FX35 MREV2 + Spacer questions

    Is there a reason why the MREV2 is positioned with the 5/16th spacer in mind? What I'm really wanting to know is if the MRev2 will work with my 1/2" spacer. I dont want to have to get the 5/16th and go thru the hassles of selling the 1/2" one.

    The only thing I can think of is that the MREV2 is designed for REVUP engines and they can only fit the 5/16ths spacer. Any ideas?:dontknow:

    Haha, I seriously cannot find anything. I don't know why they wouldn't be compatible. It's also "not worth it" if you're trying it on a non rev-up... but I can't find out why?

    My searching is broken :shame:

    But I do know that there's a guy selling fake MREV2's by the name "RebelinRI" and he was 'busted' by Tony @ MD.

    But forrealz I can't answer your question and I can't even find an answer to your question.

    Yeah beware of fakeys showing up on forums.

    The org has a good thread on the mrev2 thingy, some g tech runs were included in the info.

    Thanks Cube - I did a search on 350Z & Myg35 also.....and I did see the guy selling the fakes also, thanks for the heads up.

    Yeah I saw that - the one by Geo right?

    Yep Geo was the tester. I have this thing but I'm not sure if it did anything. My butt dyno is the worse to be honest.

    I think from the org, testing showed he picked up around .2 in a 0-60 test. the MREV2 is supposed to give very good midrange gains, with peak power only being a few horsepower higher.

    it was designed for the REVUP engine, but im pretty sure it will work well for us. and hey its not even that expensive because after you get the core exchange it comes out to around $150 or something...one of the cheapest mods. i am highly considering this mod as well

    It's a 100.00 core exchange if you have a non-rev up lower collector to send back to them. This core exchange has been going down lower and lower, you end up needing to spend 350 or so for this mod.

    OH damn! i thought the core exchange was closer to $200? :confused: that makes it kinda expensive then lol

    Will, i think theres an MREV2 for sale on the org...and i think i saw one for sale on g35driver too but im not sure.

    I saw the one on the Org, but the guys only got 14 posts or something like that- I dont trust him :err:

    I saw a couple on my350Z but im afraid of the fake ones floating around. I dont know how to spot a fake either

    The MRV2 will work with a 1/2" spacer or a 5/16th". I asked Tony C. which one he recommended for us and he recommended the 5/16. It's a tradeoff between torque and HP. The 5/16 makes better torque but slightly less HPmax. Overall though the 5/16 makes more total power than the 1/2".

    In case this makes any sense, when you look at Motordyne's dyno charts you'll see there's more area under the 5/16" curve than the 1/2" curve. Even though the height of the 1/2" curve is greater. Area under the curve equals total power so more area under the curve means more power despite the fact that the 1/2" makes more absolute power at peak. .

    I've given up trying to judge based on my butt dyno. There were some charts Tony C. posted that showed specifically what gains to expect on a Non revup engine specifically from the MRV2 ** even with a spacer installed **. They were there.

    Not sure I can explain this easily. You're first mod, either the MRV2 or the spacer, will give you the most gains. Installing either the MRV2 after the spacer or the spacer after the MRV2 will give you incrementally less gains. But still gains none the less. What I'm trying to describe is sometimes referred ot as the law of diminishing returns.

    I don't know. There's something about Tony C at Motordyne I trust. His stuff just seems to work and he stands by his product.

    These are two pretty good threads for mrev2 & non-revup motor.. In the first one, the ECU retards his timing when running mrev2+spacer so dyno charts are a bit problematic but the mrev2 alone dyno is pretty promising.. These are the same dyno sheets on motordyne's website as well.. In the second one he gets tuned..
