I saw one on Steph's S13 at Irwindale it looked nice, as far as design. Will it hold up, only time will tell, to the best of my knowledge they have not released them yet

Their website says " in stock" but no pic, just a photo of a wrx manifold. http://www.prostreetonline.com/buy/dc_sports_turbo_exhaust_manifold/ntm4203b

well not too much info on this manifold there, just wondering what flange is on this DC manifold? top or bottom mount?

Yea, just like people had the EMS in stock 8 months before it was released.

Look at DC's site (http://www.dcsports.com/product_turbo_app.asp), it ain't shipping yet.

I'm waching it fairly close.My post from 2 months ago. (http://forums.freshalloy.com/ubbthreads/showflat.php?Cat=&Board=UBB27&Number=67850071&Foru m=All_Forums&Words=24546&Match=Username&Searchpage =2&Limit=25&Old=allposts&Main=67840298&Search=true #Post67850071)

it'll be another crack tacular piece!!

16ga. (0.065" - 1.65mm) 304SS...wont be long for this world...LOL.

they tried to make honda turbo headers back in the day. they all cracked. i guess they didnt learn their lesson??

At what PSI are these people running that they crack every manifold?

Im looking for a descent top mount t25 flange mani.

It's not pressure, it's heat cycles and the fact people use the manifold to support the weight of the turbo. Thin wall turbo manifolds can be made in a fashion so they do not crack. Bracing the manifold is not the answer unless you have the proper expansion joints (slip fit). The header has to be able to expand and contract with heat cycles. The header is there to direct exhaust gas only not to support the weight of the wastegate or turbo.

Will the DC manifold crack, most likely. Just like every other manifold that looks like this.

They are engineered for profitability, not for durability.

"they tried to make honda turbo headers back in the day. they all cracked. i guess they didnt learn their lesson??"
New owner ship (AEM) will have to learn the same leson.

I think its hilarious, once again... to see a company like DC sports making parts for a Nissan. (RWD at that)

These cars got no repsect when they were still being produced... now they're cool. http://forums.freshalloy.com/images/graemlins/grin.gif

Thats because the KA sucks (IMHO) and there was very little support for it to make any sort of power. The challenge of FWD was desirable and familiar to the crowd. Now that the SR is popularized and the drift "culture" fad is here, the S chassis became desirable. Can it hurt to have more parts to choose from?

I agree wit you John
No profit, no parts it's that simple.

sorry for the crappy pics they had the manifold hidden all the way on the bottom in the corner at sema..

impression.
great welds, great construction nice thick flanges even has a collector at the very bottom. i'm def. picking this mani up when it is released.

But do they offer any sort of warranty? I doubt it...And whats with S13 only? Why would it not fit a S14?

less than 2mm thick? I don't give a damn how good the welds are... that thing will come apart in the middle of the runners.

I'd like to point out that average good manifolds are 3mm. Full-Race uses 6mm weld-els.

You should reconsider, don't buy a manifold just because it looks pretty. Look at what its made of, that manifold simply won't last.

oh well, its only MY opinion, hence the IMHO! Apparently, I was not alone from 91-01, after that look how quickly the S chassis got popular

I fail to see how that entire comment was part of this discussion? Maybe some of us should go onto unrelated threads and start throwing our opinions in there too. http://forums.freshalloy.com/images/graemlins/rolleyes1.gif

My friend Ron's S13 (former JSPEC S13) is using that manifold for durability testing. It isn't driven daily but has already seen Super Street's Time Attack, RS*R Drift Festival, and about 5 other smaller events. And numerous dyno testing sessions. Hasn't cracked yet.

I plan on using that car to compete next year in Formula D.

I think the collector sucks on that manifold... all four runners should come together much closer instead of how they angle in... I think this piece will sell just because of it's brand name and nothing more... bad design and bad materials...

im not sure, but im starting to think the reason the manifolds are breaking isnt really the magnitude of the forces put on it, but the duration

i dont see how drifting and road racing can be that much harsher than daily driving with all sorts of different forces being put on the manifold.

maybe someone can explain to me?

The main difference would be the amount of heat and the duration that those high temps are held. Most likely make the metal more brittle and accelerate failure.

Brad
12-08-2004, 11:33 PM
yeah thats what i was thinking....but judging my exhaust temps, highway driving is going to be as bad if not worse temp wise than quick runs at a dragstrip or drift corner

not to mention comparing the crappy roads to a smooth sleek road course

But cornering will probably be worse for the manifold, especially when the exhaust isn't properly located and held. An exhaust swinging side to side puts the collector of the manifold in torsion, which is probably what its weakest compared to a quick spike in tension(a bump on the street).

An exhaust swinging side to side would really only put the collector in torsion(at least how the SS Auto manis and other ones like that are made), and that's where I've seen every one fail when it has been a critical failure. Otherwise they just kinda leak from the runner to flange welds due to crap penetration from what I've seen.

The tracks that the car will run on (parking lot, Buttonwillow, Streets of Willow, etc) are not exactly smooth surfaces... but at least it is being R&D'd.

This car was also one of the test mules for the EMS system for S13 SR. I should post up the dyno charts.............. incredible gains from basic tuning.
