How light can u go? or a crx...

im soon to be buying a crx and i got a couple weight questions

i was just wondering how much less can u go below the stock 900kg????
what i mean is that how much lighter will the car be when u take out the carpets, sound system, spare tyre and so on but to keep the essentials such as dash, seats etc

how much does a stock crx engine weigh to a b16a??? it shouldnt b too much difference?

also, does mayb like 5kg(placed anywhere in the car) have any effect on a speed of a car ? when drag racing?

did you search, there is tons of post about this.
a quich search will find you your awnsers. :bigthumb:
