The Stark Automotive Honda K20 conversion is starting to roll out in customer cars. The Stark kit uses the DTA S60 ECU rather than the OEM ECU + hondata and also comes with some clockwisemotion options such as their baffled sump
It is early days yet and the first customer has only reported a couple of niggles (gear linkage problems and front clam fitment - both easily solved) and an issue with a paint job which is hardly of interest from the evaluation of the conversion.
No dyno runs seem available at the moment.
Pictures of the engine bay show that the conversion is not quite as neat as some but then again it is an early car. The wiring by the exhaust manifold could do with some shielding though.
