ok so the last thing i need to get the wrap up my build are some bigger cams and a good header. ive heard a lot on the rmf and smsp header but they are way high. i can sacrafice a 2-3 whp vs saving 400.00. i just want to know whats going to give me the most bang for my buck. for those that dont know heres my setup. ive been reading up on them all but they all claim to make massive hp but i know the dyno charts can be tweaked. i know on the esp site it claimed 20whp. also if any of you guys have one for sale then let me know to. new or used.

h23vtec
weisco .40 11.5:1 with stoke and thick head gasket 12.2:1 if i calculated right
crower valves, retainers, springs
hoping to get some sk2 pro series stage 3s if i can find some
port and polish
intake pipe
stock injectors, tb, IM maybe a euro IM if i can find one

please only post if you have the header. no hearsay please. setups would be nice as well with gains and dynos

Chris, if you'll settle for pro2s, rosko has a set for sale. I think they'd do nicely for you.

The SMSP and the SSR (not on your list) are both awesome headers. So is the hytech, but they're all over $1k.

If you can deal with worrying about it cracking, the camp seems to be a good deal for the $$.

 

I have the Hytech on my H22 and I love the quality, fit and finish of the header. I cant tell you how much if any HP it made because it got put on as part of a larger project.

 

yea im not trying to drop a grand for a header if i can get a camp1320 and see similar gains but if its going to be a drastic difference then ill bite the bullet and go with the rmf or hytech or something

 

Just FYI, RMF is done making honda headers as far as I'm concerned, if you buy one from him, you'll probably never get the header or the money back.

 

damn its like that

 

greddy w/ modded collector is working quite well on my setup.
a guy with a similar setup with an smsp header is making less power then me. But that doesn't mean its the Greddy header making all the power. But I think its well worth it for half the price of a custom header. Although I am upgrading to an RMF or SMSP.

buying a REAL custom header will save you in the long run. Ask rosko and many other members about their problems with the camp header. And i wouldnt put any money into an ESP header because it looks like a backyard DC sports.

SSR, SMSP, and hytech are very top notch choices. You will NOT be let down by the quality or the performance. Cant say the same for the others.

 

Hytech is the shyt. It's an awesome header I know this first hand

just my .02 cents

 

buy a prospeed if you want it to rust out. their headers are paper thin.

 

good stuff guys keep it coming. the way it looks is that ima drop a grip on a good header to save myself the headache down the road

 

If you look at page 69 of Honda Tuning, (current issue with the red nsx on the cover) the civic project build by Endyn/darton sleeved.

They are using a Hytech header. This is on a civic that makes around 150 hp per liter NA and built by one of the best engine builders in the import scene, they chose Hytech for a reason.

Hytech also keeps most headers on stock which means less wait, unlike other custom header Co.'s.

up

 

smsp headers ftw

 

i've heard great reviews about the smsp headers.

 

but i also had a buddy that used the rmf headers and they gave him good numbers judging from the dyno chart.

either smsp or rmf will give you good gains.

 

Well although I am OUTGROWING it for $500 you can't lose with a Vibrant. It isn't going to make power like a HyTech/SMSP/SSR-DTR but its 1/2 the price.
I'd say the HARD decision is ahead of you of you want a $1k+ Race header.....You have 3 Awesome Co's to choose from.
For under $500, there is no choice.....Vibrant FTW!
As far as power: On my ~200whp setup I saw gains ACROSS THE BOARD of 9whp/6tq over the $100 cheaper Greddy header.
Vibrant Vibrant Vibrant Vibrant Vibrant Vibrant Vibrant Vibrant Vibrant Vibrant
If you are a little patient you can get the new 2.5" when/if it comes out.
Theres nothing wrong with the older one, but you may want to do a 2.5" collector on it.

I know in this world you have to WAIT for custom headers, but why do you need one when HyTech Spec1/2 are in stock!
I don't think many people here NEED a custom designed RACE piece....Just my .02! Not to mention John is a great guy!

SSR

 

I was very impressed by how fast a local guy got his Hytech.

It's a lot like my SMSP. I wonder if it hangs as low

 

i had the HYTECH manifold on my old setup and i have dyno graphs of before and after showing 18WHP peak gain. other areas in the middle of the graph actually gained closer to 30WHP. back then i paid 1100 for the header.

the setup was as folows: jdm h22, euro-r maniflod, hytech manifold, hondata s200. this setup made 214whp/165wtq on a dynojet, i have the graph in front of me.

i then added type s cams and made 219whp/164wtq peak on the same dynojet.

then added crower 3,s and made 230whp/162wtq peak on the same dynojet again. but w/ a very noticable loss of midrange power, as much as 25whp/15wtq in some areas.

 

damn thats straight as hell. looks like im going to wait and go with a hytech or smsp.

Cam gears could have tuned out some of that midrange loss, when I ran crower3s I ended up with a big loss in midrange before I adjusted the cam gears, I got the midrange back by sacrificing about 5whp peak.

Good info though

 

i installed crower camgears w/ the stg. 3's but there wasnt a significant difference either way w/ them being adjusted. i wasnt concerned w/ peak but rather midrange for daily driving at that point and after several pulls of cam timing adjustments i finally gave up.

i figured the head needed to flow better to allow the crowers to work properly so i gave the head to jim justice but i had no luck after getting it back on the dyno, ended up losing more power throughout except for a small gain at the very top. maybee gained 4 or 5 whp but it came at a big loss in the midrange. a big cam w/ large volume but less velocity in the ports = loss of midrange and a peak gain. i should have known better than to port the head on a street application as i have had the same luck w/ b series midrange loss from portwork in the past.

 

awsome thread!
