Everything will fit.  I would try to use the oil cooler for the 2.1 though.
The longer stroke makes the oil in these engines very hot.  Even with the
cooler, temps of 270 plus are reached at 4000 rpm.  If you are using the 1.9
cooling system, some plumbing changes will be needed to provide water for
the cooler.  If you use the cooler and the early exhaust, you will also need
to use a shorter oil filter.
