cool! Did you get an velosity stack inlet w/your turbo? I know they make nice aftermaket ones for GN's, try & get as big as you can, helps the airflow.
On your exhaust manifold heat valve, are you installing a plate for the to cover it? I never seen that done yet, but I think T-lowe had his all done,but then he went & bought a SPA turbo exhaust manifold & used that instead.
