I run 44psi front and 42psi rear in the Civic. With the same in the Accord. The psi helps the Civic some. Its just a flat out crappy coaster IMO. The Accord Coast like a dream. With the psi where its at now I cant imagine another car that coast like it does. Tires wear even, road noise goes down, with a tad firmer ride in both. Even with tire pressures up the wife cant get mpg out of it. She shouldnt have a lic IMO. Im suprised she hasnt wrecked it yet.

As for mods. The 5AT in the Accord ruins the car IMO. Just guts it right out. I could rip the intior out put light wheels on it carbon fiber hood and trunk lid and she still couldnt get better than 30 mpg out of it.

The Civic on the other hand would be a car worth modding. If the intake and exhaust mods helped any with torgue it would be great! Cause thats what the car needs. GRUNT! Lighter wheels would be nice. But they are big $$$

Honda built the Hybrid for all out mpg. While they gave some life to the EX's. And turned Si loose. I cant help but get alittle pissed when I open the hood of my EX and see the intergrated exhaust manifold into the head. I honestly beleive if they had built the 1.8 with no vtec it would do as good as the hybrid. IE a HX. Which IMO is why there isnt a HX. the one place i know I could have got some grunt out of my EX they saw fit to take away with the head exhaust manifold design.

So the only car Honda saw fit to build that would mod out good was the Si.

Ive seen where folks mod hybrids,, but its all ICE mods. The cool thing to mod would be the IMA. Bigger electric motor, better batterys, better software. Ive seen wheel mods on hybrids and just dont understand that. Ive yet to see one with any of the high dollar ulltra light wheels made for racing that would be good wheels for looks and mpg. Im waiting to see my 1st winged and fart canned hybrid.
