I know this topic has been beaten like a dead horse. Bare with me. I've ordered a header from Hytech which they say is good for a 2.0L high compression engine. I'm simply thinking if I'm going to spend a wad of cash on a header, is there anything out there in your opinion that I should consider and why?

I've been looking at:
Mugen (both headers)
Toda
SMSP
DTR
Hytech

I suppose to better assist in this post, my requirements are going to be gains in the mid and top end. Though I think that's a given.

I've tried to find flow charts, comparrison charts, testimony of 'before and after' and have come up with nothing. It's an expensive part and simply want to make a well educated descision.

Thanks to all that view

Aloha,

(Chris F want to do some spell checking? )

 

The only headers worth looking at the ones that aren't from the JDM manufacturers in your list.

(in no particular order)
SMSP
DTR
Hytech

I would add RMF to this as well.

The primary reason I state this is not because I think Mugen/Toda are junk, but rather they never designed their headers to run with a 2.0L applications. Only the USDM tuners have taken Honda power production so seriously to warrant (in this particular discussion) custom headers to be built.

Again, not saying the Mugen/Toda headers won't work....it probably won't allow your motor to reach its intended potential.

 

Definately I would go with custom header for 2L. I know that both Hytech or SMSP have designed headers which have been optimized for a 2L. Personally, I would go Hytech but I'm biased.

 

Don't forget Burns Stainless; Casey posted one of their one-off jobs in the All Motor forum.

 

I've got a custom built AN-R with a 3" collector. I've never dyno'd it against anything else although I almost bought the Hytech. Honestly though, with any of the good ones (Hytech, SMSP, DTR, RMF, AN-R) you'll make good power. Stay away from the JDM crap...

 

SMSP

Header builder who road races.

RMF all the way one of the best headers made today 2.5" for street/track or 3" for all track

 

If you've already ordered a hytech, then the point is moot. Just make sure he knows it's for a 2.0L and your intended stroke, bore, cams, and compresssion + head flow numbers.


And the expression is "bear with me," not "bare with me" - I don't want to 'bare' with you, period.

 

This is true, tell John about your setup and he will build it to match, I guarantee you won't be dissapointed. I have a custom Hytech on my 2.1L engine and it seems to be working good. Just be prepared for a bit of waiting

 

found this he is from seattle

Doesn't Hytech use some "unique" technology such as anti reversion chambers and super secret patented designes?

I think you went the right route, Brandon. A little $$$$ for my liking, but the quality will definately be there.

I might get my car running before you do

 

hytech can't even TOUCH the power an RMF or SMSP can produce

personally...RMF would be my choice
next would be SMSP

after that..they all pretty much suck

Where's your proof of this?

 

5,000 dyno charts all over the internet. customers chaning out cause they want more power. hanging out at 2 different dyno's and seeing it first hand

So do you have any dyno comparisons?

I'm not doubting you, but if you're going to make such a bold claim you have to back it up with evidence.

From what I understand, John builds most of his headers for stock motors and any additional change in volumetric efficiency will adversely effect the power potential of his headers. If you had John custom build you an application specific header that took into account every detail of your build, then you'd make excellent power with it until you did something that again changed the VE. There's no doubt that Dave and Randy build outstanding headers, but just because John does it differently (and often making "picky" headers in the process) doesn't mean that his products are inferior.

 

Dyno charts plz

 

i have made 230+ whp on my 2.0 w/ a JUN header... and while it may not be the best out there.. you cant argue w/ the numbers.. makes me wonder if i could pull 240 out of it with a custom header and testpipe

 

Brandon did you order a HyTech? Is it going to arrive here soon?

HyTech does offer a 2.0L header, and it will be better compared to another off-the-shelf header.

However, the DTR, RMF and SMS both will produce more power than the HyTech 2.0L, at least from the charts I've seen. But when it really comes down to it, the difference isn't huge, and if you've already ordered the HyTech I would just stick with what you paid for.

If the header is coming here, I can always do a dyno comparison with my motor

 

Unless tested on the same engine, on the same dyno and preferrably also the same day I would think it's hard to back up these claims, can we all agree that all the headers mentioned will give good power?

 

my motor is not 2.0L but this header will work i guess
