The CR190 is relatively drop-in. Would need a clutch, downpipe, and tuning to be called a kit IMO. The oil feed and return lines bolt right up. Just needs the GTD intake accordion and compressor outlet damper. Even fits with DPF intact, though I've not heard of anyone running one that way. My whole reasoning behind doing something else was hearing that the CR190 is prone to boost creep. As it turns out, the GTD1752vrk is very boost happy on this motor as well. Would love to see boost logs of a CR190 to compare and see the differences or similarities.
