Hello ive got two questions i think that my turbo is on its way (130 bhp diesel) basically after remap which ive done two months ago on low revs turbo whistles and secondly it smokes quite badly (and i think it is not as powerful as it was) . So i was wondering can i fit turbo from 150 bhp Leon or golf? Can I gain something with this sort of swap and secondly can i fit back exhaust box from face lifted Fr to my 2003 Ibiza i think i will have to cut part of my bumper but i am ok with that. Thanks for help all the best?
