Well on top of my soon to be in progress DX/EX turbo project, I have my Daily driver, which is a 1993 Civic Si Hatch. I just replaced the brake pads/rotors/rear calipers, suspension bushings (still has double wishbone, i dunno if thats good?), and the clutch was replaced just a few years back. It has a ecu 'chip' that was placed in it to keep the exhaust valve open a second longer to allow all the exhaust to flow out, being it has a custom striaght-flow resonator exhaust setup and was tuned (and used to belong to) the daughter/neice (cant rememeber at the moment) of Newman-Haas racing (and indy car co. paul newman owns, whom aslo starred in that cars movie, look it up!). I was going to keep this as a DD and eventually sell it because of the minor bodywork i didnt want to get into, but this inspires me to use it for a bit longer. It has 300,000 miles but i could overhaul it with newer parts and etc.

 

I have a 94 dx, runs in sm class, usually the fastest 4 cylinder car there, decent suspension setup but on falken zeix. Suspension consist of type r sway bar(huge upgrade, low cost) ebay coilover sleeves, kyb agx struts. nearly a 200 hp motor in it all motor so no turbo lagg and so forth. Sounds pretty good right now right....well thats wrong for autocross. I have a friend that has been auto-xing for a little longer than I that has a 90 model civic, beat me by little more than a second on a very open course. He has about the same suspension setup except for koni yellow struts and a lighter car. stock 100hp motor but he ran slicks... My top speed through the course was about 78mph, his was about 60...see what is more important yet??

 

you're driving sucks

 

lol I will take this lightly, but to let you know, my tires are what SUCK

 

an ecu chip is electronical....a valve opening is mechanical. there isnt any coarilation between the two. basically your chipped ecu sends diffrent fuel maps to your motor. your chipped ecu can not adjust your valves to open or close any longer then what the cam profile is grinded to.
