well im at a holding point and just debating on wether or not to upgrade my header'

my current set-up yielded 190whp, 130tq on a jdm itr header, a local is selling a profab header at a good price how-ever im debating on wether or not it would be worth it to upgrade'. my tuner said with a better flowing header i would make over 200whp', i guess the question is, can you feel a good difference with just a 10whp change? Id probably have to have it tuned again or at least some minor adjustments to gain a power difference which is going to lead to spending more money'

ive always wanted to break 200whp while being na without touching the head or bottom end but at the same time if the power difference isnt going to outweigh the total price and hassle than i may just hold off, just looking for your opinions', i guess its going to come down to pricing on the header and how much a retune on the dyno is going to set me back as well as if the power difference is really going to be noticible and/or worth it'

current set-up...just off the top of my head is

00 jdm itr motor
j's intake
jdm itr header
greddy exhaust piping, e cut out, kteller resonator, tanabe muffler
skunk 2 stage 1 cams
skunk 2 cam gears
hondata s200 w/p28
aem fpr
msd ignition/cap/rotor/wires

made 174/134 stock with just a few shitty bolt on's.....made 190whp 130tq at the last dyno/tune

 

peak figure means nothing for a start, you want to see gains over the entire rev range and not just peak

and i wouldn't necessarily trust dyno peak numbers anyway. i've built my car the way i want to get the performance i want, and if i get high numbers from a dyno print out at the same time....so be it

 

yea i understand and agree with what your saying'

in your opinion would the power gained throughout the powerband and/or peak be worth upgrading for, or would the gains lets say for example in a 1/4 mile run still be obsolete as to make any difference'

 

also get rid of that horrible intake, and get a true 2.5" exhaust...

 

Hell yeah. JDM ITR headers suck just as bad as DC 4-1's. I swapped mine for Profabs and went from 212whp to 220whp w/o any additional tuning. However, what sucks about Profabs is that every header I've seen has cracked at the top where the primaries meet the flange. So they make good power until they crack on you.

 

A good header is definitely a worthwhile upgrade on an N/A setup, but my personal choice would be SMSP, not Profab.

no they don't, mine has done me proud for a lot less money than rival manufacturers

What are you proud of? Your JDM header that only makes a little more power than stock that will get pounded by all the better headers that are on the market? The poster wanted to know if Profabs would make a difference in the quarter mile.
Why wouldn't it make a difference if it's dyno proven? Drag racing is all about high end.

hmmmm, ok then

i won't mention i got 12.5whp more than another car on the same dyno, i had a JDM 4-1 and he had a "better header", the rest was virtually the same setup

you can't make sweeping statements like that dude

 

maybe you had a better tune?

 

both tuned by Mase

 

whats the setups?

What "better header" are you talking about? Just because your car made more power with JDM header than the other car does not mean anything. All motors are different. If you would have put the other guys "better header" on your car, it would have made more if it really was a "better header."

this is EXACTLY the point i am making


all motors are different, and some motors respond to different headers better than others


its entirely possible that if we swapped around i would make more power, but what i'm trying to highlight is, its not a question of the more expensive headers make more power


a friend of mine had a J's Racing header, the bracket that secures it under the car busted off


he didn't have much money and got a JDM 4-1, he even admitted he wasted his money on the J's because he felt NO difference

this guy if he swaps headers may make no power gain at all, he may make loads. it depends on the motor and the setup


like i say dude, can't make such sweeping statements!

 

If you are swapping from a OEM JDM 4-1 to a good header, there will be gains, regardless of the setup. Yes, all motors are different, but no motor "prefers" an inferior header.

No one is trying to badmouth the OEM JDM 4-1. It's a decent header for the money, but there are certainly better performers in a number of different price ranges.

that is the exact reason why i purchased mine. it was cheap and was a decent upgrade compared to the usdm itr header...i just have $1000 to spend on a smsp header...

TRUE!!! The Profabs will make more power than the JDM regardless of the setup.

Tartje....What is your setup and how much power are you making with your wonderful JDM 4-1?

whats wrong with the j's intakes? mine has worked just fine for me thus far....i know a cold air set-up may yield a couple more whp but my car is slammed and i prefer for a short ram style'

my exhaust is a 2.5"....its 2.5" piping to a test pipe, to a 2.5" cutout "for ***** and giggles", and then through a 14" kteller resonator, to a tanabe racing medallion muffler........all 2.5"

i know smsp would be a great choice, but i dont have a grand to drop for a header, and my question wasnt about the smsp it was about the profab, its local, its @ a good price and its in great condition, also has a custom flex pipe already made so i dont have to dent the oil pan', i simply wanted to know if the gains from swapping headers would actually yield much of a difference to justify the price

 

The J's doesn't seem to dyno well.

If you can get the profab for cheap go for it! I was going to get smsp to replace my jdm 4-1 but opening a roth ira and paying taxes has changed that plan.
