I mean most of the parts excep internals and maybe fans have a purpose. The ignition stuff will help a bit considering the 350z is not a coil on pack ignition or a true one. New spark plugs.. well i'm gonna need those anyway and i'm not going one step colder. Bigger injectors just mean the injecturs are nto being used 100% which means longer life. The ARC stuff is just better cooling... needed if i want to push the car with drifting. The intake is just more power and so is the exhaust. I'm gonna need a new clutch soon and a 2.0 lsd will get me sideways and rasing the gear ratio will just give me a little more umphh but idk if i'm gonna change the final drive.

Internals are the only thing other than studs and gaskets that i'm not to sure will help and in what way will they help. Oh and I am gonna install it myself i'm not one of these guys who pays people to do stuff on their car. If i have the work space i'll do it myself except tuning.

A Z absolutely has "true" coil on plug ignition (I don't know how it could be described any other way). The individual coil sits on the individual spark plug...that is coil on plug. Stop listening to whomever told you otherwise

I understand what bigger injectors are for, as well as a bigger fuel pump (which you don't mention IIRC). What proof do you have that you need these? What NA threads have shown the stock fuel system to be inadequate? Again, don't do your build based on assumptions, it won't get you any more power or reliability. Base your choices based on need first, want second.

An intake leads to more power? Maybe on other cars, not on this one. It's for looks and sound, plain and simple. Remember, it's an NA car...short of majorly changing the plenum and intake tract, you are not going to alter all that much in the power department

I'll reiterate that it sounds like you need to do ALOT more research on stuff, vs just randomly picking cool sounding parts. I would suggest you pick your engine builder asap, and go over your plans with them, otherwise you are going to be throwing good money after bad with reckless abandon. There is nothing wrong with buying expensive parts for no other reason than you want them, but at the same time, it's important to understand what you are buying and what purpose it actually serves (vs what you just think to be true).

yes i don't know everything but why then when people have a stock car and dyno it and then do intake, exhaust, other basic mods and then dyno it on the same dyno do they get a gain of hp and tourque? like lets say your dyno reads 230whp stock and 215tq that afterwards they have like 280whp and 260tq? i'd really liek to know why those gains are seen

the gains are the exhaust, the tune, etc. The intake could be left stock and you would not see any meaningful change in the power on these cars

possibly true on the Z, not on the G... I know this is a Z forum, but lots of us Gs read these threads - so I thought Id throw that in here in case a noob G ends up reading...

A newbie anybody should not be reading this thread, there is so much mis-information in this thread its insane.

Z1 Performance

aside from fitting the larger intake tube from the Z to the G, what I said still holds true on a G as well

and amen to what kwame said

Unfortunately, that’s true in many of these threads… there’s boatloads of good info, but you have to sift through a lot of BS to find it.

Whats worse is the “internet experienced” people that perpetuate some of the crapolla because they read it somewhere (but never tried it in real life)…

I guess it’s the nature of the beast.

testify! lolol


all too often the "my friend told me" wins out over "I've done it and here is what I found"....you can only lead the horse to water though.

thats what I'm referring to... and I don’t think its larger - however it does omit the baffling and has shown improvement.

Usually, when people post a specific build list, they are looking for helpful, constructive criticism. This time it appears that the OP knows what parts he wants to use and was posting his list as an item of record.

Seems like the only thing for us to do is wait and see how it comes out.

just like a polished upper plenum doesn't lead to any meaniful gains, a reason i'm opting out of spending 100hrs polishing it to a mirror finish, lol!

saying that, i do understand slightly improved parts do actually add up to something. how much is usually the subjective part depending on dyno.

i personally feel my current intake system is better than stock(including paper filter). the improved physical dynamics makes it so... even if its +1hp, lol.

Performance = sum of the right parts (some parts might have minimal to no gains by themselves, but in conjunction with others show good results)...

BTW, polishing upper plenum (I presume you mean inside) probably doesn’t warrant the amount of hours... but taking down the casting flash/burrs in flow areas is worthwhile. Also, machining critical flow points in the lower collector have shown good results. But this is stuff most of you already know.

All the little things combined with more substantial mods do make a difference.

Zquicksilver

iTrader: (5)

agreed... but short of trimming some flash/burrs with the grinder and dremel; i don't feel hours of "polishing", as i've seen performed by others, will warrant any "meaniful" power.

and though words may not read "tone", you both have a valid point as i mention in my post.

lol... i'm really looking for critisism but sometimes if you just listen to people you arent' always getting the truth so i like to argue a bit to see what comes out and what's real and not

i know the z is well built and most of the mods don't do that much more than what stock already does. I am glad to know that an exhaust and tune are the main if that small increase of power. As for the coil on plug I heard that the 03 350z was a coil on plug but the best was a coil on pack which is what the newer z's are... idk if this is true. Is it worth it to do ignition and grounding and voltage? I know a radiator and oil cooler will help even if all it does is keep the car a bit cooler.

Honestly when i look at the amount of time, $$$, and effort put into a na build and then i look at a turbo i feel like a turbo is the best way to go if i only want to spend 10k on performance. I know i'm gonna drop a good 10-15k on suspension so i dont' want to get oo pricy with performance (tac weld chassis, full roll cage, fully adjustable suspension, camber, toe, ect..)

All I know is when I look at your parts list... I can just picture a whole bunch of little Japanese guys in clean jumpsuits in the marketing departments of the aftermarket companies that you have within your list high-fiving each other and simultaneously bowing at one another for hours on end.

Zquicksilver

iTrader: (5)

^ your imagination is rather creative... lol! but why do they have to be little Japanese guys, can't a big fat Japanese guy get a job too! bbwhahaah!

speaking of cooling mods, since your planning on installing a roll cage (track), i would opt for it all...
-A good vented hood
-Nismo thermostat
-Rear Cylinder Coolant Bypass Modification
-Large aluminum radiator
-Oil and power steering coolers
-Vented diff cover
-Silicone hoses
-High quality synthetic oils in motor, trans and diff

on it's own you are probably right, but doing so with the aid of a flow bench and manometer (sorta specialist tools I realize) pays big dividends. Doing it any other way is sorta guessing, at best.

they are still high fiving from you and I lolololol

Thats because obesity is more so an American thing.

Tell me about it, my bank account NEVER recovered, lol.

The only difference is we knew not to expect any real benefit from the crap we bought. We bought them mostly because we thought we were cool buying things which had descriptions that had to be translated for us through babelfish.
