How will a gas engine react to an egr delete?

I'm not deleting my egr, I'm wondering what it would do. This is a normal road car I have well use it for example a 99 Honda accord, lightly modified, 35mpg, little more power over stock. I know having a working egr will lower cylinder temperature, decrease nox, and make it burn slower. If it is taken off and the cylinders are hotter what does that do for gas mileage? I assume the effects will be similar to slight timing advance, correct? It will also lower intake temperature too? Do race cars have egr?

Honda Accord Cooling System?

I have a 2005 Honda Accord EX 2.4 L. There's a small black box behind the engine. A hose comes into the box from the engine and a hose leaves the box and goes into the firewall that separates the engine compartment from the car cabin. This box has a screw that goes into the front of it and connects to what looks like a 10 speed bike cable. This screw has broken off and water comes out of the hole just as soon as I put it into the radiator. I need to replace this part but have no idea what it is. Can anyone tell me a name for the piece that is broken?

2004 Honda Accord V6 transmission problems?

I have a 2004 Honda Accord V6. About a month ago while driving down the road it felt at though I had slipped my car out of gear into neutral, my rpms were revving up but I had no power. I took it to the mechanic and he said tranny rebuild. And so we did. I got the car back about 2 weeks ago and on my way home from the shop the shifting of the tranny was not smooth. It jerked me every time I changed gears and when taking off from a stop it sometimes acted as through it was never going to change. I took it back to the shop and he plugged it up to the machine, even though the check engine light was not on and he told me that it threw a bad solenoid code. I left the car with him for it to be replaced. I picked it up a few days later and he told me that it still wasn't shifting as smoothly as he would like, but that he thought that the valves were sticking? And that he had put a pint of something into the transmission and for me to drive it and he thought the performance would improve as it was driven. Now it's been driven over 250 miles and I'm still having problems. A couple of days ago I was at a complete stop pulling out of a parking lot. When i tried to accelerate, I had to get up to 2000 rpms before the car would even begin to roll, then when the jerked hard down into 2nd, the check engine light, the TCS light, a triangle with a! Inside of it came on, and the green dot beside drive was flashing. I turned the car off and all lights went off but check engine.code P0746.

What's a tune-able yet fast Honda?

I've never really been into hondas, or that type of cars for that matter, but seeing my uncles honda accord ex makes me think otherwise. So i would like to buy one but i'm not sure which one. Do you guys have any suggestions on a honda thats cheap yet very tune-able and fast? I do have a H22 motor and my uncle says its a good motor but i'm not sure. Me being a mechanic and working with mechanics can install that easy in another car. So any suggestions?
