it took me 4 daym hours to install this..the hardest part of the install is getting the hoses off the upper plenum and reinstalling the strut bar...but everything else is pretty easy..hopefully the bolts won't get loose..i followed all the instruction and the torque sequence..everything was bolted 100 inch pound..should i be worried of anything? hopefully there's no leak..it sounds fine when i started it and droved the car...
this two mods you can really tell the power added..it pulls harder in my oppinion..hopefully it will lessen my quarter mile
anybody here with this mods lowered there quarter mile? if so how much?

 

sounds good, how much did all the parts run you?

 

I just did this same install, my car pulls much harder, and it seems to have a rougher vibration in the throttle at low speeds, ( 5-10 mph). Other then that my install took me abut 2 hours and the part i found difficult was the white spacers on the inside of the top plenum, they all fit too loose and would fall of if not held down with screws. I think ill probably reset the ECU to see if i can smooth out the low rpms a little bit. Mine MREV2 and spacer cost me $711.

 

i don't know the cost of the part..my girlfriend gave it to me as a gift..=) as for the white spacer in the plenum it fitted so nice and tight..it didn't even fall off, just stuck through there...my idle is smooth just like the stock..no vibration at all, so i guess i got lucky..
Abishop: you probably touch the trottle body's butterfly, that's why it's rough on your idle...you just need to reset the ECU using that instructions they give you and hopefully it'll be fine..
so did anyone lowered there quarter mile time with this mods?

 

Well i have not reset the ecu yet, but i know for a fact i didn't hit the butterfly in the throttle body, strange, i guess it wont hurt to reset the ecu.

 

Where did u guys get this combo from?

 

bahraini, u can get it directly from MD's website, its the best place to get it from... not necessarily cost wise though, but their shippment times r very accurate and quick!

 

I did mine a week ago and I love it. It took me about almost a good 5 hours though.

 

Maybe your strut bar is rubbing against the top of the plenum. I don't know if that's actually it, but you might want to check. Make sure there is at least 2mm of space between the bar and the plenum. I had a strange vibration when I installed mine and I found that to be the problem.

 

For the 6 bolts in the middle of the upper plenum, I think they should be torqued to only 80 inch lbs. I don't think it's that big of a deal, but I have heard it may cause problems.

 

if your strut bar rubbing the plenum . you could adjust by tighten the bolts on the bar .

 

Corect me if I'm wrong. The MREV2 is designed for the revup engines only? Does it need some modifications for it to fit a non-revup engine?

Thanks

 

i tried about 10 times to reset my ecu.....it wouldnt work for me

 

Disconnect battery, pump break for like 20 times, that should reset ecu.

 

I installed the combo last weekend (5/15 spacer, MREV2) on top of my JWT Pop charger that I had installed a few weeks back in my 06 Z.

The biggest difference is definitely in the mid range. If I floor it at about 3.5-4k in first gear the rear tires will now break loose. I also like the difference in sound which is amplified by the pop charger. It has a more agressive sound in the higher rev range.

One thing I noted though is that the car doesn't like to rev as much as it had with the former manifold. It seems to take a bit of time to reach 7k RPM so I now end up short shifting at 6.5k. I'm wondering if the slower reving would actually hurt my 1/4 mile time?

 

i installed my mrev, and spacer on my z 5k miles ago, but i never reset the ecu. would resetting it now do anything? anybody?

 

No it wouldn't, coz the ECU has already adapted to your new setup. You only reset it when you first install it so the ECU goes to the base map and adapts quicker

Anyways, has anyone installed this combo on a 287hp engine? What mods needed or was it a direct fit?

 

It is a direct fit.... but the mod is designed only for the rev up engine...

 

Thanks, as I understood, It would lean up the A/F dramaticly so with no reflash it would be usless

 

I wouldn't say it leans out the NON-REVUP dramatically, but it does make it run leaner from what ever the baseline is.

If you have dynod your Z and found the A/F ratio to be at or below 13.0, you can install both. If its above 13, just do one or the other (spacer or MREV2).

OTOH the REVUP ECU adapts much more readily to flow modifications so it takes to the combination very well.
