[[File:2006 Saturn Ion Red Line engine.jpg|right|thumb|250px|Ecotec LSJ engine in a 2006 [[Saturn Ion|Saturn Ion Red Line]]]]

The '''LSJ''' is a supercharged version of the LK9 Ecotec {{cvt|1998|cc|L|1|order=flip}} with an [[Eaton Corporation|Eaton]] M62 [[Roots-type supercharger]] and air-to-liquid [[intercooler]]. The LSJ shares many of its components with the LK9 such as: piston cooling jets, oil cooler, pistons, connecting rods, crankshaft, oil pan, sodium-filled exhaust valves and cylinder head.<ref>{{cite web|url=http://archives.media.gm.com/division/2005_prodinfo/powertrain/index.html|access-date=16 April 2014 |title=Site Maintenance }}</ref> It is rated at {{cvt|205|hp|0}} at 5600&nbsp;rpm and {{cvt|200|lbft|Nm|0}} at 4400&nbsp;rpm with a compression ratio of 9.5:1 and a 6450&nbsp;rpm redline. With the end of the Chevy Cobalt S/C SS and Saturn Ion Red Line, the LSJ was discontinued after 2007. In late 2005 [[Brammo Motorsports]] struck a deal with GM for the [[Supercharged]] 2.0&nbsp;L Ecotec for their [[Ariel Atom]]. The engine came in various ratings from {{cvt|205|hp|0}} to {{cvt|300|hp|0}}.

The LSJ was on the [[Ward's 10 Best Engines]] list for 2006.
