About 4-5 years ago I worked out the cost of fitting an S2000 Vtec and 6 speed box into my car, Initially the used unit price looked good, however when I viewed the engine/box it was immediately apparent that it wouldn't fit without a lot of work. the engine is very tall and the gearbox/bellhousing is very 'Fat', so I never bothered, going into the details
Eventually I chose a Zetec.
Now 5 years later the Duratex is the obvious choice the power is easily up to a S2000 Vtec - though the parts to make it fit a 7 ain't cheap 😳
So IMO fit a D/tec, for silly power, or if like me you want VFM fit a Zetec
