Joe is right. The new Turbo LNF motor has the VVT on it. A VVT or VTEC system actually HELPS the turbo by giving better flow to help spool the turbo and bottom end when the turbo is spooling. The "moving" cam will also allow for better and possibly longer openings to allow more of that sweet boosted air into the combustion chamber as well.


The reason this kit is not available for the HHR yet is because the piping would be different for the intercooler. We have a completely different engine bay arrangement and routing choices than a Cobalt has. So this kit COULD work as long as you dont mind fabbing your own piping. Just takes some creativity. Other than that the turbo, manifold, tuning hardware and everything else BESIDES the piping WILL work. The HHR is JUST A Cobalt wagon.

 

Hi, I am new to this forum but I have been reading it for a long time. I own an 07 HHR Fall Edition and also own an 07 GXP Solstice. My GXP in currently at Hahn Racecraft. They are using it as there test mule. I left my HHR with them for a week so they could evaulate it to see if there Colbat kit would fit. Bill Hahn said the only part of the Colbat kit that would work was the exhaust manifold and the turbo. The tuning would be the same, but all the plumbing and intercooler would have to be made for the HHR. I now if they receive enough interest in a kit for the HHR they will build it. I drove there Colbat that has there Turbo/intercooler Stage 2 kit on it and all I can say is I want one on my HHR. It will fry the tires when the turbo comes in. Here is a link to there web site, http://www.*************.com/ they build some really awesome turbo cars. On there home page, click on the (Take a Hahn RaceShop Tour w/ V8 TV) and see what they can do for a Mustang. When they were outside filming the Mustang the HHR in the back ground is mine. If any of you guys are interested in a turbo kit for our HHR's, PLEASE email them and say BUILD US A KIT. I know you will love the power. It is amazeing the power that the 2.4 will make.

 

to the site turbo wanabe!!!

 

Thsi company is WAY more respected then the other claiming the turbo kit....People who know about them should know there in it to win it. Simply put they were working on the turbo for at least a year and a half but wouldn't release ANY info because they wanted it to be reliable before they did........Now with the SS coming for sure there will be many "performance" appearance packages for us i.e. hood, other body kits, etc.........

 

Tell Mr. Hahn that I want one! I've been waiting almost two years now! If he can build 'em for PT Losers, he can make 'em for us too!

 

I`ve been checking back and forth on this thread, with interest, and I know that Hahn has a good reputation, but it appears they`re just testing the water and throwing out feelers.
I think a better option would be to just transplant an entire 2.0l turbo powerplant into the HHR and work the suspension.
What`s the expectation of hp with a turbo on a 2.4l anyway... will it be more than the 260hp in the 2.0l, and what about the internals, there`s a lot of parts that would need to be strenghthened to be reliable not to mention the warranty issues.

 

Here is a page from Hahn's web site on the Colbalt kit. Check it out. http://www.*************.com/New_Fol...20Solution.pdf

 

Looks like a good external set-up, and the hp is impressive, for about $5,000.00 parts.
No internal parts on the page..., rods, pistons, gaskets, injectors, you know the other little things. Looks like they focused on intercooling.

 

Hahn's had the 2.4 engine reliable up to 450 HP with no internal mods. 290 is nothing for the stock Ecotec internals at the insanely LOW boost settings from the Garrett turbo. The only reason why they're capping the boost is to make it run on pump gas and not destroy the 4T45-E transmission. Of course, if Archie can run a 400 HP small block on an ancient 2T40 transmission in a Fiero, I think our automagic could handle a little more power :)

Injectors--Hahn uses their own "add-on" injection system that adds four more injectors at the port between the head and intake manifold. That way they can just add a piggyback computer and not have to screw around as much with the stock PCM. Pretty seamless setup--a lot better than when the Honda guys would throw a Mitsu turbo on a B16 VTEC and put a fifth injector on the CAI tube to keep it from blowing up!

290 HP does beat the 260 on the 2.0 DI Turbo, but the final gearing, power-to-weight, and PCM program will make all the difference on the track.

 

Wow your lost, hanh has been working on this kit for 2 years, their stock cobalt 2.4L hit 290hp and ran 13.7 at what was it 8-9psi? you can easily push it to 10 and hit 300hp, The ecotec build book says are internals are good for 350 (correct me if i'm wrong) Also the they have one in the rwd 2.4L and pushed upwards of 400hp..........Piston, rods..wtf? if you want your engine re-worked to handle 400-500hp with out a thought other wise you shouldn't have got the HHR in the first place. This kit is intented to add some hp not make your car a f'n corvette.
