as many of you know I have a 2005 altima 2.5 and was just wondering if anyone knew the hp rating I believe they are claiming 165 or is it 175? but everyone knows that's not what your getting at the wheels so I was just wondering if anyone has had a dyno done or anything like that I couldn't find any dynos on youtube but eh I am saving up for stage 2 cams and I am going to have TD performance do that cam job (I don't like messing with timing I always seem to mess it up lol) and after the install I was going to have them dyno it so we'll see after the cams I think i'm pretty much out of N/A options so I think that's going to put an end to the ol performance upgrades for her time to get some damn rims haha

Stock, you should make something in the 140 range, depending on your transmission. Cams and good tuning might bump you to the 160 range, which is what the revised QR in the new Spec-V should produce to the wheels (200 crank rating).

cool cool so I'm probably seeing around 150-155 with header CAI and it being 2.5in from the header allllllll the way back to the magnaflow muffler no cats no resegnator just a bunch of welded pipes for no emissions in Ohio I just need to get those cams in and get her on the dyno and it's an auto unfortunatley I was looking and the only place that I can find stage 2 cams is Jim Wolf does anyone know of anywhere else that sells them? I would like to get her in the 180s range but I don't think that is going to happen without putting the baby on the bottle

Nismo QR25 cams are not that expensive, compared to other engine applications (VQ cams cost twice as much).
