Can i reset the ECU by disconnecting the battery for an hour or so ?

 

I have an 08 XS. Im trying to figure out what kind of mods i can make with my G. Would a spacer or mrev work for my car?

 

Yeah, bump on the 08 x. Will these work on the gen 2 '07/'08 x sedan models?

 

No. The spacers are only for the engines with a single intake.

Dual intake engines are not compatible.

 

Thanks,

After researching a little bit, I think our engines were designed optimally in that aspect.

 

so having a CAI and a motordyne 5/16 spacer is not a good combo or what? i'm confused either i miss something or i'm just not reading this tread right help me out

 

The spacer works but skip the CAI. CAI's don't do much on this engine.

 

My most recent engine mods were the 5/16 spacer and MREV2. And I must say I was a bit of a skeptic but these are one of the best mods I did. Car pulls very nicely.

These go well w/ my K&N filter, Ztube, and Motordyne Exhaust. What I need next is the ART pipes and Tune.

 

Figured I'd add my $.02. I just installed the MREV2 and 5/16" copper iso spacer this past weekend. The install was easy, the instructions were a breeze to follow, and the gains are definitely noticeable. Seriously, starting at ~3500rpm the engine starts screaming, in a good way. Not only that, but the note of the car changed as well.

I'm completely happy with this mod. The combo is a must for all 6MT owners.

 

What is the recommended place to buy these two from?

I have a Z-tube, JWT popcharger, and Magnaflow exhaust but that's it so far and I'd like to do a couple more things like the MREV2 and spacer to "complete the circle".

 

does the ztube causes your G to lose torque too? or do they improve/same

 

I didn't really feel any performance differences one way or the other when I took the stock airbox out. It's really more of an audible thing for most people I'm pretty sure. It definitely sounds a lot more aggressive.

I do get just under 2mpg better gas mileage now (exhaust upgrade included in that) than I did with the stock setup. Been using an app called Road Trip to track each fill up for the past 3 years or so and my MPG has been remarkably consistent in my G.

 

Interesting mods, Mrev2 and 5/16th spacer...which comes out to about $600-700 for max of 13-14 hp gains...is it worth it? and how does a lightweight pulley play into this.
Thank you!

 

Hey guys, im new to this site. i just got my G35 coupe and i really want to mod it. what you think of Stillen Z-Tube intake, and 3/8 iso thermal spacer or 5/16 ? what do best ?

 

Just installed mrev2 and 5/16 copper spacer. Install went very smooth, but my intake has a bit of a "wheezing" sound now. It kinda sounds like a BOV. You can hear it when rev'ing quickly or when driving (it's a high pitch whistling when accellerating). I have no SES light and my test drive rip was great - more power pulling right to redline.

I don't have any air leaks anywhere. All hoses and everything are sealed up. The noise is distinctly coming from the airbox - which was never touched during the install.

I installed my z-tube a month earlier and didn't have this "wheezing" issue... why is it happenning after my mrev2/spacer install?

The only thing I can think of is maybe a ECU resent and idle re-learn so it can adjust to it's new found air flow? Or I just try reinstalling the intake again
