In a message dated 01-06-06 18:36:13 EDT, you write: << If it's a 20v NA engine, I agree, I'd like to know too, that's fairly impressive :-) >> That's completely a reasonable horsepower figure - for a race engine. John Milledge can build a 280hp 2.5 8V 4, I can easily believe a 2.3 20V 5 with 275 - but it wouldn't last long - maybe 20 hours at speed. Later! Carter
