5th gear at 70 mph is 3150 for me. I think sr20de's love the rev. plus that's when the real power kicks in.

The auto runs about 500 rpm's less than a similar 5 speed. Larry McCloud in his stock with pop 200sx vs my totaly stock auto was 500 different. At ~71-72 on my speedo Im running about ~2750 or there abouts, its under 3k. I always keep it below 3k while cruiseing for max gas mileage.
These SR20DEs love to be run high and when a clutch job is needed (I love my ACT) save for a JWT aluminium fly wheel!!! It makes a world of differance. I'm not sure what my RPMs are at cruise as my cruise speed is a little high. I'll check it out. If you are worried about gas $$$ then she's ok at low RPM. Some engines hate low reves (like older bimmers), but Nissans don't mind.
I didnt say i didnt rev it. Actualy every time I drive it, atleast once a day when I am out, I red line it jsut to keep from sludging up. Just when you are on the highway crusing, why would you be reving high. Like saying I cruse at 70 in 4th, because the engine likes to rev.
