Just stared getting serious about fixing up my 04.  I have been giving it time for the aftermarket to catch up.  Done some searching to no avail and much frustration.  So... who all makes turbos for the 2.2 L ecotech and does everthing come with it in a kit?  Which gives the best performance?  Thanks alot, so far this forum has been bad A !!!
 
so far its seems like the 2 most popular kits are han and hass
