might have been answered a load of times before, ive had a search but cant find what im looking for..

basically - why would you want a cossie engine with low compression pistons.... what are the benefits, why would yuo need them and what does it affect with the running - are they only for running immense boost engines?

what would happen if i fitted a complete low comp bottom end, i take it my car would need a different chip and setup...?
