Yes, remove it. Its the pre-heater for the airbox to be used in colder climates (look at the summer/winter flapper on the orange airbox). This is what it looks like once its off. It probably isn't doing any harm, but isn't doing any good either for your situation.

Have you ever considered getting a used head with the stock cam and having it rebuilt by a reputable local engine shop? I still think the root cause of this problem is the California Datsun / Datsun parts LLC engine and head combination that you're running. You're throwing good money at bandaids and not fixing the cause of the overheating. Sent from my iPhone using Classic Zcar Club mobile

Dr. Googles says "Mufflers deal with temperatures that range between 300 and 500 degrees fhreneheit. Due to the intensity of heat produced by an engine's emission system, most exhaust systems are built to handle an excess of 1,200 degrees. In addition, Gasoline exhaust gases burn in the range of 1,000 to 1,400 degrees Fahrenheit."

These spacers are available in the 4x4 world all over the place for raising (leveling) a truck out. I've heard great things about the billet spacers & am looking at a set for my xterra, although I haven't pulled the trigger yet. I would have to think that this will resolve the problem you face with the rear sitting lower in the 280z

The air galley is the device that the smog pump pushes fresh air into the exhaust manifold with. Most of them are leaking or damaged by now.

The popping on deceleration is unburnt fuel leaving the combustion chamber into the exhaust system & combusting (burning) due to the heat in the exhaust. I solved mine by removing all of my smog gear, capping off the air galley and leaning out the carbs. Sent from my iPhone using Classic Zcar Club mobile

I have the MSA stock manifold kit and really love it. Sounds much better than my twice pipe setup and bolted up nicely.

I'm not using my Altima spare & happy to let it go for $50, located in Chicago for anyone local.

I have a first generation Nissan Altima donut that works well. Its thin enough so it should clear the bigger brakes. Here's an example: http://www.ebay.com/itm/93-97-Nissan-Altima-OEM-temporary-spare-rim-tire-donut-wheel-125-70-15-/192039515577?fits=Model%3AAltima&hash=item2cb67275b9:g:WlgAAOSwEzxYPHzU&vxp=mtr

Try putting fuel pressure regulators between the metal fuel rail and each carb (2 regulators) and run. Stronger psi through the main fuel line (bigger pump). I would not for for a fuel injector pump as 60-90psi will blow out the fuel lines, but a steady 10psi should prevent percolation Sent from my iPhone using Classic Zcar Club mobile
