turbo manifold?

[madcowvert]

what do you guys think about this manifold for $60.. rb25det

do you think it's worth it and if i use this manifold will it still clear the A M performance down/dump pipe?

[Chaos the Xile]

It just looking weak, porly manufactured. If you are gonna upgrade your stuff man, buy quality parts to ensure the longevity of your engine. Cheapies like taht usually don't last long and can casue more harm that good.

[Joe]

$60 lol

you get what you pay for.

[rb240det]

That's the same style I have on my RB20...but I paid a bit more than $60. I dunno...I've never had a problem with mine as far as clearance of cracking, such as other ppl have experienced. Maybe I just got a freak manifold that was actually fabricated decently.

[jobestudios]

Why do you feel the need for it? Either keep the tried and true OEM manifold or spend the money and get a reputable brand that researches and develops their product instead of just makin it look like a racecar part.

[themadscientist]

looks like one of those el-cheapo taiwanese jobs.

[minivan_don]

its an ssac mani painted ... hopefully something hi-temp

By the look of the rust peaking thru the paint I highly doubt it. TRASH, forget that you ever consitered that.

Why is everyone so quick to bash these manifolds? They will flow better than stock (at least cylinder 4 and 6 runners don't point at each other). If it cracks, you're out $60. And no, it will not cause "harm" to the engine; why would it?

Fitment however is not guaranteed with the AM downpipe. You'll have to apply trial and error to that perdicament.

My advice however is to try to find this manifold.

This is also an "SS Autocrap" manifold, and can be had for around a bill. It's designed significantly better than the manifold in question. Fewer collectors means higher exhaust gas velocity. Also this manifold does not choke itself by using the same sized piping after all 3 runners merge.

sloppy welding has resulted in slag being sucked into at least one very expensive turbo that I know of. I am not so cavalier about pulling my manifold off repeatedly to have cracks welded it up. It takes time and money, fasteners break gaskets rip welding costs money and downtime is what it is to the user. "it's just $60" doesn't capture the real costs of the crappy manifolds BS over the long term. And that is if something truly ****ed up happens like a slag ingestion or the turbo just falling the **** off which I have also heard about. Think about you turbo falling off at 6000 rpms, like that feeling in your stomach? No thanks, OEM or quality manifold for me.

[JerryRigRB240]

I have also heard of this slag being sucked into a turbo but I've never seen it. I looked inside my manifold to find no slag, even where the welds were not smoothed.

Every thread I find about these manifolds contains a lot of speculation and bashing, yet rarely backs up these claims. In fact nearly every time someone chimes in with a "I've been running that manifold for a year with no problems". If it cracks, why can't you just junk it instead of spend more money to get it fixed?

That's fine that you want something that you think is more quality, maybe you're not a betting man. All I'm saying is there's a good chance this manifold will serve it's purpose w/o any problems.

[matafied]

Nicely said, I also am trying an ssac manifold. But because of all the talk I just went back over all the welds and then reinforced it a little just to play it safe. I’ll be sure and warn anyone if my turbo becomes detached or becomes victim to any random slag that I missed.

[madcowvert]

ok so stock i will stay until its time to upgrade.

[Sil240]

Don't know about that new one,But I have the old one and it doesn't fit perfectly, You can't really bolt down all the nuts, so I had to bash one runner a little bit.There was random shyt floating around it, I didn't check all throught the mani though.So I'm hoping I don't fall prey to it killing my turbo.

Does that new one put the turbo in the stock position??

Just remember you get what you pay for.Me personally I'm put it on because I got it for soo cheap. And I'm eventually going to change it when I upgrade the turbo.

I'm not gonna buy a $1200 mani, I might buy one of those Greddy or Blitz or HKS turbo kits where it has everything. Dunno broke right now so i haven't looked into it.

Been there done that. It was a huge pain in the azz, car never ran to it's fullest with the leaks.

[Bluefire]

The real question is, does the manifold actually increase power. I speculate minimal to none. And if thats the case i would rather have the manifold that is guaranteed not to crack or have fitment problems...

-Bluefire

[Joe]

this is a prime example of my favorite saying

cheap, reliable, fast. you can only have 2, never the 3rd.

this is cheap and fast. thats why you have to replace the manifold WHEN it cracks.

do it right the first time, or dont do it at all.

[JerryRigRB240]

You definately speculate wrong. These manifolds, especially the one I posted, will gain dependent on accompanying mods. Even with stock power you will see a decrease in boost lag and a little more power.

Kamin, isn't cheap reliable and fast what EVERYONE in this forum is trying for? If not wouldn't we just buy an imported Skyline, a Corvette, Viper, maybe even a Porsche. The fact is most of us ARE cheap. Most RB guys won't spend over $10K on their cars... are you calling that expensive?

We want something fast, and reliable which is why we chose Nissan and the bulletproof RB.

Like I said before, there's plenty of speculation and rumor, but nothing to back it up. If you're going to bash something give proof, otherwise opinions are like ***holes...

In that case I would like to hear your argument on how this manifold reduces lag and increases power.

-Bluefire

[JerryRigRB240]

It reduces lag because it retains higher exhaust gas velocity.

The runners have greater centerline radius decreasing resistance and also retaining higher EGV. Fewer merges also means higher EGV. Also these manifolds do not point the runners at each other in the collectors, like the OEM one does on cylinder 4 and 6, choking itself. This is based of basic thermal and fluid dynamics theories.

Now since you think this is an "arguement" I'd like to hear why you think these manifolds will not reduce lag or increase power.

[240z4u]

I would absolutely love to see before and after dyno numbers on one of these manifolds!

[themadscientist]

That would be very good to see. If you get one of these cheesy things and are willing please dyno the car before and after to see what you get. I would be curious to know if it flows better before it self destructs.

[Sil240]

Well from the looks of the new SS autocrap mani, it definetly looks better than mine.(The old one)
