hey, smsp is asking (@ h-t.com) how many h23a1 peeps are interested in custom headers from them. you know how we h23a1 guys lack a really good quality header for the si. this is our chance to get a quality header from smsp. what do you guys think?

if you guys are members at h-t.com let the smsp dude know that you are interested.
as far as R&D, i think the engineers can't use the same design as the h22 header, right? i would think that the h22 header was design for high rpms gains. or is there no difference?

Someone that's a member over there should tell him to come on PO so all of us can discuss this with him. I think there'd be a high demand, as long as it wasn't too butt-raping expensive.

I'd love a high quality header such as the SMSP, but realistically, I don't think any H23 owner would fork out a grand for just a header, for a few hundred more you can buy a JDM H22...

The H22 and H23 ar almost identical, just the location of the bolts. Why not have one of those custom Harley builders make one with inner and outer tubing?
The only differences are probably just in the flange. At least that's what I'd assume. Different bolt pattern and different size. Someone correct me if I'm wrong
mooney, who did it? Where is the guy and what's his screename? I wanna hear from him.

Originally posted by irishpilot I think it would be great but I wouldn't be willling to put anymore than $500 up for a header.
I think that it is crazy to put $1000+ for a header, when the materials are less than $200 or more

I would agree. You can't expect someone to spend hundreds, even possibly thousands of hours of their time to research, design, test, and produce a top-notch product and sell it for the cost of parts.
I mean, do you want to pay $400 for a POS header that really doesn't seem to do much that could possibly rob power, or $1000 for a carefully designed and produced header that can and will produce excellent amounts of power? I mean, maybe something like the SMSP or Hytech is for more hardcore people who are about trying to squeeze every last bit of juice from our cars as possible.
Well you don't have an h23, so you don't understand how we feel about a header that expensive. If we would spend just 300 more, we could get an entirely new j-spec engine. THAT my friend is a worthy mod that produces an "excellent amount of power" increase.

leptolude that is designing the custom header for the H22 was asked if he could weld a H23 flange on the header and call it good and supply us H23 owners. He said that the exhaust pulse on the H23 and H22 are very different and the length of the pipes and bends and such would need to be different to get the best performance
I think the reason that alot of us H23 owners wont put alot of $$$ on the engine at this point is because we dont know the potential of the H23 in the NA aspect now that crower has some cams out. I mean if I knew that the smsp was going to drastically outperform the dc unit then I would pay the extra $$$.
have any of the H23 owners modified the dc for better performance?
i think the main reason no one wants to spend a $1k is that almost all of our cars have over 100k miles. obviously most people would spend more (even though $3k isnt cheap) on an h22 and have the same power stock as a semi built h23, granted you will have different #s i dont think its worth it on a platform where there isnt much else. no IM made in the aftermaket so far, ONE company that hasnt even officially released billet cams, its just not a b16 lets face it
^^Who have YOU talked to, to get the idea that an h22 is 3 grand for a swap?? Motor and tranny can be bought from Osakamotors for less than 2 grand. Unless you're contributing install work as well, but that's what a helms manual is for.

$2000+ for 30 hp and 1 tq. i would not say that is an,"excellent amount of power" increase.
the header would be a great mod for us si owners that spray and do not want to go the turbo route.
^However, once you've got the H22 in there, the aftermarket opens up for you. Not to mention that once you've got the bolt ons, it becomes costly for any mor power inprovement. With the H22, you're already up 30, and then you can add the bolt ons there.
