Headers or Intake or Both?
MREV 2 Manifold TM - The undisputed king of bolt on power.
A universal manifold modification for use on any VQ35-DE engine. When used with or without a spacer or aftermarket upper plenum, this lower plenum will make substantial power gains.
Multiple independent test show when used with a 5/16" spacer on the revup engine, the combination will add a "minimum" of 15+ HP and 18+ TQ in the upper midrange. Many independent MREV 2 Manifold REVUP tests have dynod in excess of 20HP and 30 TQ in the upper midrange and with high RPM peak power increased by 3-5 HP.
The MREV2 is a prerequisite to the plenum spacer when used on a revup engine. No other normally aspirated VQ modification provides as much gain as the MREV 2 Manifold!
so woops, maybe 20 hp

We all know MD products will give u legit gains but not as much as advertised just like anything out there. IMO final drive is the most underrated mod out there and not a lot of people look into that.
If u look all the mods out there for the G, you will be lucky if you get half of the power that they advertise on their website including MD products.
Nothing beats the real life personal testing of mods.

The only way that is possible in similar weather conditions is if they tune the car after putting the mod on to gain 20 hp anywhere in the rev range.
I don't doubt there are cars able to make the gains they claim, but those motors are definitely not stock... but I wouldn't be surprised if the dyno they used to get these numbers read high either...
More realistically, you'll see about 15 lbs of torque and 1-2 hp gains on a revup motor, not too sure about non-revups.

where? Post or link? Consistently = more than 1 or 2 different dynos/cars.
OK, you got me... I lied... $600 for Motordyne MREV2 and spacer w/ copper iso thermal is going to make you 15-20 hp and 18-30 tq. I was just trying to keep this secret mod to myself... and intakes add 5-10hp, and stickers add 3-5.
I wasn't trying to be a d!ck, it was an honest question. Maybe someone can enlighten me.
Can't find it either.
I want to say he may have mentioned it with the 100 ques I had for him when I was installing my MREV2, but don't want to put words in his mouth.
If your 6mt for a little over $1500 I would get MREV2, 5/16 spacer and 4.08 or 3.9 FD gears if your staying N/A. The MD products you can install yourself, but the gears I would have a shop do it for you.

Most people seem pretty skeptical about the mrev2 and spacers. Should i just go for the sound beneft of headers and forget the manifold? If they dont add the much power is it worth it?
most people are not skeptical about the mrev2 + spacer.. the point is not to expect HUGE gains, the mods have to build up as in they work best in combination with others
Read this thread again biglit2000.
If your V35 G is 05+ 6mt (revup motor), then the MREV2 with spacer is going to be the best bang for the buck. Otherwise, just get the spacer without the MREV2.
Technically, they could have just taken a car with tons of bolt ons without any tuning, added the MREV2 and spacer, tuned and then added up all the additional power to get those numbers. But you will never see gains like that with the MREV2 and spacer alone...
