    Single turbo VR4

    A few months ago i blew the rear stock turbo on my car. I was looking for a turbo upgrade anyway and i was bouncing back and forth between 19ts, 16gs, or single turbo... I saw the thread where someone used a 350z manifold to build theirs about a year ago. After i re read the thread a few times i jumped in on it and bought a set of 350z manifolds to weld up to my flanges. Since then ive been fabricating everything for this.

    Just continuing this thread where i left off on 3si. I have fuel pressure now, but it dies off quickly. Turns out im also leaking gas from where the injector seals on the rail; hopefully this is a quick and easy fix so i can tune the damn thing for idle!

    Very nice. I second the pics. Did you have to move any wiring, or add some heat wrap since I am assuming this is a over the trans setup?

    Pics are up. No wiring is moved. I do have to get a heat reflective sheet to cover the wires

    No, when i put the injectors in i put them on the lower plenum first then the rails on top which must have messed the o rings off because it kept leaking, then one of the bolt holes on the lower plenum to bolt the rails onto stripped out. Good thing i have like 5 of them but now i got to go to the store in the morning to get at least 3 new fuel injector orings
