# I've sure Nissan designed there normal operating temp at --->

Since that is where the stock temp gauge is sitting happy in the middle. I'm sure the VE is designed to operate around 180-200 in 75 degree weather. The stock tstat is 180. The low version is 170 (which Stant version opens up at 180). I know emissions get worse when you run cooler. Every car has that problem. Alot of V8 domestics go with 160 Tstats and it does WONDERS. Gas mileage should get worse, but I'm unsure how much worse. Probably very minute. I will definitely keep an eye on my coolant temp gauge. It's the best gauge ANY car enthuiast should have. Matt, you need one BAD since you race. It opens up a whole new world. Tomorrow, I'm dedicating to my ram air inlet. It's all fabbed up and looking VERY prettty. I just have to install it. After that, put tires on my Millenia wheels or start removing sound deadening for weight reduction purposes. : My only question is what does that do to the rest of the engine? Nissan designed it to work at those temps.. was it an efficiency reason, cooling ysstem capacity, engine wear, emissions, ????? : There's always tradeoffs on that stuff. : Let me know how it looks after you've played with it a while. also make sure you don't lose that part number, so I can buy one. :) Replys:
