Wastegate help

**JET** · 03-08-2005

I would do an external gate off the O2 housing. TiAL 38mm may work, but I would go bigger. My turbo is basically identical to yours, but with a mitsu turbine housing and I run a TiAL 40mm.

I have heard that controlling boost is a problem with the external gates.

Tell me more, it is all new to me.

Is 38mm not as good as 40mm?

Will I be able to run 30-40 psi with an external gate?
