Let me know how it fits. I am in the same situation with the pipe from the turbo to intercooler. Did you have to purchase bote pipes or just the one you need?

Need a set of intercooler pipes for a precision front mount intercooler. Need for an 87 GN. Will take just the one from the turbo if that is all you have. Asking for both because who wants to sell only one.
I have a set of Ross forged pistons with stock rods, that have been bushed and the side beams polished fo,r a 4 inch bore 4.1. I believe they are for a .035 over 4,1 block.
A friend of mine over on the turbobuicks.com site did his own TA block build at home in his garage. He did a complete write up on the build in the stage section.
