+5 HP due to slightly higher compression ratio.
The 5 hp increase in 99 was due to more agressive extrude honing.
For 2000, the engine bore was decreased slightly bringing the engine displacement down slightly (from about 2.54L to just barly under the european standard of 2.5L for tax purposes). With the decrease in displacement, the compression was bumped from 10.00:1 to 10.25:1 to compensate. Even though this is considered a 2000 event, some late 99 engines were already configured this way.
Also, E1 (for 1st evolution) was a Ford term to describe the 98.5 model. E0 is a CEG coined term meaning that it came before the E1.
