Cam, head work, rods and pistons are not needed, if you think you'll want more power later on then of course that's different, on top of them you'd need EFI management and injectors to have any hope of it staying in tune too.
For 250bhp all you need is a turbo and a chip.not a chance.
My s2 had a bayjoo chip,mongoose exhaust,pro alloy front mount,uprated actuator,modified metering unit,Kent cam,low miles solid good running engine with correct compression,bleed valve instead of the Amal valve and that made 194 bhp atw on Ava's dyno back in 2005.
I asked why other rs turbos with an exhaust and chip were claiming to be well over 200 bhp and was told simply "they are lying" and my engine was putting out really good power for essentially a standard engine and if I wanted more it would be a zvh or something apart from a 1.6 cvh with standard internals.
If anybody's 1.6 cvh with a turbo and chip are making dyno figures of over 200 bhp then the dyno needs calibrated.
