Ok guys I have a bunch of questions I need to get answered professionally before I tear into my rx7.

First off I have an NA 88 SE

So I have an s4 6 port 13b.

My engine blew one of the smaller coolant hoses that seems to run under the upper intake manifold so I logically began disassembling the engine to gain access taking careful precautions to make sure I know where everything goes. While I have everything disassembled, I would hate to replace the hose with something of the same inferior design only to have it fail again so I would like to replace it with something better.

I want to replace all of the vacuum hoses while I am there but I also want to eliminate anything not needed. I was thinking about seizing this opportunity to delete the EGR, ACV, Airpump, OMP, etc

Is there a reliable method to get 5th and 6th port actuation without just wiring them open? I like to fix things not rig them. The compressor method doesnt really seem smart because the compressors arent rated to run constantly. Has anyone done a full write up on an actual solution to the 5th and 6th ports? I am handy and am a new tech so I am still learning, but I DO follow directions well and I would like to make my trip under the upper intake as useful as possible by deleting anything unnecessary. I would like to replace what vacuum hoses are left and I want to be as economical as possible with this whole process. Id love some input on how to proceed.

I currently have the alternator out, the throttle body off, the throttle cable disconnected, the bac off, and I want some input from someone with experience on what to do next.

Id love to hook up an rpm switch to the ports if there is some way to get some air pressure to them without an external compressor. Someone school me.

The s4 ports activate off of back pressure from the exhaust.
I think RotaryRocket88 has a rpm switch thread on it you may want to look at.
