89 2.5L erg to non-egr intake manifold swap?

Is it doable? I know on the RENIX to HO it is a lot harder, but what about the 2.5L? It looks like the Dorman exhaust manifold and head are compatible across both, but the intake manifold is the biggest difference. How interchangeable are the throttle body's?

Bah, just noticed that the older 2.5 is TBI, not MPFI like the newer non-egr motor.....
