Lightbulb Similarities Between Ti-VCT and Previous Generation Duratec


I've been researching this new engine for months and finally decided to join and reach out to the experts.

The sticky above is great but doesn't address some of the areas that I am interested in. My application is to replace the Duratec engine in my Caterham with the new GDI Ti-VCT version.

Is the block of the new engine dimensionally the same as the previous? i.e. motor mount locations, alternator mounting, bellhousing bolt pattern, crank and bearing dimensions, etc?

Would anyone happen to have a clear shot of the intake ports on the head? The exhaust ports appear to be very similar (similar enough to bolt up the previous generation header). However, the intake side looks drastically different and I'd like to better ascertain what all of the differences are.

I came from the MR2 community where I built a high-powered n/a combination of a 3SGTE and 5SFE engine. Has anyone disassembled this engine yet and be able to comment on the ability to bolt the DI head on a previous generation block (if the new block is not dimensionally the same as the previous)? Is the previous generation 2.3l block really taller as some have suggested or is it just the crank stroke that is increase as is normally seen?

Thanks very much in advance,
