Just bought an 04 350z modded

[csramotorsports]

I got it from an auction, greddy exhaust, axis rims,coilover suspension, Injen Cold air intake...I was reading that the 05+ rev up motors have a "REV" on the gauge cluster, well my Tachometer has a "REV" on it? Am I suppose to have this or was this only for 05+

[bryan d.]

are you talking about the little red light which you can set to flash at a certain rpm? cuz my 03 has it

[Harman850T5]

to my knowledge all 6mt Zs have this feature. My 03 has it too.

All 350s with the 6MT have the rev light. The RevUp is a motor variant of the regular VQ35DE, that's all.

...and welcome to the club.

Hey guys, Okay, so my car has the Greddy titanium exhaust system, and I can also see that it has headers, I can't tell what brand the headers are. All 4 o2 sensors are hooked up, the car is cat-less, headers straight to greddy exhaust. The car has the "service engine" light on, codes are for air/fuel sensor. Do these cars run in limp mode? I went to the dealership and he said it won't cause any issues because " these cars don't have a fail safe"... anyways, is there any cheap way I can fix this? or should I just leave it be??

Your service light is on probably due to being catless. I have test pipes and it shows up in my car as well.

The software from Uprev known as Osiris can allow you to disengage the light if it distracts you.

Ya that's what I figured. Thank you
