6.0 external wastegate? anyone ever done one?

[rollincoal93]

i just got the pedistal and everything to switch over to the T4 flange turbo and got a really good deal i couldnt pass up on a 66mm just its not wastegated, so i need to figure out what i should do to keep drive pressures under control and not blow the turbo.. wondering the differences between a blow off valve or an external wastegate and if anyone has ever done this on a 6.0 and if they have some pics of their setup to help would be great.

If the exhaust housing big is enough you shouldnt need a waste gate.

^^^Yup

If the exhaust housing is smaller, then you could install a blow off valve to eliminate turbo surging, but that won't help with the drive pressures. If you are worried about drive pressure or plan to run nitrous a wastegate is the way to go. You can make your own custom up pip to run the external gate. I have seen some cool setups like that. One that I though was a good idea was to use the factory up-pipe, and plumb the wastegate in where the EGR was. That minimizes the amount of fab work that is needed.

If I were you, I would say run it as is for now, and monitor your backpressure and wwatch for surging. If you think you need a wastegate, you may be better off to purchase an internally gated exhaust housing for your turbo.

shouldnt need one with a T4 was side housing?

I have built one on a single before its not that bad at all. But I just had a dump pipe and didnt have it go back in the down pipe.
