well if its money you dont want to spend then i sugest you get out of cosworth ownership asap mate

a turbo rebuild is about .1% of whats gonna be spent lol

it can get out of controll very very quick especially if you dont know the basics like what turbo you have

im not taking the piss out of you mate by any means but what you gonna do when you get a simple miss fire

paying tuners to sort every problem that WILL pop up is gonna hurt your pocket
