Hey,

I have a 1993 FD w/ a Single GT40R. I run a Blitz SBC I-Color boost controller. For some reason after removing my manifold and turbo to replace the manifold gasket, i can't boost over .50 bar... .7psi. I assumed I wrongfully but the vac lines on the WG backwards, but I've double checked and they are fine. My boost controller is set @ 1.00 bar (14ish Psi). I can't figure out why it wont boost more?

Thanks,
Geby.

 

pressure test for boost leaks first. do a search on this here and in the single turbo forum. you hook up an air compressor to the compressor inlet of the turbo, pressurize the system, and feel around for air escaping.
