got the new radiator in, and it holds coolant like it should. and the new fan housing doesn't rub like the last one did. over the weekend I took the supercharger and lower intake manifold off to replace with the L36 lower and L26 upper intake manifolds. the studs that held the rear side of the fuel rail had broke off, so nothing was holding the rear fuel injectors down, and they developed a vacuum leak. I could have just removed the supercharger and repaired the holes, but I figured I might as well install the N/A intake for the future turbo install.
I ran into a few problems, the first one was the angle of the fuel injectors going into the heads was bad, so I used some lock washers to lift the fuel rail and give it a different angle, I also cut the fuel rail and used 300 psi fuel injector line with fuel injector hose clamps. It took a few tries to get the injectors to seal, but it is good now, no fuel leaks and no vacuum leaks.
the other problem I am still having is with the throttle position sensor. when I am driving with the cruise control on, if I push on the gas pedal, nothing will happen, but when I turn the cc off, everything is fine. the other symptom is that after I have gone for a drive and put it in park, the idle will surge from 500 to 1500 rpm and then the engine will die within a few duration's. I changed the tps and the problem came back, so I think it is either a wiring issue or a pcm issue. when I had the north star throttle body on, I had tps issues then as well.
Here are some pictures of the current configuration, my vacuum line routing is probably jacked up, I am open to suggestions.
