Maybe your turbo seals are going. Try searching for that... I've heard that they usually fail on the exhaust side, but you should get a lot of blue smoke.

It's probably not oil. Water always condensates in exhaust pipes. Since rotaries have a tendency to run rich, and have an excessive amount of soot in the exhaust, the water mixes with this soot and turns black. It looks like oil, but most likely isn't.

Mine does this also. It could be condensation or something. It's been doing this for like a year now. I don't think it's the turbos because I just did a single turbo and still spits out the same. Take a piece of cardboard and put it behind the exhaust and start the car. Let the oil or water hit the cardboard and let it collect. You will see that it is only water. What happens is the carbon or gas that is build up along the downpipe, midpipe gets spit out when moisture develops after you startup the car. Nothing to worry about. Try the cardboard trick and you can tell whats really coming out.

nice.. ill pm you before i come down. Ill will be bringing the FD in october because of my uncle bringing his 300ZX and wanting to race. He has the greddy twins and dynoed at 600rwhp. He has 30k in mods other than that. With a good single (T78, gt35/40) Im hoping to run him for his money in his "unbeatable car". Get some tough mods before then and we would love to have you come out with us and run. Highway runs

Are you running rich? Does your exhaust smell bad? It could be sooty fuel. When Mindphrame did the turbo simplification he removed the fuel pressure regulator solenoid (he was supposed to leave it intact) and now he runs rich, and he showed me an oily substance that was sprayed out of his exhaust onto the garage floor. Just a thought.

It's on the solenoid rack and is the one closest to the firewall. It has the orange plug. It's labeled as "A" in this diagram: http://www.zeroglabs.com/rx7/images/...oses.color.jpg. It's hard to see, but has two aqua-blue hoses. the one in the rear of the solenoid connects to a small nipple on the inside of the Lower Intake Manifold. The hose on the top of the solenod conects to the bottom of the Fuel Pressure Regulator, which is at the firewall end of the secondary fuel injector rail. I'm attaching a pic. Note that this is the simplification and a very disorganized, rookie job. So a lot of stuff is out of place. It's just to give you an image that the diagram can't give you.
