Alright this is my monday research that i have compiled for the 240sx and the 300zx here it goes:

I've seen a number of posts through the years about "how much does my car weight." or people who just are not sure and confuse the weight listed on the inside of the door as their cars actual weight. I searched around and found a few years weights or a model type weight. So I compiled a list of curb weights for the archives here.

These weights include all standard options, T-tops, and a manual transmition. For slicktops subtrack 33lbs. <---(Thanks Z PYRATE)

Twin Turbo Z32:
1996 - 3502 lbs.
1995 - 3517 lbs.
1994 - 3517 lbs.
1993 - 3474 lbs.
1992 - 3474 lbs.
1991 - 3474 lbs.
1990 - 3414 lbs.

N/A Z32
1996 - 3320 lbs.
1995 - 3332 lbs.
1994 - 3332 lbs.
1993 - 3219 lbs.
1992 - 3219 lbs.
1991 - 3219 lbs.
1990 - 3219 lbs.

N/A Z32 2+2
1996 - 3401 lbs.
1995 - 3413 lbs.
1994 - 3413 lbs.
1993 - 3313 lbs.
1992 - 3313 lbs.
1991 - 3313 lbs.
1990 - 3313 lbs.

N/A Z32 Convertable
1996 - 3401 lbs.
1995 - 3446 lbs.
1994 - 3446 lbs.
1993 - 3432 lbs.


And thats what I have found. If anyone finds different info point it out and I will gladly edit this post. This is the best I could do, and didn't have many sources to verify with. Sources include: edmunds.com, cars.com, and caranddriver.com

this is the specs that i also found from MODERNRACER.COM on the 240sx 1995:

So in theory the engine weight is what makes the 300zx suce a heavy car and if i drop a SR20det in this will remarcabally reduce athe weight of the car. plus IT IS DIFFRENT...nad diffrent is good so.. let me know what your opinion is on this situation.. thanx for the input. i got to call doug at z fever. thanx for the info..
