I have a 1990 Mazda RX7 turbo that I have been building for over a decade. I gave it to a shop to put it together a few years ago and it was never put together after all the parts were there to the puzzle. I got it back after that shop closed down and I got my car in a very bad shape. I need guidance putting it together. As of now, I need to know how to connect all vacuum lines around the fuel injectors after you take off the intake. I have a series 5 13B with a series 5 lower intake and series 6 (FD) upper intake that was rebuilt by the same shop. Since I’m not using the original series 5 upper intake, I need to know how the vacuum lines that originally connected to it, how and where will they connect to the series 6 (FD) upper intake manifold. I have the s5 to s6 adapter from Rising Rpm. I have pictures so you can see what I mean. All help is welcome. I have been building my FC for over 15 years and I want to finish it this year if possible.

Need help connect all vacuum lines from a series 5 13B engine to a series 6 (FD) upper intake manifold

What do I do here? This line looks like it’s coming from the turbo and it’s not long enough to connect to the oil cooler

Thank you so much for that vacuum diagram. You wouldn’t happen to have the vacuum diagram for an FD3S? That would help cross reference between both diagrams
