use at the strip when off-street.

god dman boy!!!!!!!!!!!! 
I like the concept bro! good thing you upped the tranny cus 300 hp WOT one time prob would kill it! i would say you sould hit 12's easy (autos easier to launch) youll def need a drag tire cuz you are never going to grab the ground

Wow, I see all the things you did/spent on the 2.2L.
I'm starting to get rough figures for my NA all motor 2.2, keep up the good work.

Halfcent, I have admired this project ever since I heard of it a couple months ago. I can't wait to see it finished. Good luck in this time consuming project!

Engine is done!
Here are some pics of the engine just before we reinstalled the head. Car will be on the road tomorrow.
Here is the timing end of the short block all put back together and ready.
Here is the top of the block. You can see the brand new replacement Wiseco piston there. The other 3 were fine and were reused. Notice the nice concave "dish" shape for forced induction use.
Lastly, and most expensively, the brand new head with the Ferrea valve train. No EGR casting. Dual coil valve springs (hard to see I realize), titanium retainers, triple groove valve stems and locks, stock cams.

It really isn't about how much money you spend but what the final product is. Halfcent could have spent even more but all that matters is that there is no other cobalt like his.
