Hello after some help I've got a 105 bhp Audi A3 tdi witch is mapped and the turbo is not liking it very much so I'm going down different injectors and turbo route .. Mine is a 1.9 tdi , my pal has a set of 140 bkd 2.0 tdi injectors for £100 witch I think is cheap will these go in and will I need a bkd 140 turbo again will this fit ?? or do I go down the route of 1.9 golf and Bora tdi 130-150 injectors and turbo?? also what else do I need to do or is that it to run these ?? I take it I will need to re map again I understand it needs a front mount Deffo .. Would apprciate advice very urgently as either way I will be purchasing everything tmrw
