OBX Mitsu Flanged Tubular Exhaust Manifold

[kawboy]

About a year ago a similar thread was made regarding the Xo2 Racing "DNP" Knockoff tubular manifolds.

A couple people including me purchased them and the turn out was pretty good

OBX seems to have released its own version of a tubular manifold, both mitsu flanged and not a DNP Knockoff.

eBay Motors: OBX Turbo Manifold Header 90-99 Eclipse DSM 4G63 GSX (item 370147513898 end time Feb-18-09 19:42:52 PST)

I'm curious if anybody owns or has used one of these?

NOTE: These are not the T3, T3 Ram Horns, nor DNP Knockoffs.

 

[DSM_PWR]

lOOks like the pacesetter but thicker material...

 

[cheap90gsx]

beefy collector, much stronger then mine.

 

[kawboy]

You are correct, it does infact look like a pacesetter

Does anyone happen to own one of these?

Hows the performance on this style manifold (With the cracking issues associated with the pace-setter aside)

 

[1gDSM4g63]

If you're staying with a Mitsubishi housing just go with the FP Race manifold. Pacesetter is garbage, you got to go with DNP, Punishment Racing, Straight Line, Shearer, JH Racing or any other pro fabricators if you want the real deal on tubulars.

 

[kawboy]

Thanks but this thread isn't about my personal manifold decision.. I already have my own personal opinions on some brands you mentioned.

It's about this particular manifold and its performance, ONLY.

I have a pacesetter and its not garbage. Its never cracked and its worked great. Its jet coated maybe that helps.

But the fact is that a couple of people got them had bad luck and all of a sudden they are junk. I have to do alot of work to my 91 here soon so its going to go on it. worked great for me. It was nice that I could do a run on the drag strip and come back 15 mins later and the manifold was cool to the touch.

 

[PIMking]

I can say with my Pacesetter (with out logs didnt have link at the time) felt like the car came into boost a little faster but full boar at 3k on a 16g.

 

[1gDSM4g63]

It's just logic, if Pacesetter where good performance and reliability wise then it'd be a very popular manifold. It has been around a long time plus the price basically answered all your question.

Check out the thread; 2G-specific pacesetter turbo manifold any good?

 

[Killa_dsm]

The OBX seems as if the collector is re-enforced with a bracket unlike the pacesetter, which may prevent it from cracking like the pacesetter.

I hate hearing that

That's how the whole holset argument started, "if they're so good then why does no-one use them?"

The Pacesetters arent popular because they have thin mild steel tubing and crappy welds.

The performance aspect is rarely discussed

I'm tired of seeing this bs in every thread i go into.I understand some people want opinions,but not all want peoples comparisons also.They ask one simple question then someone compares the part against another part and starts a whole load of crap.stfu already and get hooked on phonics and learn to analyze threads correctly.Ive been waiting to get that off my chest

Ma dude

 

[DSM_PWR]

While ive never used a pacesetter or ebay manifold i do believe in trying something before you make assumptions...

People would say the same thing about ebay o2 housings...
"Try supporting vendors blah blah blah"...
when in fact the ebay ones work just fine and less than half the price..

I say try it and if/when it works post about it and show people its something worth trying

I can't back this up, but I thought I read somewhere that OBX manifolds have fitment issues. I will try to find the thread. Other than that, this is a much thicker manifold than the other ebay ones. That would explain the higher price.

 

[DSM_PWR]

I also read that about their previous Ram Horn style manifold...

but i remember all you had to do was just a bit of grinding...

 

[joyfil2001]

But honestly for that price I would just buy FP's manifold. I don't get all the hype about tubular manifolds for mitsu turbos. The 2g manifold ported flows well enough for just about any set-up.

 

[1gDSM4g63]

Yeah, even though FP manifold are cast iron the runners are wide, short and equal lengths to support higher flow and minimal spool time. It's the best of both worlds and it's very reliable and a cheap price.

 

[jking29]

My bet is that as long as the welds are good, it will hold up fine. The manifold that the OP linked to is made from 321 stainless and not from cheap 304 stainless.

 

[kawboy]

I'm not really concerned about how it will hold up

I've used the Xo2 (ebay) tubular manifold before (It's 321) and its held up fine with no cracking

Mainly concerned with the manifold from a performance standpoint.

I'm wondering if there's any real flow data out there of mitsu flanged tubular manifolds.

 

[DSM_PWR]

Not really...

You might find one or two about the FP Race Mani or Shearer Mani but not many

You'll come to find that most vendors (which im sorry to say)
Dont test their products with flow benches/dynos/etc before releasing products...
I found this out when reasearching for an Intake Manifold and only helpful threads were from people who actually owned more than 1 SMIM

 

[1gDSM4g63]

It really depends on what turbo you got to base it on a performance standpoint. Not to mention, the engine's CFM rating counts too because it really doesn't matter on how well the manifold flows if the head is bottlenecking the flow. Hence you rarely see stock flange tubular manifolds because they're usually smaller turbos with very restrictive housings where bottlenecking might occur if tubular manifold overcapaciated it. Whereas you can often find tubular t3 and t4 manifolds because they're much bigger and have less restrictive housings.

Turbo, Head, etc aside..

How each one flows is equally important, indepent of other variables. I'd like to see some kind of data based on collector design (downfiring, crossfiring, "pyramid" dividers, undivided, etc), primary size and shape in relation to flow and spool, and overall design.

The FP race is currently the most popular mitsu manifold because: A) FP provided some amount of research to help sell it B) Its very unlikely to crack C) There aren't many, if any, other reasonably priced Mitsu manifolds on the market.

But that still doesn't mean that there aren't better performance mitsu flanged manifolds on the market. It simply means that most tubulars (Pacesetter, DNP, etc) are unreliable (quality) and untested (performance).

I wouldn't say DNP is unreliable.. i had one on my old DSM and it worked great, very fast spooling and lasted a very long time...

There's a Reason the Cast Manifold FP sells is top notch compared to Tubular DNP.. and that's pretty much self explanatory



Bottom line...
The Manifold in the 1st post has the same designed commonly seen and has proven to work and work well...

Just as you see the same design from different vendors.. The name/quality is all your paying for...

 

[kawboy]

I wouldn't exactly say the DNP is proven to work well

The collector on them is garbage.
