Ok guys I'm in a pickle here and quite frankly confused at the information im reading. I know this has been discussed before but of the 8 pages of posts that came up in my search I'm reading mixed info. I initially found out ONLY the 35AE with 6MT Z's from 2005+ had the RevUp but then later in my search I also read it was not only 35AE but ALL 6MTs that had it and the 5ATs had non-RevUp. Mine is a 2005 roadster manufactured in 10/04 with the 6MT so I'm trying to figure out which is correct... RevUp or non-RevUp since from my research on here that will determine whether or not I'll need a plenum spacer (I read it'll produce gains for Non-RevUp but not so much for RevUp). Can someone tell me which side of the spectrum is the correct one so I can add the spacer to my list of first mods if need be? Thanks, and sorry if its been covered...I'm simply confused

Mods you can delete this...when i searched once i got home i found more pages saying the non-revup...guess my phone only like to like the first a few :/ non-revup and plenum spacer for me!

You could just look at the RPM gauge too. If the redline starts at 6600 then it's an 03-05 engine, if it starts at 7000 then it's the revup, if it starts at 7500 it's the HR.

hey that's much easier to understand for us noobs than all the technical discussion!! really no gray area there. 6600 is my magic RPM lol
