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.
And in those answers you will find the Horse Power that gives you the edge over any other XFire you come across. We use to call those cars "Sleepers"... hooah.
*just a small note: Back in the days of big blocks and huge hp we never worried about forced induction (by way of Turbos) but we were all over superchargers. Still the majority of us kids could only afford "Ram Air", the faster you drove the more air was rammed down you carb, we would force feed our engines fresh air by way of open-hood scoops, I think the Crossfire would look very fast with a well designed scoop, or it could look out of date... But for you people looking for a cheap way, (or maybe not so cheap), this is an idea.
