Hi people i am currently looking to change my turbo to a ko4 and was wondering what exactly i needed to change as i cant seem to find it anywhere in the search cheers.

alright andy,

not sure many people have done a ko4 conversion here due to cost vs lack of increase in power. Parts can be obtained quite easily from tts etc and some of the parts you would need are manifold, turbo, downpipe and exhaust, injectors and fuel pressure reg just depends how far you want to go and how much power you want, fmic really too!

Am sure having a cosworth you are aware of the different types of turbo conversions on the market,

Try searching Forums - uk-mkivs and vw vortex as well as seatcupra.net for info as these sited have a much larger number of users and have info on pretty much every turbo conversion going!

Pics of cosworth please.........
