Update: the 1.5 needle valves are installed and tested and work under 5 psi base pressure and didn't see any leakage or evidence of leakage thereafter. Also opened up the banjo bolt for the turbo journal bearing supply line to allow more flow through the bearings. Last and most certainly not least, the road test. When I first put it back together I forgot to plug the float bowl overflow barbs and whenever the turbo would start to boost, the fuel would get blown out of the carb and the engine would fall flat on its face. Plugged the float bowl overflows and took it for another run and wow! Boost came on in 2nd gear (first is too short and the turbo lag is substantial) and I let off the throttle at 5psi and when I did that the throttle cables lifted off the carb tops and got stuck. Throttle stuck at quarter throttle I had to shut it down and pull over to fix it. Temporarily used some zip ties to hold the throttle cable tops down until I can adjust the bov. Took it for another run and it peaked at 10psi. At that point I was grinning ear to ear. During these test runs I had removed the headlight to lighten the electrical load and I think I will just put a switch to turn the headlight on and off. Video soon to come.
