I am new to rx7 but not new to motors by any means i have rebuilt my fd motor and decided to go with a single turbo setup. i have done all the thing the right way i am running Power fc and 850cc primary and 1600cc secondaries i really need help with is the fuel system and the vacuum system. Do i need two fuel pressure regulators (primary and secondary rails)? And also how do i run my vacuum lines i have a t70 turbo and power fc and 50mm watsegate. Thanks for your guys time. Any info would help -Jeff

 

You will need 1 Fpr, most have dual inlets so depending if you keep the stock fuel flow pattern, (in primary then into secondary then to fpr) or if you split the line and y them back together, or you can run one like to each side of the fpr, there are a fe threads in the first 2 pages in this section on the fuel system. As far as Vac lines, I don’t know if the PFC needs more solenoids, but you will need 1 as boost source to Wg, 1 to FPR, 1 to Map, 1 to BOV, that’s all you really need

 

that should help

 

Thanks guys this should get me started, now i just need to know what vacuum lines i need to run this setup. thanks again all

 

Also does that that fuel diagram work for fd3s/3rd gens as well?

 

Yes it does. That's the setup I'll use on my single turbo FD.
