1.75"
Turbo Mini Forums

Hi all,
Just a quick question, I have a 1.75" twin box superflow system at the moment and managed to find a metty turbo engine, just wondering if using a 1.75" exhaust would course damage to the turbo in the long run, i know that you are looking for the biggest difference in pressure from turbine to downpipe?
Thanks

it shouldnt do you just wouldnt have as much power, as long as it has the popet valve and low boost or a dump valve to stop the turbo stalling (please correct if im wrong) then there shouldnt be a problem. if the exhaust was a pea shooter size all the way then you may get problems.
