Anyone know what the difference is and which you would rather use if you had the choice of the 2?

the early one has better pistons, a lighter crank, more of them had coscast heads and some of them are pre emissions

I see, so the 20xe is a better engine for a track car?
Mine is a 20xe coil pack type though?

Difference in power was due to the early having no cat converter, and late having a cat converter.
Non are better than the other, both have advantages over each other. On paper, the early engines look to be better spec'd, but ive heard of more people preferring the later coil pack engines over the early dizzy engines.
20xe coilpack engine would need to be a mix and match of both. 20xe bottom end with c20xe head.
On the road, with 2 healthy motors, you wouldn't notice any difference.
Also, coscast head weren't fitted to all early engines either. Was alot of mix and match, and even some coilpack engines got a coscast head.
