What is the typical torque and hp between 2500-3500rpm in a stock 2000 XE V6? Does anyone have a torque curve? www.Nissan-USA.com doesnot show that anymore.
I wanted to compare that with SLRs 2500-3500RPM
after mods been done? Their torque varies between 226-234 in the 2800-3400RPM range..

I know that the VG33E n 2000-2002 Xterras gets 200 lb.ft. of torque at 2800 RPM. It gets 90% of that (about 180 lb.ft.) as low as 1800 RPM, I believe. 200 lb.ft. is the maximum torque on the Xterra, so I guess it's all level (or downhill) from there.

I have the curves on my webspace:

I also chassis dyno'd my truck back in July and verified the curves. For the range you were looking atm the toque is relatively steady at about 170 lb-ft to the wheels, and the horsepower builds from about 75 to 100 at the wheels.

Here's a pic of my dyno sheet:
