obx tubular manifold

[BigRand]

Okay so I'm just wanting the person or peoples that buy this to post there findings about this manifold here. (maybe it should be in the bolt on section for new people).

also want to how this "lifetime" warranty thing is going to work out.

Go OBX!

Well here's a quote off 2gnt

I also notice that there was a bottom mount "Ramhorn" design also for a bit more.

Looks pretty tempting.

Besides the poor fitment, I suspect that much of the manifold's shortcomings lay in the metal used to make it. Good quality stainless is extremely expensive to buy and weld. If they were using the good stuff, it the raw material would cost $300 alone...

I was thinking about buying one, maybe I should do a write up on the product. I have the extra cash so if it falls apart its cool. Before I bought my Greddy header when I was still NT I had an OBX and I was pretty happy with it. So I think I am going to give the one rand pointed out a shot. I will prob order it after Christmas if there still around Ebay. I do not think the Ram style would fit very well and would have more fitment issues around the Frame Support and Coolant lines.

Manifold doesn't look too bad. I hope someone can test it out for us first.

You guys keep bringing up the strength factor of the welds. Let's not forget you STILL can improve the manifold, even if it didn't come from the manufacturer that way. In laymens terms, if the welds look weak, spot weld them for extra support. You basically modify the part before installation.

My manifold looked weak but I had a buddy spot weld everything and anything for extra support. Worth the extra metal IMO...

Nija- You da man! Go for it buddy!

Just to let everyone know we will be test fitting both manifolds from obx on our shop car, we will take pictures and will be reporting our finding both on this forum and to OBX, seems sofar that both designs look good but dont seem to have been test fitted to anything prior to being manufactured, the ram horn looks the most promising but we dont see how the external gate flange will clear the radiator, as far as warranties go from OBX we havent had any trouble retuning manifolds as long as they havent been tampered with (egt drilling, welding, etc)

Do it and ceramic coat it too! A soon as I saw this one for the 420a I called Rand, but I haven't been in this part of the forum for awhile and he told me he started this thread a week or so ago, so I am here to check it out too. Looks nice, but spot welds and some ceramic/ Jet hot coating would do it some good to... Get it Ninjai!!! DO IT! Finally good to see a nice tubular manifold being made for the 420!

[cimotorsports]

We were also thinking about casting a stainless tubular manifold for the 420a since most other tubular manifolds are complete s**t, we have a few of the OBX ones on the way for test fitments and so forth and well try and get the picts up on here asap for everyone to review, i knew that one manifold wasnt going to fit first time i layed eyes on it as hybridrst pointed out , overall a good idea but OBX always seems to fall short on their products since they are all made in CHINA, hell im not even sure why we sell OBX anymore We need a good solid tubular manifold case closed

Just an update on my situation. Since the 98 is being auctioned off with my stuff in it (not the turbo stuff), I decided to test some more things out. The Star Replica manifold is still good, it hasn't been beat on but now its just sitting in the shop waiting to be installed onto the new car. But Since this top mount has the ability to mount up to T3 and T4 turbo's and I have plenty of both, I'll order one just to screw around with. I might even set this up on one of my customer's cars just for the fact that people are having trouble fiting it with the hood... I just sold him an Evo CF hood so it should have room. I'll let you guys know when I order it, look for one of my posts in the near future.

i will be trying it out very soon and do a write-up on it for everyone.
i will be putting a 35r with a completely build motor including long rod kit p and p head with fully built top end. so results coming soon.

I hope you haven't bought it yet because the manifold doesn't fit. It hits the thermostat housing.

Time to whip out the Dremel!

It's pretty straightforward. If the part fails, they come round and kill you. That way, you won't be able to warn others.

I almost fell out of my chair laughing when I read that. I don't know why.

i was already told this by concept illusions so i think i will be coming up with a CNC'd t-stat so it fits. or modify the existing one i will have to see how off the clearances are. i will also be adding a few more supports to the manifold.

Might as well make your own manifold if you are going to put that much effort into making something work IMO.

[knightrider4]

not everyone can make there own manifold or afford to get a custom one made. So if i can R&D to benefit the community than i will do so. we will see how it holds up. if it doesnt than we will go from there. i can get the cnc'ing done locally through a place we out source to at my shop. so if i need to i can mass produce them if necessary. My only issue with the manifold is the collector needs to be cleaned up a lil bit, but other than that the welds look good so we will see.

[VelocitàPaola]

There's already at least three company's currently putting in the time for R&D for a new manifold... there's no use in spending so much money retrofitting an inferior manifold; OBX should've designed it right the first time. A custom thermostat housing is a ridiculous solution for a poor fitting manifold.
