Hey thanks alot guys. Really appreciate that. I was looking at a setup on zcarcreations.com, which doesnt have much equipment on the intake manifold like yours does. I dont know html, but ill try to get the image in here.

As you can see its very clean, is all the stuff on your manifold necessary? What does it take to be able to run the car without it? Thanks again.

Well, I would guess that all this stuff is not necessary in a warm climate. What he has done is remove; the EGR valve, the air regulator, the cold start valve. and the dashpot on the throttle body. He has also replaced the fuel rail with an aftermarket unit, dumping the fuel pressure regulator in the process, likely removed the BCDD. He has retained the Throttle Position Sensor (TPS).

The EGR valve is definitely not necessary and can be removed. All it does is pump some of the exhaust fumes back to be burned again upoin moderate acceleration.

The air regulator may not be necessary in a warm climate, but I would want to keep it. It allows air into the engine to help it for the first few minutes of operation.

The cold start valve could definitely be dumped in a warm climate. It injects fuel when it is really cold, like -20 degrees.

The fuel regulator, I think is neceesary, but I don't know enought about it. It keeps the pressure a certain amount above manifold pressure, or at least realative to it. I do not know what these aftermarket fuel rails do, other than looking good.

The dashpot and the BCDD on the throttle body ar eboth useless emissions devices that slow the deceleration of the vehicle. THey can both be eliminated easily.

That is all I know. Looks like a mean setup.
