Success. May have killed the thread, or hijacked it royally!
Turn the world upside down - ie feet are up and head is down. Gravity you could say would "lift" things towards your feet. Hot air ballons would "fall" downward, and have "weight"
An external viewer would see the hot air balloon therefore as having negative weight.
edit: I may be REALLY tired, and if this doesn't make sense to ME in the morning, I won't be surprised. My failed attempt at a nerdy joke. :?

Adding negative weight... same damn thing as subtracting weight, worded differently.
1 + -1 = 0
1 - 1 = 0
:roll:

But really guys lighten up. there was alot of harsh words thrown around. Cant we just all get along.
Can we start an actual list of best for budget mods?
1 ) JC Chip if you have a M20, M50, S50, etc (not M42 as much)
2 ) 19# / Larger AFM - cheap mods, nice gains
3 ) Suspension - stiffer, lower
4 ) Summer-only tires
5 ) Light, wide wheels
6 ) Performance brake pads
7 ) Suspension - kill body roll: sways, braces, etc
8 ) Shorter final drive
9 ) Driver

If shorty headers are actually good, I may be tempted to get them, get a str8 pipe instead of cats, then run 2.5 out to an aftermarket muffler, one of these days. There is a local guy with MX headers (rare?) and a dynamax super turbo muffler or similar and his car sounds fuckign awesome.

ROTFLMAO 7 pages of BS +-0 0 -1 -+0 backseats 200hp etc etc. and it was answered on the 1st post
Best performance mod for the money is still a drivers school.
-Charlie
now since we are at 7 or even 8 pages I will bestow the KISS principle
1. driver
2. traction
3. weight (or weightless, less weight, -1 +-01, more negative weight etc lol)
4. torque

He didn't know the difference between understeer and oversteer.
Understanding some basic things, and roughly how hard to push your car can make a big difference.
Still, I want to try the M30 MAF and 19# injectors. Does the JC chip have to be remapped on a dyno to get the best gains, or how do you go about doing this?Moving sale: Everything Must Go!

Originally posted by modifiede30I don't think the heat within the engine bay is an issue as much as the hot air within the headers. I would think the thicker and heavier manifolds act as a heat sink, whereas headers just pass it all through the exhaust, causing it to run much hotter. I've heard the cat burns out much quicker as well.
hes getting angry about the wording of adding lightness because hes angry that you proved he doesn't have 200hp, and he has to get back at you for his loss. anyone can read that and understand what it means...
and i forgot what i was going to say because of all the bullshit i had to read through.Last edited by kowalski; 11-18-2005, 08:36 PM.

Mark D chip has been proven to have significant hp/tq gains over the JC chip. However, most people like the "partial throttle" tuning that the JC chip has.
And what the hell. I'm reading the last 2 pages of posts and just laughing. Discussion of theoretical physics really doesn't have much to do with bang for your buck mods. Jordan deliberatly spoke incorrectly to make a point. Most people try to add things to their cars to make them faster, when really taking things away is often the cheapest option. Ha ha funny funny.

Now this is a question I felt like would help any newbie coming to this site. Alot of people automatically think of the exhaust and wahtnot but what are in fact the best modifications (strictly speed wise, suspension is excluded). From my understanding a Conforti chip in combination with a m30 afm with 19lb injectors and an exhaust you looking at extracting almost all the usable power from the m20. Add a shortshifter for soem crisper throws and to fix up the shifter slop and I cant see any otehr value in doing other things. Is there anything else thats cheap and nets big gains on the dyno?
http://www.davelength.net/car/bigsix.html
based on this stuff it looks like the m30 afm and 19# injectors get you about 5-10 hp max. However, that IS more than nothing and you can do it for around $100. The 4 pintle design of the 19# is also supposed to get you better fuel atomization and better mpg, but we will see. My car feels smoother with the 19# and it pulls a bit harder in higher rpms, but i wouldnt say it was more than 10hp worth. I have a m30 afm going in sometime this week, and a roadtrip down the mountain too, so I will be able to verify all this increased mpg stuff.
m30 afm, 19# injectors, chip, exhaust
you are exactly right for the 'cheap and easy' stuff
you can easily do all those for around $400, and you will be able to tell a difference. The next set of upgrades after that costs more than $400 each (turbo, cams, megasquirt etc) though the gains would be obviously bigger.
stuff like suspension and tires is also kind of expensive (if your cheap/poor), and I would do those when the ones I have wear out and need replacing. Speed wise, unless your tires have horrible traction I dont think they matter, then again I have awd so I already have better traction.
1 ) JC Chip if you have a M20, M50, S50, etc (not M42 as much)
2 ) 19# / Larger AFM - cheap mods, nice gains

You wanna be faster on the track? Take a shit before you drive. That will drop YOUR weight by a good 3 pounds or so.
