what tubing was used to go from both turbos to IC, and then IC to intake?
also where did you expand the outlet tube from the Turbo? right from the turbo? before/after intercooler? at the intake?
What wastegates will work well with these setups? the PT61. TiAL 46mm? I'm not sure how you decide what wastegate to use.
whats a good sized IC for these TT PT61's?
Thanks for all the question answering guys!!

i'm also assuming a separate oil pump is required for these turbo's. One pump per turbo? and does this come with the turbo? if not what are you guys using?
or is the stock car system able to supplie the turbos?

No, That is for a single setup. Also, where is that info from?The numbers look incorrect?
The turbos are fed from the motor, gravity drains them back into the motor.
I should add, my setup is in a 71 chevelle.

I got the turbo from forced inductions. The headers are all 321, even the collectors. I made the collectors 100% myself from scratch. They are a double slip fit and do not actually weld to the header tubes themselves.
You can weld stainless to steel with no problems.
Plug changes are real easy if needed.
With big turbos on a street car, you want big wastegates to bleed of the exhaust at low boost settings. For a BOV. a Tial 50mm seems to be the best bang for the buck.

Did you go with the ball bearing/water cooled PT61's?
