4 Port N/A to 4 Port Turbo NEED HELP
So here is the run down. I have all the parts off of a blown S5 Turbo II motor laying on the floor in my garage. The stock ECU, MAF, Turbo, Turbo Manifold ETC ETC ETC! I need to know from an expert (turns on the Aaron Cake Bat Symbol) what I need to do in order to get my car running at factory boost until I get my aftermarket intercooler/piping.
The block again is a Turbo II 4 Port. I have 550 primes and 700 secondaries with a walbaro aftermarket fuel pump. This block was literally built to be turbo'd and we just never got around to turboing it until I was able to put together the parts. Let me know your thoughts and the build order you would do this in, because I am about to disable my car by ripping off the manifolds and starting the bolt on process.

Factory boost levels... No. Safe boost levels.... Yes. And here's how:
If you're really wanting to use those secondary fuel injectors, look into an Rtek 1.7 for now. Reasonably priced and effective! You should also buy an adjustable fuel pressure regulator, as the Walbro fuel pump provides higher fuel pressure than the stock TII fuel pump.
Also, since you've got the turbo out, port the wastegate... Yes, even though the S5 turbo has more efficient wastegate passages, it still wouldn't hurt to port them. Keep in mind that wastegate porting is more of a precautionary modification.

I have the stock ECU and a fuel cut defender switch (that I don't intend on using until I have all the gauges). Essentially this is what I am looking to do; imagine if you went out to your turbo'd car removed everything that made it a turbo and put in a N/A ECU, upper & lower, exhaust manifold, and oil pan. What would I need to do to put everything back on there and be up and boosted again. I just want to make sure before I tear off everything that lets my car run and get bolt happy that I don't encounter the "****! I didn't know I needed that". Essentially right now I am just trying to run stock boost to my car because it was built for a turbo. I run rich and idle rough because I have a bridge port and turbo II rotors inside the housings right now.
So, pretend as if you converted your Turbo car to a N/A for some crazy reason and tell me what you would need to get it back to being that beautiful Turbo ride it was.

The FSM has broken down pictures of every component and how they assemble. In general, install LIM, turbo manifold, turbo, fuel rails, vac lines, acv, UIM, TB, IC, intake, ecu. Checking all the way that the wire harness routes to everything you need it to. Done!

WTF is an FMS? You use a **** ton of acronyms... LIM ACV UIM TB IC...
I don't understand your acronyms lol

Okay okay okay...........
First things first... What series car? What series engine? What series engine parts? (Manifolds, radiator, turbo, etc.) What series electronics? What series are or is everything???
We need to know these things before you go about telling us that we don't understand what you're talking about!
The reason I even mentioned the Rtek is because you're wanting to use a fuel pump and secondary fuel injectors that the stock ECU cannot handle. I'm not spewing ****. Aaron Cake is a great rotary enthusiast with great knowledge, but he's not the only one who knows what he is talking about. He's a busy guy... He can't save everyone's *** all of the time.
Plus, most acronyms are posted in the 2nd Generation FAQ. -> 2nd Generation RX-7 FAQ

From your description, you seem to be doing an S5 turbo engine into an S4 NA chassis, so read up on those types of threads.
The Factory Service Manuals (FSM) are available electronically http://foxed.ca/index.php?page=rx7manual
Pay careful attention to the pictures in section 4b, Fuel and Emissions - Turbo

Alright a little more background on the engine. You are correct it is a S5 swap in to an S4 chassis and it is indeed a 4 port Turbo II engine. Emissions don't really matter for my car because we are not an emission state. I have no smog, no AC or AC related piping. We are literally talking about an S5 TII 4 port with no fluff, it even has a dual pulley on alternator to compensate for all the missing ****.
This is literally a situation that I throw in ECU, MAF, upper & lower, exhaust manifold & turbo, connect the oil lines AND... Boom I am out of what else needs to be done, hence my need for a more expert advice on a pretty unique and custom setup. The injectors pump etc has always been meant for turbo, I just don't want to blow my engine n00bing it up.

I ordered in the lower gasket from racing beat today. I think that I have everything to go ahead and attempt this swap as long as I am operating within the stock parameters of the ECU. I also have acquired a fuel cut defender switch to prevent the rear housing from leaning when experiencing any kind of boost spike. The turbo is a factory turbo/wastegate/blow off setup. I will be posting pictures in a new thread as I go through this. While I am waiting for the gasket I am going to go ahead and clean up the lower and upper intake to give it a cleaner look, because we all know that adds horsepower >.>

So, you still plan on running a Walbro 255 lph fuel pump with 720cc secondary fuel injectors on the stock ECU and stock FPR?
If this is the case^... Good luck.
All I'm saying is Rtek 1.7, adjustable FPR, and port the wastegate. The money you spent on the FCD could have been used toward the Rtek. (The Rtek has a built-in FCD and is as simple as using the stock ECU. It will compensate for your specific upgrades, while keeping your boost well within reason.)
*FPR = Fuel Pressure Regulator
