I know the 06-07 cobalt or Saturn sky if the forged gen II block to get for boost. Are they pretty much a straight swap? I know DDM sells their motor for 5k...but looks like a cobalt or sky engine can be had for a lot less.
DDM uses the LEA block from the Equinox or Traverse The major difference is the block is Sand Cast not foam cast and much beefier that the LE. The swap is relatively straight forward except if you are boosted. There are no ports on the left side to get oil to the turbo - some creative plumbing is involved. But I have to agree go with the DDM build it is a solid motor
