S2000 Header Building + Testing - Part 3
HTML-код
- Опубликовано: 2 янв 2024
- We wanted to test a few headers to see if and where the power changes.
We tried 5 off the shelf headers and then modified some then build 2 of our own from scratch.
There's a lot of power to be found in different RPM ranges, playing with diameter, Merge points, step points and over all length makes drastic differences.
We will make a separate video on header testing and go over the ones we tested. The headers will be for sale at a discount for those that are interested.
In Part 4 we'll get some real world driving impressions and test our car against some other S2000s and get some driver impressions for 2 of my friends that own S2000 and drive daily.

The time and money LHT Performance has spent so we can buy the correct setup the first time is priceless. Thanks for all your R&D and great content as always. Happy New Year!
Thanks so much 👍🏻. Happy New year to you.
Agreed.
Amazing work. Hopefully, you guys will get more support. People just don't understand the hours that are put into quality functioning parts.
Similar RPM on the highway as my Miata with Torsen LSD. Also I’ve had a 4” rigid tube below my Integra stock airbox for over 20 years, that leads behind the turn signal, with a velocity stack on the end. Similar concept to the Comptech icebox. It’s the “BSQ DIY Icebox” mod from back in the early days of Honda-Tech.
This is prime content. I love seeing how each thing impacts power and torque.
Even after watching the videos it's probably hard to appreciate how much time went into it.
That s2000 probably holds the record for most header swaps
Thanks. I’m seriously going to change the header studs as I know they have been over used. lol. Many hours have gone in behind the scenes and I really would like to tweak further. Without changing cams etc, I’d really like to see a ligit 250.
John: Very interesting that your final header and tuning came out very close to the build you did on my white '08 AP2. Quick refreash. 205 HP bone stock on the dyno you used back then. Final peak was 242 rwhp with torque in the 150's peak. Stock 4:10 rear gears, your custom "step" header then which I believe was 1.875" to 2" with 2.5" collector and the 2.5" bypass" exhaust with magnaflow mufflers in that stainless system you built for me then. VTEC changeover with the Hondata reflash was 4,500 rpm and we used the bone stock airbox and and a K&N oiled filter. Dead reliable, very torquey. So much so you could short shift at 7k or buzz it to 8,500 which was rarely needed. NO ONE believed back then how..few changes (5) you made for those results. I was an idiot to sell THAT car. But rides I give and 360 burnouts made believers out of all who rode in or raced me. THANK YOU again. Amazing car and the F22 is marvel of Honda engineering and your LHT..touch👍.
You also had a very strong car, I believe my car is a little lazy. The gains do show pretty good on my car, but with what we’ve learned I think I could have got 250 on your car. My friend Christian also has a really strong car that may show some great gains too.
I have some more ideas in the future I may try too before going back turbo.
One day you’ll get another one Victor.
Amazing work John! Been following for years! And its great to see an LHT NA setup being RND from start to finish.
Would be good to see the differences on the new cold air box mod vs adding the front snorkel to the airbox and seeing the IAT temps.
Amazing work! The only thing that holds this motor back is lack of variable cam timing. Your header makes it almost irrelevant.
Awesome video! Thank you for all the time an effort. The community appreciates you.
I love your content, attention to detail and how you explain what you experience. Amazing!
You're doing great work, John.👍🏼 I'm sure this answers a lot of questions S2000 owners have had for years. Having access to all those different headers and the ability to go through all the various setups is so time-consuming and cost prohibitive, the average guy couldn't possibly do it, so I think it's awesome that you're putting in so much time and effort to take one for the team.👏 I like your scientific approach of documenting the results and real-world testing for all to see. Speaking of scientific... that bit around 13:36 is the best! I remember that guy from back in the day.😅 Love it. Cheers, buddy!
🙏. Thanks so much for
Finally someone is putting time into creating the ultimate NA Honda S2K. If there were some decent cams to bring it to 250, that'll be so sweet...
This has been done already lol
Just wanna say LHT performance is the absolute best when it comes to Honda knowledge! Who else agrees!?
🙏. We just enthusiast that’s been in the game along time, we’re still learning too.
Awesome and very informative as always❤
Man I will definitely buy your header. Thank you so much for all the time, love, r&d ,hard work you put on this platform. Love this channel.
Thanks so much John for all the work
🙏
One of my favorite videos you’ve made man! I love to find the small details in every part to make better, when done with several components the driving experience is greatly improved. Great work as always!!! One gripe I love the loud exhausts 😂 it’s a weekend car not a daily, let it rip. Videos of my s2000 and it’s insane sound are on my channel.
Thanks buddy. I do enjoy tweaking and tuning, it would be easier if my views were higher.
Loud cars are fun on the track, I’m too old for a loud street car. Plus I don’t like to get tickets anymore. lol.
@@LHTPerformance tickets are not fun at all… loved in California for a brief time and got pulled over and ticketed for everything… intake, exhaust, tint, being lowered etc. was so annoying however living in northern Arizona and now in Nebraska they don’t ever pull you over for modifications and also no smog so it’s very nice enjoying the freedom of having a custom car. I would definitely love to see more dyno experiments and tweaking to find what works best. Not sure if you’ve ever seen the youtube videos engine masters, while v8 platforms for mostly classic cars there is a ton of cool videos there, would live to see some s2000/Honda videos like that. Thanks for all you and the LHT team do. One of these days I need to make it down to florida and go to one of your events or maybe catch a drive with you guys on the dragon as that road is definitely on my bucket list.
Appreciate all the info on the testing, I love stuff like that!
If I had more time I’d leave it on the dyno and just play with ideas. Sometimes the best gains come from experimenting
Awesome work guys 😎
Great video series. Thank you for sharing. 👍👍
I have the URGE produced Gernby scavenger exhaust. Its claim to fame sounds similar to the header you have developed, massive scavenging effect in the midrange without sacrificing top end. One thing their testing showed is a minimal gain with any header, I am curious if you think your scavenging header and the gernby exhaust combo could make even more midrange power.
I was thinking about this precise combo.
Buddy... This is incredible content. 👏
This is great data, thank you for sharing! I've gone through several N/A setups and headers on my AP1 and am currently at 238 whp / 158 wtq STD Corrected DynoJet power with a factory 2.0 bottom end. The next iteration for this engine may need one of these headers.
So humble. ... You guys got some good info he can learn from also. I still go back to your all motor videos for info 🙏
Thanks my friend. That’s some good power on yours. I feel like my car has always been a little lazy. I have 100s of files of S2000s and many AP2s will be 218-220whp totally stock. I do have more R and D plans with some more header designs and then possibly play with the manifold and increase the plenum volume.
@@LHTPerformance I'll be interested to see your results. I still have the OE intake manifold, it's just port matched to a 70mm TB. I feel like there is some power to be unlocked there.
17:35 Great job on the header, John! 🍻
Best in business period!!!
LHT u did it good job👏
thz u for modify the header… show all to us. ❤
Those are some great numbers. Seems like that air box mod makes a decent difference. Would love to see what numbers an ap1 makes with these mods.
We’ll try and do it.
Yes I'd love a set of those headers for an F20C if they work as well as they do on the 2.2!
Lots of hard work involved here, but also the skill to arrive at a good outcome :)
On my 4th S2000. Did the autox/street thing. Did the time attack thing. Did the w2w thing. Now I'm looking to do the OEM+ thing for nice cruising and the occasional track day. Really looking forward to pricing on this header and/or exhaust.
Hey john and crew happy new year here in holland came the s2000 with 241pk. F20c. ✌🏻🇳🇱
Some are built different 🤟👽🛠🎬
I hope I can buy a full NA kit from you guys at some point when available
Is Esther modeling your merch line?? Awesome video as always guys, keep up the amazing content!
If you guys offer that exhaust setup will definitely purchase
Would love to see comparison in power to OEM airbox. Once the header is finished put it on another car, with stock airbox, to see how it performs! Well done! :)
He attacked it with great passion, dope.
I’d take that tq on a street car anytime, especially with a Honda 2000 that has none to be begin with. Nice work 👌🏼
I kinda wanna try something like that fresh air mod on my nd miata. None of the "cold air intakes" make power from all the tests i have reads but I consistently see IAT's at 30f over ambient while moving.
Cool vid
Awesome video! Very informative and great for the s2000 community. Any plans to modify the intake manifold or go with a larger throttle body? I feel like it would be helpful for the s2000 community to understand if any further benefits can be made in that area as well for this NA plus package. Thanks again for the video! Keep it up please!
Thanks.
That might be something we’ll try in the future.
Love the info. Im building an na ap1 myself. And we all know how hard that is.😅i was gonna do it with the stock header but you got me wanting a header now😅
Thanks buddy. There’s more power yet I think. I do have more plans and header tweaks I’d like to do.
I neeeeed this header
Awesome video. Please add an option to use factory cat and stock heat shield on the header.
To have the header in tune it needs to be longer than the stock location. That’s was part of the tuning testing. You’ll notice where the cat is positioned
Man, those gains in the middle will make a different! ill wait for you to release your header before I get the car tune.
Have you tested the Ballade sports race header? They claim some good gains. Also what’s your thoughts on a fluid damper?
Very nice results! I am curious did you do any testing with an ap1, and if so did it produce similar gains?
I didn’t, I don’t have the AP1 still. I will be doing more testing in the future
Do you have a before and after for the coating on your header. Always curious if there are some gains due to extra scavenging by trapping in the heat.
First. Good work, glad you guys are going through and showing the trial and error too. Its tough with the ap1 though, needing to run a stand alone to see the benefits of this..
I’m going to a before and after with zero tuning also
@@LHTPerformance that would be great. Not to sound like a hobo here but i remember guys on s2ki NA forum using the adjustable FPR along with an apexi neo to adjust vtec lower...a caveman solution but supposedly was all that was really required for NA
@furiangameclips I did plenty of those too. Changing the Vtec cross over and leaning out the AP1 up top always made power. I still have a couple of VAFCs 😉
can you please check if you take out the water from intake make a difrence to iat?
What's the wheel & tire sizing on this? LOVE the athletic stance of this build.
I wish I can bring my 2000 S 2000 it's black with a Silverstone genuine hard top that needs to be color matched and I wanna do many things to it and you guys seem to do the right job but I live all the way in California pretty far LOL
I wish i could know the numbers with SAE smoothing!
I need that cat back exhaust ❤
1600rpm is where the remark exhaust does it's drone. The stock exhaust does it too, but it's very muffled.
Yes, it does a little. With the UK mod it has a tiny bit up top too. This one after 2100 rpm’s it almost silent. Almost too quiet. lol.
This car held the horsepower per cubic inch record for quite some time... I'm sure the modifications you have done, actually make it have more horsepower than the Ferrari motor that took it off the podium......
Do you have any in house 9th gen civic si sedan engine parts?
No LHT titanium intake elbow for this NA build?
How much power could i make by just changing the header and exhaust on an ap1? no tuning.
I’m ready for the LHT turbo kit please.
ruclips.net/p/PLIIt5903IeLPQskBMO67u_Qt3F8IJ8e5M&si=tOtyUmdf-0nkhbaJ
Wish y’all could build a super nice titanium exhaust for my civic
If you bring it to us. We can build it for anything.
What’s the best header for the s2000 NA?
Is the header available?
Bugs in the scoop would be the least of my worries living on the west coast.. 🌧️
Yep. That’s the draw back here too. I will do some testing in heavy rain. And we get some crazy rain, just not standing water.
Could be some money in it for your if you start making 86 Toyota headers since they finally got a decent motor
Happy New Year!! Great video. Want to get my clutch done how can I reach you guys to schedule an appointment, I’ve tried emailing you guys but haven’t got a response yet.
We were off from Christmas to new year. Email through the site and Esther should get back to you.
What are you selling these headers for? The 240whp is from what changes to your car?
If you watch all three parts, you can see where the changes came from. The header making the most power. The headers I am selling range from $200-$500. $500 being the Skunk2 mega power. That one made the most power as a bolt on.
Wait so headers make power? I thought we all settled on they didn't
Hi very interesting and informative work and testing you have done. How can i contact you?
Hit me up on IG
2500 clutch presses to break in a clutch? I don't think 300-600 miles suggested break in period gets close to that
I'm a easy guy, s2k and LHT get a like thank you
Have you ever seen the ballade sports one ? I gained 10 horsepower when I switched to it on my ap1
Would love to hear thoughts on this one. I have considered their header as I have their single exit exhaust
Most of the tuning we’ve seen is from extending its length. The stock length header isn’t going to make any drastic changes.
Without literally spending 8-10K on an F20/F22 and staying N/A, you're not going to make much power as it is pretty maxed out from the factory. I have seen some N/A Spoon and Mugen S2K's on ITB's, Hondata, wild ass cams, etc. make like 300whp N/A but again 8-10K of mods/work. I do appreciate show the subtle differences in tuning the F20/F22.
I’m just experimenting here. It more about making the car a little quicker without turning it into a turd. Itbs , open header and lumpy cams to make 300 would make me hate it.
I still things 400whp with boost leaving it otherwise stock is the way to go IMO.
But I’m having fun and sharing it.
@@LHTPerformance Yes I like your approach to OEM+, and I don't see you spending that much money on mods unless you would go with what you already went with your Turbo S2K. It's always fun to watch your builds b/c you do them in a smart way. Do you ever watch Dustin Williams Channel? He's got some great builds.
@@matthewmohri9990 Yep, it’s fun and leaning at the end of the day. I haven’t watched his channel. I try not to get too OCD, but I’m pretty picky. Tiny things that I think I can improve, bother me. ( Hence why I’ve sold some cars others things are amazing ).
I’ll look at his channel. Thanks.
Different goals man.
To me, 20-30whp gain is huge and would bump me up a class in my racing series lol ppl forget how these cars are bespoken track cars and every little bit counts massively. That much horsepower alone would shed tens of seconds and more on straights.
F22 👎🏻 - F20 👍🏻
How the heck do you come up with that decision 🤣🤣🤣
If you guys offer that exhaust setup will definitely purchase
