I guess the 'best' and most expensive go hand-in-hand. That would probably fall upon Crawford's headers.

A lot of the others are similar designed off of one another... Nismo, Strup, Alphaworks, DC, Topspeed, etc. though there is a lot of speculation of which is better than the other, etc.

i might just get the dvd player that they're talking about in the audio forum.......
i'm still not sure what the spacers are and what they do.... and what brand i need to get? i don't have a high rev engine, so from what i gather, there's no point in getting a mrev..........

Spacer increased the area in the intake manifold. You can get the Motordyne or AAM, both are basically the same.

And from what I've read, the MREV-2 lower plenum does very well for the non-revups as well, along with their plenum spacer.

If you're looking for a couple of N/A mods that will do something for ya, just get a popcharger, plenum spacer, and test pipes. Stop there and you'll be just fine. You'll be happy with the money you've spent and the gains you'll get.

From the top 100 questions, wouldn't hurt to read it:

Originally Posted by Wired 24/7
Q: What is a plenum?
A: A plenum is the cavity that sits between your throttle body and your engine. It can be identified as the large aluminum mass sitting right in the middle of your engine bay. The "lower plenum" which is not normally visible in your engine bay sits below the "upper plenum", which you CAN see. The lower plenum consists of 6 "runners" or tubes that guide the air from your plenum into each cylinder.

Q: What is a plenum spacer?
A: Several companies make a "spacer" which rests between your lower plenum and upper plenum, to increase plenum volume and reduce restriction from within the plenum. For example, Motordyne engineering's 5/16" spacer, or AAM's angled spacer.

Q: What is the difference between MREV, MREV+, MREV2? Which one do I need for my rev-up or 287hp motor?
These are all code words for lower plenums. If you have a rev-up motor (your redline from the factory is 7000RPM) then you have a unique lower plenum with shorter runners. If you have the 287hp motor (your redline from the factory is 6600rpm), your car is ALREADY EQUIPPED with the "MREV".

The rev-up motor is well known for having less midrange torque than the 287hp motor, while its overall horsepower rating is higher (300hp).

If you have a rev-up motor, you can choose to swap your lower plenum for either MREV, MREV+, or MREV2 (available from Motordyne engineering).

The MREV is equivalent to the factory lower plenum from the 287hp motor. Installing the MREV in a rev-up motor will increase torque through the midrange but lower peak horsepower.

For an additional fee, the MREV+ and MREV2 are available as well. The MREV+ has a bit of metal shaved off of the two runners at the front of the engine. This reduces restriction inside the plenum and is reported to give you a little bit better horsepower.

The MREV2 is similar to the MREV+, only it has lots of metal from the lower plenum grinded and shaved off. More of this metal grinded off yields less restriction (for a higher price) and more horsepower.

If you are a rev-up owner, you will most likely benefit the most from getting both a 5/16" spacer and the MREV2. If you are a 287hp owner, great gains have been shown from installing only the MREV2 with no spacer.

For more information, search through the Intake Exhaust forum and read several old threads on the subject matter.

You do not need an MREV, just a spacer.

Motodyne spacer is gonna be the best bang for the buck ( aside from notrious)
Also if install is free, you might want to look at 3.91 final drive.

And if you take it one step further, a good aftermarket exhaust will work very well with the test pipes. But don't bother with the exhaust unless you first have the test pipes. An exhaust by itself will make gains but test pipes will make more power for much less money.

You can skip the exhaust, but you can't skip the test pipes.

And if you have a REVUP, the MREV/spacer combo is pretty much mandatory.

If you do the MREV2, spacer and test pipes you will gain the majority of what can be made on a modest budget.

There is still more to be made in other areas, but it gets much more expensive fast. And most of them will require professional assistance for installation or tuning.

A 3.9 final drive is very cool too, but its not a home install job.

QTP exhaust cutouts $300, muffler shop install $100. More power than any catback.

Most bang for your buck mod is improving your driving skills. Take it to the track, bring a helmet, and do some hpde runs. You will be surprised how fast a stock z can go. But my 2nd option will be the 3.9 FD only if u are na.

Q: how will the stock exhaust sound with test pipes along with pop charger and plenum spacer, any rasp?

depends on your test pipes and exhaust. Nothing to do with an intake or plenum spacer. Resonated test pipes reduce rasp. I had test pipes with the Borla True Dual and had no rasp at all. Changed the Borla to the Stillen True Dual and have more rasp than a 90yr old smoker. Well, when accelerating hard. Normal driving conditions, you would never know I had any mods at all.
