This kit from Fleece Performance Engineering is referred as a “2nd Gen Swap” because of the turbo relocating from the back of the manifold to the same location as the second generation Dodge turbo location. In other words, the swap kit locates the turbo in the center of the manifold with the outlet flange angled down. The major benefit for 2003 and newer Common Rail Cummins trucks is the use of a divided manifold. Capitalizing on the individual cylinder impulses in a divided manifold greatly increases spool-up and driving characteristics with a properly matched turbo. (317-286-3573/www.fleeceperformance.com)
