S1 VVC - Why only 143bhp, when the S2 has 160???
Discussion
S1 uses the older MEM2J engine ECU, the S2 uses MEMS3. It’s not impossible to convert over but requires a bit of work, including a new engine wiring harness, coil packs and cam cover.
From memory there are also minute differences in the cylinder head, but as for what precisely these are, someone like Dave is best placed to advise.

S2 111s also has the girly longer geared gearbox not the close ratio box in the S1
It is too long having tried a 111S. To be honest sitting at 3-4krpm on the motorway is no chore with a K Series, it's in its happy place (especially with cams). Mine is a standard S2 with the close ratio gearbox but running 165hp on ITBs/cams. Best of both worlds and not much heavier than an S1.
