I think Im going to get headers then Tune it.. I want headers and I don't want to have to retune it.

I will post before and afters of both for some of the NA guys here.

 

Waste of $$$ but its your $$$

 

i havent even seen any dynos showing headers make any more power on a blower either. you need cams to make that power.

 

X2.. Trust this guy he knows his sh*t... :P

 

+1

even if I got a set of headers for free, it isn't worth installing them.

 

+1. ive ran rich before and my dyno results were crap...

 

Damn, I am really reconsidering the headers, I told nexx I would buy them from him too..

 

Just a thought do u plan on going FI any time in the future? If so i would just save my money and get a nice turbo kit. That what i did. I dyno my car stock and after i turboed it. I have a 05 touring, stock with just the jwt intake which i bought it with made 246hp at the wheels on MRC dyno, I just waited till i could get a tt kit and now im making over 400hp. Your best bet i think if you want to add something would be a piggyback or stand alone like some of the other people are saying, this way if you plan on going FI later on it can still be used. Correct me if im wrong guys.

 

FI.. Not really, as much as I would love to. I just don't have the funds because college is eating the majority of my spending money..

I have thought about it multiple times but I can't unless I quit college, no thanks :P

I was thinking TS reflash as well, that and a UR pulley could get me to the 250.

 

Speaking from experience, N/A bolt ons are a waste.

I had it all
-TS reflash
-UR pulley -> which I would NEVER run again due to crank issues
-Intake
-Plenum
-headers
-test pipes
-exhaust

I pulled 256 whp DJ with that. All that for about 20 hp... HUGE waste of time and money.

If you are in college save your cash on those garbage parts. If you want to stay N/A and you MUST do something; spend money on suspension, wheels/tires, lightened clutch/flywheel, and 3.7 or 3.9 final drive. Money spent elsewhere is money pissed away

 

Maybe I should just be happy to dyno higher than stock sti, evos, and srt-4s here. I was also thinking about just starting to do looks on my car.. CF lip kit maybe..

 

+1. from what I've been reading to make headers worth the money you have to pair them with cams and higher compression pistons. and the cams have to match up with hte headers. making N/A power is a nightmare....arent many guys that have figured it out. do the cheap stuff; test pipes/spacer/gears, and leave it at that unless you want to make a crazy high-revving N/A engine like Z1's for a small fortune.

 

Dont be sad man, I had Testpipes, popcharger, 5/16 spacer, UR pulley and nismo exhaust and put down 240 whp and 217 TQ on a dynojet....then again mine is auto

 

Yea I hear ya. I did actually have a decent amount of TQ though.. seemed pretty high.

 

i wish walkert would chime in with his before and after dyno after his topspeed header install. just install with no tune he gained almost 20whp between 3500 to 5500rpm. he showed me the overlay of the two dyno runs and i was kinda shocked. i would call that significant. just depends on how much you are paying for everything. $500 headers + $500 install is pretty high. pay $300 for a good set of headers and diy install is great bang for the buck improvement, imho.

 

I had topspeed headers (AKA DC headers, alphawerks, etc) I paid under 300 for them, self installed them and they were a complete waste. Even with a free set of headers I wouldn't go through the couple hrs worth of install time to put them on.

 

The Z's seem to be odd like that; I have a friend with a 3.5 Maxima (he works here too, actually), put down 250/244 with just intake, headers, 3" exhaust, and lightweight flywheel through a 6MT. Granted, RWD has more drivetrain loss, but still.

Needs a tune, then we'll see what it puts out.

 

I had a bunch of NA mods before I went with the turbo kit and it was pretty much a waste of my time and money as well. It was pretty much everything Zivman had besides the reflash.

Headers are too big of a hassle and don't really make much power to be worth it. Tune the car. You will make more power than any bolt on will give you at this point. I would go with a UTEC and skip out on any sort of reflash.

I find it amazing that people still buy them with ALL of the negative experiences voiced on these forums. I guess some people just have to learn the hard way.

 

Ya but I changed my mind lol. Now I am going to get something exterior or interior.

 

The only headers that seem to make decent power consistently are true long-tube headers and the Crawford units...either one those you want to have installed...believe me. Some would rather pull the motor than install them with the motor in the car.
