1) Vaccum line, what Inner diameter does one buy? JCwhitney lists 3/32, 5/32, 7/32, 7/64, 9/32....my guess would just be 3/32.

2) T's for the Vaccum lines are 1/8" Correct?

Does that seem like the right selection of piping(found off http://www.cse.uconn.edu/~yelevich/turbo/turbo.html)

I guess thats about it....

 

the T for the vacuum line should match the ID of the line..

figure out what your bov/wastegate/turbo inlet/outlets are, and get the lines that coencide.
