its a standard bottom end and its running a spacer plate from ferriday engineering not sure how much it will cope with its about 15psi at the moment,the engine is in good condition though its only got 30k miles on it,i wish when i bought it yrs ago id strengthend the bottom end a bit and put better pistons in,what sort of price would different management be fitted? Been looking at motorsport developments site they list a type of stg 3 chip would this be of any use to me do you think?
