Been Googling around for build threads or other info from people who've made internal mods to the 4.2 engine (boring out to 4.7 etc.) but can't find much. Seems there's a German outfit called Leo Nardo who do/did this. Anyone got any knowledge of this type of mod? Cost?
Don't think I'll do this with the GS due to it's... ahem, investment grade status, but I can see a 500bhp n/a, manual '05 facelift 4200 as being a permanent keeper in a future where a stick and lack of turbos will be a distant memory... This would be a long term project for me, but need to start my research so I can keep and eye out for the right car, possibly a Cat car.
