Ok first I'm sure I have an 05 engine which I think is a Rev-up, but I have no way of telling because my car is an 03. Now I want to do MREV-2 and plenum spacer but not sure what to get or if I even should.

Please advise.

 

The 05 6MT had the rev-up motor. Why would your car have this engine?

Gcode, why would you think you have an rev up motor? One sure way to find out would be to pull into your local Infiniti stealership and ask them. The service manager s/b able to look up your engine numbers. If you don't have the rev up motor all you really need is the MotorDyne 5/16" spacer, MREV2 won't be necessary!

Check your cam covers.

^beat me to it

 

REVUP:

 

NON-REV:

 

well those pictures don't help engine is alreay installed, 03 engine when to oil consumption so I got an 05 engine since it was cheaper than an 03 engine.

I thought replacing the engine was common in these cars there were so many of them for sale when I got mine.

Uhh the link I posted and the other pics show exactly how to tell if you have a revup, all you have to do is pop your hood and look at the cam covers.....

IF you do have a revup, get the mrev2 and spacer. I'd you don't, just get the spacer.

You do have a 6MT, right?

 

Yeah I have a revup so I guess I have to spend more money, hopefully I get more horsepower than a nonrev.

Thanks for the help guys.
