...the next step will be identifying specific parts that are beneficial to swap between engines. For instance, which has a better intake manifold? Does one have larger diameter MAF than another? Are the ECU calibrations the same? How about the accessory drive, is one lighter than another? Does one have slightly less restrictive exhaust/intake ports than another? Is cam timing/ duration different between them? Does the forced induction motor have a beefier crank? Does one engine have less restrictive exhaust manifolds than another, and is the geometry similar enough to perform a swap? All of these questions beg to be answered.
