Watching along here...
What sort of gearing are you running with those 35 inch tires?

Almost finished. Just need to clamp down the down pipe and modify exhaust.

All done. I guess I better get the good beer for the exhaust guy. Because, that weld job he did on the down pipe was right on the money. It mated up with the rest of the exhaust system perfectly. I can't ask for a better fit. And, even with the heat shield, I have just more than an inch of clearance from the firewall.
I haven't driven it yet. Got a family function to go to tonight and have to get cleaned up. Will take it out for a spin tomorrow.

Nice!
I like the cut down 6 BT exhaust manifold you have been running as well. If I was to do a 4 BT swap I would do the same trick on the manifold.
Another vote for the good beer for the exhaust guy.

Drive test completed and it appears the turbo upgrade was successful. It does seem to have more pep. Boost level went from max 12 psi (H1C) to 22 psi (Super HX30w). I'll push it again to see if boost will go higher.
And, here's the interesting thing. EGTs went from 1100 * at 70 MPH (H1C) to between 1000* & 1050* at 70 MPH (Super HX30w). It didn't hit 1100* until I got up to 75 MPH. Before and after tests were on the same stretch of level highway.
And yes, I did remove the silencer ring. So, it's a whistlin'
I'm a happy guy on Father's Day.
