I doubt you'll be able to remove enough to really make a difference w/o seriously compromising the car's usability. I helped a friend lighten an M3 once, and we wound up with only about 80lbs of "excess" (spare tire, jack, owner's manuals, etc.) If you're serious, think about losing the seats and installing a fiberglass racing seat, replacing all the windows with plastic ones (just glue them in and lose the motors and regulators while you're at it), toss the carpet and headliner, speakers and radio, external mirrors, chuck the exhaust from the turbo back and just run a straight pipe into a glasspack -- you could probably lose 4-500 pounds! But if you still want to be streetable, I wouldn't waste a lot of effort removing parts that'll only net you 10-12 lbs (unless it'll also boost your power, like going with a lighter free-flowing exhaust).

 

Wow thanks you guys that was a lil more than what I wanted to do. I just wanted to remove unnecessary equipment that I never used. So as of right now its just the headlights washers that are going to be taken off and ill do some more research into what else I could remove without hurting the cars drivability

 

The links I posted aren't going to do much for you in the way of weight reduction. I posted them because you asked what could be removed from the engine compartment that wasn't 100% necessary. Most of that stuff is rubber and plastic, I'd be surprised if it weighed 10 or 15lbs all told. Removing the PCV/Evap/ system and slimming down the vaccum set up is more to simplify things under the hood. Fewer things to break, and easier for you to make sense of what you're seeing when you look at the engine.

 

Thank you CCA4.

 

Regarding 'cleaning up things': One of the first things I would like to get rid of (and standard procedure for my other modded car - 99 Cougar) is eliminating the EGR circuit entirely. On the Cougar, every tuner asks 'want to tune out the EGR'. Haven't found anything good for the Audi (currently fighting EGR code with likely plugged passage on my 2.8 2 valve).

On the 98 1.8T AEB, I 'ommitted' the 2nd horn when installing the FMIC. Unintended, there went another 1 lb.

Weight savings: in addition to spare, jack (and junk in the trunk), you can save 50 lbs by
- driving with an almost empty gas tank (1 gal is weighs roughly 7 lbs!)
- empty washer fluid (the one in the A4 is HUGE, likely due to the high pressure headlight washers?)

Did someone mention getting rid of the AC?

 

In phoenix ac is a must.
