Wow,
I found this site yesterday, and I haven't been able to leave yet. Well, actually, I did leave to go to work today. (I commute 120 miles a day, so gas mileage is my new game of choice

I came right back and got on this site again. (Man, what a loser) Anyways, I've been reading all these tips. I have a 92 civic vx model hatchback with 160k that I've had for almost 10 years now!!! I've got all the maintenance up to date and am currently raking in at about 51mpg. I'm pretty satisfied with this, as that was 75-80mph mostly highway driving (40 psi tires), and it has an SI transmission and 14" alloys instead of the stock VX lightweight 13".
My questions are:
Should I put the old transmission back in?
Should I put the VX rims back on? (the 14" are a little wider tire, but still pretty light)
Should I start doing some aero mods? If so, which ones should I start with?
Also, where can I buy one of these SuperMIDs or something similar for my car? That looks like a sweet toy to have
Thanks guys, this site rocks!!!
