AEM Intake, HLC, and Headers? Mostly Headers Q's

I know the CAI intake will give me some nice easy gains, but what im mainly wondering is whether or not headers are worth the money, and what the gains would be if i purchased nice ones. any input would be great. thanks a lot!

headers will give you the most gains...depends if you want to get carb certified headers or not...carb certified will run you 1k(comptech)...others will run you $300ish

most of the headers will give you the same gains...around 20 if not a tad more...but that works in conjunction with mods you have to make the most out of it

yeah, headers seem more then worth the money to me. 20whp for $300-$400 is ridiculous for a Honda.

so the headers are dino proven to give me 20 whp? i mean thats a ton to the wheels if it was to the crank that would be more believable, but i had read that they do wonders and i have also read that they dont give you that big of gains, i understand the quality difference, and mostly what i was thinking of doing in the spring was an AEM CAI, a HFC, and the headers, and i was wondering after those mods what the differences in performance would be, all my buddies are euro guys and they think the intake will do just as much as headers would for my car, so im pretty anxious to prove them wrong haha. thanks for all the input guys.

Dyno proven give or take a little with different circumstances. If you want performance ideas go to the CL forums on here. There is a whole Dyno section with Dynos posted. Throw a $25 crank pulley on, about $50 with the belts and you'll free up another 7-10whp.

For the pulley, like yeedatoy said get the cheap one shipped $25 from ebay brand Option's one or Boomz and they are the same under drive pulleys which I got it three years ago also new belts for under drive pulleys.
Another choice is UR pulleys, they make stock size and under drive but it will cost you around $180 to $200 shipped. Between two size under drive will give you more gain .
If you are not planning to put more than 600w audio sound system, under drive one is the way to go.

Here's my threads back more than two years ago...you can refer some info in there.

21whp gain CT headers a on cl-s here's the dyno https://acurazine.com/forums/2g-cl-dynograph-gallery-51/cl-s6-ct-headers-823346/

Somewhere there is a crank pulley dyno showing 13whp gain with the UR pulley.....2 whp for every pound shed from the pulley.

if im not mistaken there is a "substantial" difference between the type S cars and just standard TL's. 20 to the crank is reasonable. 20 whp on the other hand hey I just just go get one of those genuine ebay chips...


The Tunesport Performance Module is the answer to today’s high fuel prices. We are all looking to squeeze that hidden power and fuel economy out of our engines. The Tunesport Module sends a modified signal through an engine data sensor, causing your factory Engine Control Module to reprogram itself for a more efficient air/fuel ratio, essentially unlocking up to +75 Horsepower and up to +8 MPG in your vehicle!

I mean jesus look at those gains!

just saying 20 whp is trash. to the crank yes.

First off, I know the difference between crank and wheel horsepower. Secondly, I've seen a TL-P dyno 18whp with $130 headers. Thirdly, 20whp was a figure I thew out there for a stock TL, I've heard of gains up to 32whp. Go look around on J32a.com, where people have J swaps in Civics and Integras and are much deeper into modifying the J than most on here. Then you can come back on here with your BMW username and try to argue with hundreds of members who know that you have no idea what you are talking about.

30WHP automatic CL-S

https://acurazine.com/forums/2g-cl-dynograph-gallery-51/01-cls-236-199-15k-miles-back-2002-a-490706/

Notice it is SAE corrected, and that the intake added about 8whp, which most members on this site knows is the norm.

This guy doesn't drive a Type-s. If I was mistake wasnt there a 40 hp difference between the two? so this doesnt apply to this guys car.

German cars are the most hideous and overpriced unreliable pieces of crap next to Cadillacs. I would never even consider it. If I spent 40k on a car you would see me driving an NSX, not a bulky car shaped like a turtle that upper class vagina whipped men buy for their wives.

35hp difference. If you took your head of your ass and pointed it towards your computer screen, I said dynos show 18whp increase on a stock TL-P. TL-P TL-P TL-P TL-P TL-P..yes the Type S has a larger intake, manifold differences and a different exhaust system, but what you're not understanding is that I'm saying that headers are capable of producing peak gains of much higher then 18whp, as I showed in the dyno PROOF. I don't know what bothers you so much about a $100 header showing 18whp gains on a stock vehicle, maybe it because $100 will buy you nothing but a valve stem on your "look I have a little penis mobile."

between e34 and 99tl, I will bet money on yeedatoy.
between nsx vs M5 to each their own on straight M5. On track race nsx can beat M5. I am not bias though.

Your 27 years old. 27 fucking years old. Do you understand how immature you are being? Grow a pair? You think the car you drive has an influence on how much of a man you are?

Personally in the BMW world, I am a 3 series fan...the new 3 series coupe is pretty sick to be honest. I would never own one but I must say they are nice...I got stomped in my full bolt on equipped h23/vtec swapped CD5. I'm pretty sure the E34 was a late 80's early 90's car that may have been a nice car at the time but is inferior to a 2g TL, which was a very high rated vehicle for it's class. An 92 NSX is considered technologically avanced even in the present...20 years after it was first built...and can stomp many higher powered cars with a much higher price tag. Anyone who talks down on an NSX just doesn't understand it's history correctly. Furthermore, it always amuses me when someone comes on a Honda forum and talks down on Hondas. Its just asking to get gang banged in the anus. Usually this happens because they've had their ass handed to them by a 1.6 liter civic and have some sort of never ending vendetta...lol

e34 540 would murder a TL. and a better race would be an e36 M3. that would beat a nsx around a track. easy.

havent lost to civic or teggy yet. never said the TL wasnt a nice car, its a great car but to say inferior is a big step my bmw has every option a 2g tl has. and I never spoke down on an nsx, an M5 wouldnt be a fair comparison

You should make a thread in Car Talk and display the project. This thread is already way too off topic.

Not really, Nurbergring times for the NSX-R and the CSL M3 were almost identical. The NSX has 276hp and the CSL has 360hp. NSX has a smaller motor and less torque. So whats more impressive...the 20 year old car with less power that has a faster 0-60 times and only weighs 200lbs less....I think so. Try comparing a 1990 production BMW with an NSX and see what you come up with
