Stupid reply Gareth, please don't become another pedantic PF clown, i said, injectors, management and mapped to suit with a decent amount of boost, very few people can map the frst's properly, hence rather than mess around with it, put an aftermarket management system on along with some decent injectors then get mapped with some more boost, it should then be able to make much better power, if he wants more power at a later date then he can look at different turbo (4x4 saff one on a .48 would be good) forged internals etc.
