I have a lower intake manifold, supercharger, and snout assembly from the Cobalt SS / Saturn Ion Redline LSJ Ecotec engine. It's an Eaton M62 blower which is a roots-style with coated helix-style rotors and rear entry/bottom exit. The setup is complete with boost diaphragm, vacuum-actuated bypass, and MAP sensor. It is further upgraded with a GM LS4 throttle body, a ZZP modular pulley system with a 2.7" pulley, and a ZZP dual-pass intercooler setup. This can bolt onto and run on any Ecotec motor (2.0, 2.2, and 2.4) and can even be run on a factory GM tune.
You would need to source injectors, a longer belt, the tune, and a heat exchanger.
Super-duper GRM-only fire sale price of $550 plus shipping (and it's big and heavy). The ZZP parts are over $200 new and a stock blower/intake setup goes for $750 on eBay all day long. I underpaid for it in the first place and desperately need some money since I wrecked the Ecotec car I had...
