Exhaust\Intake setup - needs some advise

AlWakRa

Hello everybody,

I am having some hard time deciding on what to do, made some searches and still the same.

First, my car has Fast Intentions TDX 12" res and FI non-res HFC.

I am planning to add more boltons and tune the car afterward. I have R2C air intakes in hand but not installed. Also, have Mine's air scoops.

What I was decided on is
Fast Intentions TDX & HFC
R2C Intakes
Motordyne M370
Tune

But as people are greedy I just thought of going a little different, I thought of going Z1 CAI, Z1 headers, and DE ART pipes.

My concerns are as follow

- Will R2C intakes + Air scoops have similar gains to CAI, I understand the issue with short rams is they take air from engine bay unlike CAI, but adding air scoop may solve the issue? because either way I will install the mine's but the placement will differ with either choice.

- Loudness, I like how loud the car currently, I don't want to increase this level marginally, when I was reading about Arts I found some mixed opinions about the sound level increase, however, the company and some opinions say it is quieter than any TP or HFC. If it is quieter than FI non-res HFC and I added shorties which shouldn't increase sound level that much, the result is same level of loudness this the conclusion I had, need somebody to chime in there, I know that I will gain a lot more HP/TQ over HFC setup. Or just add art pipes without headers?


The car isn't daily driver but I don't want to draw police attention when I take it on weekends, so let's say loudness under 3.5k rpm. Don't care if it's louder at WOT. I use the car on weekends and occasional road course track days.


or should I go all out with LTH and butterfly valves


Don't take me as I don't know what I want

Just to sum up,

Will R2C Intakes + air scoop be nearly the same as CAI + air scoop.

How different the loudness will be for Z1 headers + ART pipes and current catback compared to my current setup? Will the gains be noticeable?

How Motordyne IM complement the setup either way, or it will work better with one over the other?

I want to gain as much as possible NA while maintaining the same sound level while cruising. I would love to go turbo if it wasn't for track days.

go turbo

What about track days, will it be okay to go 15 minutes session without over heating in a climate of 30-40 Celsius. That is the thing keeping me away from turbo as much as I like the results with our engines.

is this a serious question ?

do you know how many turbo cars in the usa are tracked all day every weekend ?

Elmo370z

A guy i know is selling a BP V2 turbo kit for $4,500

Don't get me wrong, I am not in the states, I am from the opposite part of the world. I didn't find anybody successfully tracking his car here and we have very few garages that is good, leave alone being good with 370.

However, it wouldn't be a wrong idea to check other people cars, could you direct me to some? I made a lot of searches without success

Just to clear some misunderstanding, I am not looking for some fancy horsepower being NA, I am looking for something between 320-340 peak whp and 260-280 peak wtq (I know it depends on the dyno) and I know some parts will give better gain than the other, I made a lot of research to reach the conclusion above, I even searched for turboing the car and many suggested to have major cooling mod to the car and a conservative tune, cooling will not be the big problem, tuner is! I cannot be guinea pig for anybody here, and Sebastian from specialty z didn't recommend do online tune for TT cars and track them.

Please consider that the wealth of tuners and part availability isn't the same over here

Then, I have sound level issue locally, police use their ears to gauge the loudness I read a lot about ART pipes being a tad quieter than non-res HFC and the torque it gives is unreal, my current setup is perfect as far as loudness, I thought if I could squeeze some more hp and tq while maintaining same sound level when I am cruising, it will be a win/win case. A tad louder will not be a problem. Anyway, I found used HR ART pipes which I plan to buy them and see for myself how loud it will be.


The big issue here in Qatar, there is few modded Zs and Gs available to check them personally before doing anything, and this is why I am asking here as it is a great community.



madeinjapan Maybe you don't like the fact that I DD a charger

OP, you need to look into getting a new radiator, and the biggest oil cooler you can find. That'll make more of a difference tracking over there than bolt ons will.



How many factory Fi cars, or boosted Zs? Because the vast majority of boosted Zs never see the track. Mainly because of the heat. Kinda like the OP was asking about. It's almost like you don't read the question, and then put up yet another useless post. Don't give technical advice. New members might not know you're the single dumbest human being on this forum and listen to you. At least stick to the stuff you know, like surviving abortion attempts and sucking **** for money.

Yes, most of the boosted zs here are street cars. Is this news? We know you're a complete moron, but even you should have been able to figure that out. Is it asking too much for you to actually read some threads and learn something, or are there too many shopping carts out in the parking lot that need to be brought back into the store and you just don't have the time?

Thanks Chuck for feedback, I nearly believed he was serious

As far as mods, I have fast intentions 34 row oil cooler, Z1 SS brake and clutch line with RBF600, Project Mu B spec brake pads (which I tried them to see if I can get a dual use pads), whiteline swaybars with SPL endlinks, in addition to Fast intentions TDX and HFC and volks with michelins PSS.

I will have on order, Stillen brake ducts, Z1 sprinkle slotted rotors, later on I will buy Tein mono sport coilovers with active edfc and when the CSC dies I will install JWT clutch & flywheel combo with Zspeed CSC and new CMC.

As far as radiator, until now I see the OEM doing its job, maybe after going through all the previous I may need one. But I will see how it will holds before changing.


I got the exhaust because the car was quiet as sport car, and as I am going to tune, I want to have more boltons before going there. It's like I want to make a one time visit to the garage and tuner

Get an OBD scanner or water temp gauge, then. Switch to straight water and water wetter. Then see if the water temps are in line with what you should be seeing. The stock gauge isn't linear, and it's kinda hard to tell exactly how hot it's running. A vented hood would do wonders as well, especially since rain really isn't something you should be too worried about. Given your climate, if you plan on a lot of track time Z1's power steering cooler might need to be on your list as well.

At the end of the day, gears and a better diff would make you faster around the track than swapping out bolt ons.You can switch to TPs or headers, but you'll only pick up ~10whp over the HFCs you have and it's not a cheap move once you factor in labor.
