I was just buying the 5/8" spacer for my non-revup engine and I came across the mrev2. It says it increases HP more and is more money.

Should I just go for the Mrev2 .. is it worth it???

 

we just had this debate...and in my opinion, it's not worth the money... i wanted to feel the additional TQ from the lower plenum of the AT, but did not... others state they're completely satisfied... maybe it's in their head...maybe they're right... either way, it's a crap-shoot, IMO...

 

so its better just to stick with the 5/8" spacer?

 

i own a '04 g35c 6mt and also had the same debate and picked the mrev2 without spacer. for me closer to stock and got good deal on it - conceptz performance. if i can get any kind of core refund it will be cheaper than spacer.

 

i think you mean 5/16", and yes...that will add the HP... the lower plenum from the AT (MREV) will add the TQ... you MAY feel the TQ, but it's doubtful that you'll feel the HP from the spacer... adding 10HP at the top of the powerband is not a noticeable difference as far as feel... actually, the only benefit i've noticed outside of a bit of TQ after 4500 is better MPG... i have noticed an increase in that... but ROI (return on investment) will be a long time coming just from the few MPG gain...

don't let me discourage you...you may have great results from the MREV... i would just NOT expect it to be very noticeable as far as pull or speed increase goes...

 

i agree... coz at concept z performance is a great guy to deal with... if you pick up the MREV, get it from him...

 

The MREV2 is made for the Rev up motor on 05's and 06's.

 

The MREV2 is a new product from Motordyne Engineering. It's a new design that works on both the REV-Up and Standard VQ35 engines.

The average power gains on a 260 or 280hp motor (non-rev-up) are better than the 5/16" spacer. This modification increases power across a very wide rpm range. The MREV2 should be used without a spacer on the standard engine, unless fuel/ECU modifications have been performed as it may cause the engine to run lean.

The power gains on a 298hp REV-Up motor are similar to the earlier MREV kits, when used with a 5/16" spacer kit. The 5/16" Spacer is recommended for the REV-Up engines as it will help safely increase power, when used with the MREV2 collector. This setup averages 15+hp and 18+ft.lbs in the upper midrange (approx 4500-5000rpms). Many independent tests have shown even higher gains as well!

 

so 5/16 spacer, mrev2, 1/2 spacer ... or are none of these worth it ???. I ready alot about the spacers and I thought they were definately worth it.

 

The MREV2 was designed w/ the 05 and 06 in mind. Personally, I would not spend the extra money for a non Rev-up motor. I would just go w/ a spacer unless I had excess disposable income.

 

Do you feel any difference with the MREV2 and 5/16 spacer? Also, has your MPG changed? Was it worth the money?

 

you think so? huh. I thought it gave the 03 and 04 good numbers

 

I have heard that the MREV2 will increase performance for non-Rev up engines. However, it was designed specifically to resolve some sacrifices made when the 04 280 hp motors were increased to 298 hp. Do a search for Tony's (he posts under the handle Hydrazine) for a full explanation.

Although specifically designed for the Rev ups, Tony claims that non-Rev ups will also benefit. I wouldn't put it on a non-rev up, but it is definately worth the $446 for my car .

I guess the bottom line for me (if I had an 04) would be how many miles I had. If I had 10k, then it might be worth it. For 60k, I would just put in a z-tube and pop charger, save my money and enjoy the car for what it was.

 

The gains for the MREV2 on the non rev up motor are noticable however, if you combine that with an after market plenum or spacer on the non rev up you risk leaning out your fuel, but if u reflash or piggy back a Slip Second A/F ecu on ur car you'll definately notice a huge difference.

 

So if i were to get the MREV (is there a 1 or just the 2) and a iso thermal plus a .5" spacer, i would have to get a piggy back or a reflash? what kind of added performance would i be looking at? and where could i buy this package at?
