Huge issues where do I start.....
I just recently bought a 93 Rx7 so far I am very pleased with my purchase for the price. Currently I am still working thru wiring issues but the car seems to have a ton over strange vacuum issues. Also the car smokes at idle which all smells like fuel but due to some of the vacuum issues it leads me to believe that the turbos are done for. I drove the car fairly hard for the first time since my purchase and the car felt as if it lost power and there was a large amount of oil on the underside of the hood where the blow off valve vents.
At this point i questioning the point of spending much on this setup as my plans within a few months is to swap to an LS1. I would however like to drive the car in the mean time. Is my best bet to take the motor out re work all the vac lines etc reinstall and hope for the best? I feel like half if not all of the lines are loose leaking or installed improperly. I knew this car was a project when i bought it and dont mind that fact as that was what I bought it for.
It also has a garbage *** XS power SMIC intercooler installed behind the radiator with no venting as well as a half eliminated air pump that is still on the car missing lines and full of tons of dirt and grit.... lol

the intercooler is fine. plenty of folks run the ebay ICs. Course ducting helps. If you're gonna drop 10k on an LS1 swap in a few months, then I'd just start fixing easy stuff.
Start with a vacuum hose job. You don't need to remove the engine to do that. Just remove the Throttle Body, UIM and TB elbow.

The BOV hoses should be running to a filter to avoid spraying your engine with oil. Don't fill the car with oil, fill to 3/4 and don't let it go lower than 1/2 on the dip stick which will help to avoid blow by. Get a duct for the the SMIC or remove it and find a SMIC with a duct as it's worthless w/o a duct.

I'd start with buying a PFC and removing everything possible and running simplified sequential. You can find them for 600 to 750 and sell it for the same price when you go V8. See what happens from there but that's your best option for a quick easy engine bay clean up and the PFC will allow maximum driving enjoyment along with better gas mileage.

Also is there a write up on how to finish uninstalling the air pump as i do not need it to pass emissions in my state as there are none for this old of a car.

You can find details about removing the air pump by searching for "air pump elimination" or something like that. You'll need a set of block-off plates to do it.
How's the compression of this engine? I'd do a basic compression check and change the plugs before pushing much further forward.
While this won't work miracles, try running some fuel injector cleaner too. FD injectors have been known to cause headaches and if this makes things much better then you might be onto something.
I like Fritz's idea of installing a PFC now. If you have a bad sensor or bad wiring that won't throw a code but is giving the ECU bad values, you can troubleshoot it a lot easier with the PFC since you can read the value coming off of each sensor. With the stock ECU you can't do that without special diagnostic equipment. Not to mention that the PFC makes a good stock car run great.

When working on a car like this one Factory Service Manuals will be one of your best friends.
Two options, the second link is to a searchable set. First one has color versions of the wiring diagram.

2.) https://www.rx7club.com/showthread.p...ght=searchable post#10
Good luck with the problems. Sounds like you are cleaning up one heck of a mess. Thanks for saving another FD from a careless owner. Even if you swap it..

Here is what the car looked like after working on it for a few hours. Under the hood is a mess with tons of missing items such as relay brackets. Since these pictures the body kit has been removed the turbo badge has been ripped off in disgust. Also look at the huge bag of wires i pulled out of the car that were ran everywhere! doing god knows what it runs perfect except the rich condition as is without all these wires i believe the car had some super sweet fog lights and neons lol. It also has 2 turbo times and a huuuuugeeeee $2 monster tach lol

Seriously over paid???? Couldn't i just strip the motor out part the wheels and suspension for atleast 2k re paint the engine bay and sell the roller minus motor and trans for more then i have in it.... I definitely dont see that i overpaid for a car that was driven home... Also note that this is after I have removed alot of items from the car. It is a complete running car. Perhaps I did over pay but it was my only means to an FD even if it means a bit of hard work...

That actually isnt nearly as bad as it looks. I just had it laying there on the fans. They have however bypassed the fan solenoids for a full wide open running fans. The fan relays however are still in tact and the entire harness there is completely uncut or touched some how. Like i said the factory harness is in pretty decent shape other than missing some of the loom holders etc.
At this point I have decided to just head in the direction of LS1 after pulling the intake mani there were a ton of damaged solinoids and it appears the rack was just missing... lol It was zip tied to some lines bah who knows...
I will be pulling the motor this weekend to begin restoring the engine bay and perhaps after its all out it will become more clear and I will be inspired to stay with the rotary but i seriously doubt it... lol

That bag of wires would be mostly stereo wires that were never removed after they yanked out the system.
Why would you part out the wheels and suspension if you are going to put another engine in and use the car?
You are going to strip apart the engine bay, so have it painted to match the outside instead of looking half donkey rear when you open the hood.

I do appreciate the opinion but I don't feel that the damage that I can clearly see is not severe enough to make me abandon the project. all though i do question what do you see that I do not?

The brace that the ast is sitting on in the picture is bend downward in the center. This is curious for frame damage. You may take it to a reputable body shop and have them check it out. If you just plan on enjoying the car the damage may not be too bad. But if you plan on racing the car it may be questionable. OR maybe that brace is just bent...
