My 2005 Z Coupe Need Help
OP,
Here's my input from what I've read.
1. Intake/Intake Manifold - JWT Popcharger and as for intake manifold, people get good gains using a plenum spacer (search it for reviews).
2. Wheels/Tires - That's all personal taste and depends on your driving/environment
3. Coil System - Take a look HERE
4. K&N Air Filter??!?!?!?! - Just use the Popcharger listed above
5 Borla/Good Exhaust????????? - I'm digging the bang for the buck on the Invidia Gemini, but the HKS Hi-Power is popular too. There are tons of exhausts with sound clips on YouTube.
And really, just use the search function before posting... Every person that posts before search is just making the search function less valuable.

Thank you for the advice, im going to look into those, i was thinking about the pop charger so i didnt have to have the K&N air filter, it seems pointless to have to clean that thing so much.......... appreciate the advice. what have u done to yours?

I said I didnt need advice from you, I would much appreciate any advice from someone who actually cares about Z's....... You obviously do not, and as for you moderator, as you can see, he posted "sell that thing before you destroy it or w/e" I mean, i posted this for help on the 5 things I listed...
Did you see my post to your thread? Have you done any research? Or are you simply that lazy enough to just post up your questions and rely on us all to spoon feed you? I think someone needs to grow some thicker skin.
Was thinking about closing this thread, but now I have decided to let this one play out a little further.
Not much so far. I picked up the R2C intakes (the 07-08's have dual throttle bodies so different intakes are available) which don't need to be oiled. I put in a system (Pioneer 7" touchscreen, Soundstream 4 channel and mono amps, Dual 12's and Polk components). Blacked out the tails and rear signals. Shorty antenna.
Here's what I'm planning on getting
-Invidia Gemini exhaust, unless I can scoop up something else for a good price. -I may end up getting some rims and tires to use in the summer.
-Quaife LSD
My Z's a daily driver, so no plans to drop it or do anything overly crazy.

I didnt ask for anything special, i simply posted on the forum asking if anyone knew what good brands were on these upgrades i couldnt decide between them, and when I did read around, i saw this was general discussion in the forums, not "tech" questions because i am just getting GENERAL information on the vehicle, sure people have posted before me, i would hope so, why does that matter? a forum is here to talk, every Z can be modified different, i didnt see anyone else who had taken the same approach as i was first, so i started a new one, hope u didnt think i just created an account and posted the first thread i could :/ that was not the way i wanted it to seem.

Tpete how do u like the blacked out tail lights i cant decide, since im going with the white and black look, im thinking its going to be a requirement........ im still iffy about it though :/ What do u think of the CF hood idea?

yeah i read that, thank you for the link though I did not see the question and maze about the website forum chart, that is bad ***. I would hope u do not delete this because This guy has actually helped a lot, im looking at the JWT pop charger now, i need to see how that well work if i get the Kinetix Intake Manifold :/

Should bolt on in the normal way. I have JWT intakes for my HR

Thats what i was figuring, just wanted to make sure, thats the only thing thats going to suck getting this kinetix intake manifold is to make sure everyone still fits on it, it says same dimensions as stock, but you can never trust them.

general consensus is that its (kinetix) a waste of money unless you are going FI. Just go with a plenum spacer and call it a day.

It well save me about 400 bucks, I just have no idea what that Spacer is, i googled it and see it, im just worried about my stock intake manifold, i read that it was shitty, thats why i was told to upgrade it, then again i was reading a lot of re-search so i could be dead-wrong. does everyone have stock intake manifolds???????

Also im sure i can check on the exhaust sections, when did it start becoming ok to put single exhaust on 350zS? i always thought if it has duals u keep duals??? im un-sure why people go down to single? (not asking what brands or anything just why people are using single exhaust)

Q: What is a plenum?
A: On the 350z / G35, your plenum is the aluminum intake manifold that sits right in the upper middle of your engine bay. To locate it, find the air intake box, follow the tube to the throttle body, and you will see that the plenum is connected to the throttle body. The plenum consists of both the "upper plenum" which you can see plainly in your engine bay, and a "lower plenum" which is not visible in your engine bay. You cannot see it because your lower plenum sits beneath the "upper plenum". If you remove your upper plenum to install a spacer for example, you will see the "lower plenum," also known as a "lower collector". The lower plenum consists of 6 tubes or "runners" that guide the air from your plenum into each cylinder. They may not look that fancy, but in fact, the precise length of these tubes has a significant impact on horsepower and torque.
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. Increasing plenum volume typically has the effect of increasing horsepower. However, if you increase the volume too much, you will start to lose throttle response. Plenum design is a crucial aspect of engine design -- companies that make spacers are simply trying to get the most function out of the plenum.
Q: What is better, a plenum spacer, or a complete aftermarket plenum?
A: Some people swear by aftermarket plenums (i.e. crawford, kinetix), but for all intents and purposes, they accomplish the same exact thing as adding a spacer. So most people would tell you to choose whichever one is cheapest, which is usually the spacer.
Q: What is the difference between the REV-UP (300hp) and the NON-REVUP (287hp) Motor? Which one do I have?
A: Rev-up Motor has higher peak HP, lower peak torque, and a higher redline (7000RPM)
Non-rev-up Motor has lower peak HP, higher peak torque, and a lower redline (6600RPM)
Rev-Up Motor has variable Intake and Exhaust timing.
Non-Revup Motor ONLY has variable Intake timing.
You can tell which one you have by looking at your redline on your tachometer.
Q: What is a MREV, and MREV2? Which one do I need for my rev-up (300hp) or non-rev-up 287hp motor?
For 2003 - 2006 350Z's / G35's, Nissan has designed two different types of lower collector:
REV-UP lower collector from the 300hp motor = shorter runners which are tuned for lower peak torque, but higher peak horsepower.
NON-REV-UP lower collector from the 287hp motor = longer runners which are tuned for higher peak torque, but lower peak horsepower.
MREV = same exact thing as the non-rev-up lower collector, but Motordyne Enginering has given it a name.
MREV2 = Using the MREV as a starting material, this is a CUSTOM lower plenum that is sold by Motordyne Engineering. It has been precisely machined to remove aluminum from critical locations on the MREV. In other words, it is like a much improved version of the MREV which reduces restriction and improves HP / TQ.
If you have a non-revup motor (6600RPM redline), your best bang for your buck is to get the 5/16" spacer. The 5/16" spacer makes the most HP for the money. OR, you may choose to get the MREV2. By replacing your stock lower collector (MREV) with this better flowing version, you will make better "area under the curve" on the dyno in terms of HP gain. My opinion is that you should choose one or the other -- either MREV2 OR 5/16" spacer. If you get both, the HP gain will exhibit "diminishing returns", meaning you will spend a lot more money to make not much extra HP. So, usually the recommended option for the non-revup guys is to get the 5/16" spacer.
If you are a rev-up owner (7000RPM redline), you will basically only benefit from getting BOTH a 5/16" spacer and the MREV2. If you get the MREV2 only, your mid-range torque will increase but your maximum HP will drop off severely. If you only get the 5/16" spacer, you will not see a benefit. Several dynos have proven that for the rev-up motor, you basically need both the spacer and the MREV2, which will make a lot of midrange torque, without sacrificing too much peak HP.
For more information, search through the Intake Exhaust forum and read several old threads on the subject matter.
