what the hell...i want the SMSP header but i cant find it n e where??? what the hell...jeff at import builders said that i gotta order it directly..what the hell is the deal with that...does anybody out there no where i can get a hold of this header??? and how much is it???????

someoe please!!!!!

 

IM SMSP

 

For some reason, I think thats really funny.

 

hell yeah..its really wack that i gotta special order...but it also means that dave's headers are exclusive..so...isnt he on this board??? what the hell....so does anybody have this header...and how much is it??????????

 

Whoa settle down, your gonna have a STROKE. take it easy and send dave a instant message, but please cool down, before your heart explodes

 

lol lol...sorry...how much is it??? nobody answered that yet

 

they go for around $950

 

Where are the SMSP headers? Well one's under my hood.<LOL>

Amazing to drive. I've never had a header make as much difference as this one.

Contact Dave for the price as there are several variations available.

Damnit, $950 for a header?!?!? How much better is that than the JDM 4-1?

 

like 3 HP!
as nice as the SMSP header is, I cannot justify spending that kind of money
on a header.
JDM DC 187 peak HP $280+/- 137 TQ
SMSP 190 peak HP $950 136 TQ

$950 - $280 = $670

$670 / 3HP = $223.3 per HP over the DC header.

I think I'll go with the JDM DC.

 

Your talking about peak hp. Very useless.

 

a STROKE... damn, lol. having a hard time breathing..

D

 

LOL, I'm sure Dave is going to go out of his way to set everything aside and build you a header now

 

damn $950..do u really think that the smsp header will make a big diff. over the jdm dc 4-1???? most likely the smsp header or any type of high quality header is gonna b better for a highly moded car vs a car with hardly any mods...the header just flows better am i correct??? now sayi have a dc jdm with a lot of mods high lift cam ect... do u guys think that the jdm dc is gonna b a bid difference..i mean im not gonna use if for any track racing..i mean i live in NJ gimmie a break..just some road racing and once in a blue hit the stip...cause that extra money that i can save can def go to something else.....guys help me out here!!!

 

Probably No, the conclusion of the great header test between the headers tested was that there was little difference in HP. It wouldn't make a big diff. We're only talking a few HP here and there. However the SMSP was not in that test. If this header is absolutely spectacular. It might be worth the dough.

[QUOTE]now sayi have a dc jdm with a lot of mods high lift cam ect... do u guys think that the jdm dc is gonna b a bid differenceQUOTE]

If you have a lot of other mods then your next mods will generally yield higher gains than if they were put on a mildly or unmodified car. For example putting a new intake on a turboed car, usually gives more HP than putting on a mildly modified bla bla....

If you are staying NA, intend to spend a hella lot more cash on the car, and want as much HP as you can possibly net, get the SMSP. Many reccomend it on the forum. If you don't intend to spend much on the car, then you might be better spending that money towards cams or something else.

If you want to go turbo don't buy any header. If you go Supercharger get a Kamikaze. This all my opinion based on what others are running.

 

There was little to no difference because the cars were NOT Tuned after the headers were installed, Also The SMS was tested. For most of the useful area for street and road race use the Spoon came out on top for a stock ITR, The SMS Did well in the high range of 7K up along with the Toda

 

Is it very hard to get Dave to build a header? I mean, If I decide to try to get one, is it going to be a few months before I get to pick it up?

 

let's also keep in mind that the "great header test" was made on a pretty mild setup. If Dave's header was tested on a "built" motor, i'm sure the #'s would have been much different. Also, tuning is essential here. Power under the curve, not peak, should be stressed here.

 

I emailed him a few weeks ago about the header test header and catback...but that money ended up being speedtrial money. That got expensive. I'm planning to hit him up again with tax money.sorry. I just saw an opertunity to ask a question that I had been thinking about for a while and not be that d@ckhead that started another header thread.I'm considering spec a's, but I'm trying to make sure I've thought everything out before I open that can of worms. I can afford cams and a header, but what about 2.5 in cat, gears, engine managment, dyno time, what did i forget?

The header used in the test was the same as Racebrewer's. It was the first time the ITR header was dyno tested on a stock ITR to my knowledge. While the header can be used on a stock engine with good results, as Racebrewer stated, it's really designed for an engine with more mods. The primaries start out at the same size of the DC JDM (1.75") which are just about the same as the Toda, Spoon, Jun, Type One, Mugen at 45mm (1.77") but they step up from there. ALL the JDM 4-2-1 headers use 50mm (1.97") secondaries, mine are larger. The collector is still 2-1/2". To get the most out of the header it needs to be tuned, both the engine and the tube lengths. There are set ups out there where the secondary lengths vary by as much as 2x and both of those perform very well for their respective mods and engine types.

So while the header didn't come out on top in the low to mid range categories in the header test on the stock engine it was very close and it did it with the much larger tubes. As another example the header that MikeK tested was built for a 2020cc engine and the primary tubes are larger than the ITR's and the secondaries are much larger. But Mike ended up going with the B17 crank at the last minute and only has 1847cc but he didn't loose any torque way down low, so that's a to the parts used, head work and his tuning.

I can't tell you what header to purchase, you have to decide that for yourself based on your finances, future mods, application you want to use the vehicle and how serious you are. I think the DC JDM and ITR JDM headers are good pieces but as you mod an engine and raise the redline they have their limitations due to the tube sizes. That doesn't mean you can't run them on a modded engine or even a B20 you just won't be getting everything out of the engine that you can. Just look at the torque curve of most B20VTECs that run these headers.

As for ordering, if you're interested you can contact me at smsproducts@novacoxmail.com. I don't have any distributors because I can't stock them and the wait should be 2-3 months right now. The price that was quoted in this thread was correct for an ITR header, if you feel it is too much the only way I can answer that is you could try building one your self and then estimate what you think your time was worth. Don't take that last sentence as an attack on you, I just don't think the majority of people realize what's involved in building a custom header or exhaust and that doesn't even include the time doing the drawings.

You can find some more data on headers at https://honda-tech.com/zerothread?id=118381.

FYI, Depending on my schedule I may be part of a Spoon / SMSP comparo soon on a modded B18C, so hopefully I can give you some more data to review.

 

Sorry for starting this controversy, SMSP, i know you make great headers. I also understand why your cost so much more than say, the JDM ITR or DC is because you custom make your headers. These other headers are cookie cutter pieces that are cranked out a million at a time. Thats all i was trying to say in my post, i just didnt explain myself very well.

 

No prob.

 

Could you give a brief description of the modifications on the header test mule? The baselines seemed much higher for a mostly-stock R. TIA...

 

Canukr would be the better one to ask since it was his car. It had a CAI intake, not sure if Comp Tech or AEM and a fresh tune up done that day and an oil change with Mobil1 10w30. It was a 97 ITR. The tests were done on a Mustang Dyno. This was the first time I had any experience with one of them. I had read that they read lower than Dynojets. We ran the stock set up with a 2-1/4" Car Sound cat and then went with a test pipe and my 2-1/2" system with the stock manifold. Then we just changed all the headers out. We ran a 2-1/2" test pipe for all the headers except the Comp Tech which we used a 2-1/4" x 2-1/2" stepped test pipe.

Yes, all the numbers seemed high for a stock ITR considering I've seenn some of those running Toda Bs. But I wouldn't get to caught up on the fact that the numbers were high since we were comparing headers and I wouldn't try to compare them to something recorded from another dyno.

 

Great, thanks for the info.
