The upgrade actually came sometime midyear 02...as my 02 Axiom STILL had the older style valve covers??? Also the updated 03-later engines have a much better PCV valve...My 02 Axiom engine (dealer installed in VX) is great! 230 HP and NO oil. Consumtion at 60K + miles....
If it were me, Id buck up for the 250 horse 04 version...with direct injection....
A little more computer swapin, but well worth it!!! In the future, expect to see folks experamenting with alternitive fuels on this engine, as with DI, the possibilities are enless....much improved gas mileage as well.
And DI engines can handle much more boost, in the event someone wanted more power....
