Re: Junkyard Turbo Wastegate WG Pressures
 

A little bit of misinformation about starion/conquest turbos.

First of all, its a TD05-12A

up to 87 ran 7 psi, and after that they have 3 port wastegate designed to run 7psi up to 4k rpm and 10psi after that, but you probably won't be able to use the boost solenoid for them, so you won't be able to use this feature.

This is how you should set it up with a MBC http://216.77.188.54/coDataImages/p/...67MVC-004S.JPG

The hose goes to your MBC.

If you don't have a MBC and just have this hose run to the charge pipe, you will get 10psi, if you do the other hose, you will get 7.

Im a toyota guy myself.

CT26 stock wastegate pressure yield is 7 psi on the spring. The 5 PSI posted is incorrect.

Re: Junkyard Turbo Wastegate WG Pressures
 

Journal bearing GT28...9psi. Off suzuki "trucks" and Mclaren edition pontiacs. Same WG.

How do you know if you have a Stage 1, 2, or 3 Garrett T28?

Re: Junkyard Turbo Wastegate WG Pressures
 

86-91 Mazda Rx-7 is 5psi. With a 3" exhaust they'll do 7psi. But the wastegates must be ported with w free flowing exhaust to prevent boost spikes.

good info to know

Re: Junkyard Turbo Wastegate WG Pressures
 

A buddy of mine has a auto Supra and his stock boost gauge reads 5 PSI. Is that because its a auto? Do the manuals hit 7 PSI?
