I'm going to start a thread on my journey seeking the all powerful Boost. I have nearly every part of the turbo system ready to install. This does not include all of the supporting mods that will eventually be added, just what is actually necessary to add a little bit of pressure to the intake manifold. It will be a two stage project. Stage one is minimal positive pressure (5-6psi) on a stock 2010 LS. Stage two will be full on insane, Garrett GTX28, 60lb injectors, rods, pistons etc. I have a parts list if anyone is interested.
I've sourced everything so far for less than $250. Almost everything will come off the Saab 9-3 for the first generation of this project.
2005 Saab 9-3 exhaust manifold, Garrett oil and water cooled turbo, oil and water lines were all removed from a junkyard 9-3 at a cost of $130.
2009 cobalt SS turbo intake manifold: $55 on eBay. The turbo throttle does not have the same wire plug as the base, but the base throttle bolts up to the manifold so I will run my throttle on the SS intake. Note that I have gained a lot of info from the Polaris Slingshot forums. Those Slingshots come with stock 2.4 ecotec engines and there are guys running up to 9 psi on the base plastic intake manifold.
The oil lines are easy, I'm going to do it just like stock, the feed comes off the balance shaft passage and there's a small depression just above the oil pan which can be drilled and tapped for a gravity return.
The instructions for the Hahn Ecotec turbo kit are floating around and were helpful, I'll try and post a link here when I find them again.
