Yes they are but I would not be too concerned as I have yet to see a decent running one expect for that hideous lime green one. I believe if you target 250 at the wheels in your 240Z you have nothing to worry about. As for the weight of the 240SX' date=' that was an option for me and the lightest model I found in my research was 2695 for the early notchback model. 2500 does not sound right for a 240SX. Most of the late model SXs with SRs are right at 3000lbs with driver and with 240+hp, you have them covered.[/quote']
Scottie. you saw this 2500 lb 240SX at reynolds.(2650 with driver.. chris is a little dude..lol) he drove up with me from mobile. It was the red one running low 13's ( traction limited). I saw him get on the scales at reynolds. He does not have AC. But other then that it is a stock body. I am not saying that the SR motor will dominate over the L series but I agree if you have a 240Z with around 250rear wheel hp you will beat a rather stock SR. but if you run into one with cams and upgraded header with a larger turbo ect. ect. they can really be a serious runner. I think so far the most HP on a stock bottom ended SR is 540 some odd rear wheel hp. that is with nice cams and alot of other bolt on mods but the bottem end is stock. Not to mention the 9500 redline. But really. I guess it all comes down to.. the ole saying from Speeder.. " speed costs.... how fast do you want to spend"..
