uhhhh sorry man u need $$ for most every single mod that actually does something usefull... the only FREE mod i know is taking out this useless air box thing located very bottom-right of your engine if your looking at it. remove a few bolts and it just pops out, makes your car sound louder when u gun it also. Just make sure your not removing your air filter instead of the box thing heh heh i passed smog without it so its no big deal

It's free to clean stuff up. Remove the throttle body and clean it out. This isn't an upgrade.. but it will reclaim some loss of power frm an aging engine. It's also free to chop off your exhaust before the cat!.. not very wise, but you'll get some power.

The following was posted by member ka24de_510. He was nice enough to buy this off ebay and report back to us on EXACTLY what it is. I haven't tried it yet.. but it's almost free and might just help a little:

"free (almost) timing advance "kit" I posted this in the online mechanic section, thought it might be more accurate to post it here.

ok guys, here it is, as promised.the kit that people pay as much as $20 for on ebay...

parts:a 3.3K ohm resistor. go down to radio shack. you'll most likely have to buy a set of them, it should run about $1.29. if you can buy only one from somewhere (anywhere) besides radio shaft, a single should cost 5 cents. the colors for this resistor should be orange, orange, red, and the last color isn't all too important.

directions: bend resistor into U-shape. find your air temp sensor, it should be right next to your MAFS. disconnect the harness from the ATS. there should only be two wires attached to it. (if there are three, you've got the MAFS. put it back.) insert one lead of the resistor into one plug, and the other lead into the other plug. it doesn't matter which way. tape it all over with electrical tape so that it stays clean and put together.

that's it! make sure your loose unused harness stays out of the way of belts and other goodies. I would recommend leaving the harness in the engine bay so that you can quickly go back to stock if necessary.

other side notes:as mentioned previously by someone: try a potentiometer- cheap variable engine timing.from the inside of the intake hose, the air temp sensor looks like a little bridge attached to the side of the hose. there is a thermistor (little orangish temp-sensitive resistor) underneath the bridge, along with some other little thing. (capacitor?)"

You can take the y-pipe off your airbox. Others have claimed an increase in power. I didn't really notice much of an increase, but it will sound louder at WOT.

To advance static timing all you need to do it rotate the distributer clockwise about 2 degrees (It will allow you to rotate the whole assembly roughly 6 degrees). Two bolts a boom your done. You can remove the resonator (that box that is in the fender-well connected to the air-box) for a little bit better airflow to the air box and a somewhat louder intake under WOT.

if you have an auto you can unplug the tran fluid regulator, that made a huge difference on my car.

unplugging the auto fluid regulator is not something id recommend, i did it just to see and after 5 minutes of spirited driving i could smell something like clutch. I think all it does is dump the clutch for every shift and thats not good at all. I could see undoing it just for a race but not for normal driving less you want to get a new transmission...just my opinion

My free mods include:

Removing Intake resonator

Removing Mechanical fan (ok, couple dollars in wire and stuff for electric fan)

Removing exhaust resonator (yea, yeah couple dollars for pipe and clamps to replace it with)

Alltogether I'm very pleased with these mods and thier power increases.

I will try the resistor thing tomorrow!
