[wimdepim]

hey everybody
i have a problem
i want to buy a better turbo
but down here(belgium) is a problem very expensive items
so if someone get tell me what i need to change turbo fuel exhaust ? i would like about 200-220 bhp in the car
and if one of you makes the deals and send it to me i would really be glad
i am running at the moment with a stock turbo with more boost, closed the return fuel line a bit for more fuel pressure and installed a small intercooler from a mercedes vito cdi and got about 175bhp at the moment
i hopesomeone can help me

thanks mates
