ive gotten alot of my info from the cobalt guys. heard there can be some clearance issues with the auto but we shall see when we get there. so far i have the LSJ throttle body, intercooler pump, IC pump and intake manifold bracket, some of the bolts that are hard to find and i am working on the belt tensioner. and i hate to keep you guys in suspense but i will probably be collecting parts into next year but i will try to do a detailed how to along the way.

Hey, congrats on going ahead with this!! :thumb:

While the HHR shares a lot with the Cobalt, what you will run into problem wise is that in front of the motor the HHR is narrower and has less depth. That makes the intake a real challenge. PM me and I'll give you sources to make a good intake and how to route it.

I PM'd you about an extra part I have for dealing with the belt and tensioner issue.

Good luck and hope to hear from you soon!

I am interested in this as well... is there a parts list somewhere?

I hang with a big Cobalt SS club, just traded my 06 SS/SC on a HHR... so I am very familliar with the setup. Also I believe we have a spare M62 laying around somewhere.

Am I correct in assuming that it is mostly a matter of putting on the LSJ intake manifold and blower, along with the intercooler pump, some kind of front-mount, 42 or 60lb injectors, and a proper tune?

The Cobalt "published" parts lists miss on many points on the details. :confused:

That and a number of other things! Wiring, sensors, intake, etc. Not as simple as it sounds. :lol: :smile: :eek: :D

its extremely complicated, the cobalt lists always say they are complete but all of them have different stuff. hey raineman if you are looking to sell that m62 PM me its still on my to do list.

well i have the LSJ tb, a few custom intake bolts and the ic pump and bracket for the ic pump.

raineman i may be interested in said spare m62 if its for sale
