OBX t3/t4 exhaust manifold rb25

[krayton]

FINALLY, a manifold that puts the turbo where its suppose to be. Also a true 3 bolt wastegate...

says it has a warrenty on manufacturer defects. wonder if they will cover that

[goofynick6]

3 bolt wastegate? That thing isn't even flanged for a T3 like it says...it has a t25 flange and a 4 bolt wastegate....wtf?

[fly240]

you are right, it doesn't look like a t3 flange. I don't know what it is, but it doesn't look like a standard t3.....

[SillyRB]

Why put a $2xx manifold on a car / motor you have spend alot of money, sweat, and blood on. Its not worth it breaking abd a piece go into your turbo or motor, and so on.

My guess, first guy to buy it will break it ! if under any stress

[Sil240]

I think that hilarious there making manifolds with T25 flanges. I hope no one will buy one because there gonna get a great surprise when they find out that they have to down grade there turbo

[Imissmyturbo]

Doesn't matter how good that manifold is made It looks as if it will go right into the steering shaft.

I am confused both by what the listing says and by what people have said in this thread.

What I see is a 3-bolt T3 turbine OUTLET flange where a 4-bolt T3 turbine inlet flange should be. And that 4-bolt flange can only be for the wastegate... unless a complete idiot designed the manifold. But who makes a 4-bolt wastegate?

So what it looks like to me is a nice manifold onto which someone welded completely incorrect flanges. Someone should buy this, cut off the 3-bolt flange and put a T3 inlet flange on there and cut off the 4-bolt flange and put a standard wastegate flange on there. Or you could ditch the wastegate altogether and go internal, thereby avoiding the steering column problem.

Overall, I'd say it's a nice manifold. Nice welds, thick flanges, and good reinforcement. And btw, OBX does not make anything themselves... they just rebrand stuff. Their stuff is definitely not top-of-the-line, but neither is it junk.

HKS wastegates are 4 bolt.

For the 3 bolt, I was totally confusing it with a 3 bolt compressor outlet on a t25 type turbo as pictured here:http://linux.forcedperformance...l.jpg

Anyway...very incorrect turbo flange.

didnt learn from the first go around on the cheap manifold huh?

The 3 bolt flange looks like it's for a Greddy Turbo. They run those kinda flanges on there turbo's.

[T4 RB25det]

But who makes a 4-bolt wastegate?

hks, greddy, tial, deltagate, turbosmart

greddy makes alot of 3 bolt turbos, the t3/t67 variation they make comes in a 3 bolt, but i dont know of any other t3 that would come with 3 bolt?

OBX used to be a ****ty company, they made crap parts for hondas, but then they were bought out by somone who pretty much stoped making thier own products and started to buy other companys products. thier limited slip was just a kazz, thier intercoolers and turbo kits were greddy. so this could be a greddy manifold hence the 3 bolt flange

i am not too fond of the low mount mani, there are not too many gains as far as power goes for the top mount, but the install and maint. on the top mount is 100X easier.

their LSD was NOT a Kaaz(clutch). its a COPY of a Quaife(helical) LSD. i can show you the huge differences between an OBX and the quaife in FWD applications, its a ****ty copy at that. people have had nothing but huge problems with them. transmission destroying problems. there are TONS of threads on this.

if you want to go fast, you have to spend the money. period.

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

[T4 RB25det]

sorry i spaced out on the name, it was the quaife copy not kazz. not too many people had problems with them honestly, as long as you took it apart and torqued everything down within spec before you installed it. i ran one on my old turbo gsr and it stood up to 30+ drag launches with slicks and 534whp. never had a problem with it. the new owner of the car still is using it with no problems

alot of people are scared to test out obx probucts due to thier crappy reputation. the only thing i ever use of thiers was the limted slip so i cant say for sure how good thier other things are and i have never heard of anyone testing a manifold out so it could very well be just like ss autochrome.

[Joe]

you shouldnt have to reassemble a differential BEFORE you install it. thats horrible quality control. and i still know people who have had issues with axle removal even after proper install. you get what you pay for, and when installing something that is an intergal part of the drivetrain (differential) you shouldnt cheap out.

[240sxed]

Another retarded ebay filler product. Ebay is gettin ****ing annoying with these cheap copies. And this one in particular isn't even a cheap copy its just a ****ed up cheap manifold, not copying anyone.

[krayton]

id try it if they gave me the manifold, turbo and wastegate for it

...and a coke. cause im thirsty

[Nameless EJ6]

Not fond of the wastegate location. I've never liked seeing wastegates being located like that.

[240sxed]

B/c of space constraints, i'd rather have an internally wastgated turbo, provided itdoesn't creep, but you can always port.
