The aftemarket for the Z is huge, and maybe they will have swap in kits for the new 2.3L and future 2.0L engines coming from Ford.
Someone got a new 2.3L engine into high HP ranges. From Focaljet.com:
"Making the 2.3 Duratec engine available in the Focus is an excellent beginning. If you haven't been following some of the posts, you missed out when KSGerry posted some dyno figures for this engine, naturally aspirated. 275 hp on methanol, 245 on gas! "
"The current "kick-butt" stock oem Duratec engine is the one advertised in the Mazda6 commercials. Their turbo-Duratec has numbers around 275. This is the same engine (no-turbo) going into the Focus."
"Note...My Duratecs have been converted to testing for circle-track applications. There have been some modifications. See:
www.circleperformance.com or
www.minister-power.com"

Ford's I4's are going to kick some arrogant Civics around.
