I've been lightweighting my 97 Protege 1.5L for the last 4-6months. I've hit 159 lbs so far. (Using WalMart fish scale on everything). Including a rotating mass of 17lbs.
I'm concentrating on lightweighting because of my commute. It is 5.5 miles one way with 22 lights. Top speed 35, actual average speed on a single tank is 22mph. So since I am starting/stoping 15-20 times weight is where I am concentrating.
Some numbers:
PS pump and hoses = 15lbs, A/C = 45lbs, backseat = 7bs, passanger seat =37lbs, sparetire/jack = 27lbs, passanger airbag and glove box = 13lbs. 155/80/13 on VX rims saved 6lbs per rear wheel. (I'll do the front ones later).
Future ideas:
LED lights everywhere, smaller alternator, small battery.
Smaller radiator.
Remove 13 gallon tank (Takes 2 months between fillups, carring around 36lbs of fuel first month) replace with 5 gallon spare tire well tank. Belly pan at same time.
Lexan for rear windows, permanently up.
Remove heater core, replace with small electric defrost for winter. Car is in San Jose CA
Lightweight muffler, flywheel, crank pulley, waterpump pulley, alternator pulley.
