Manifold Is Cracked On My Stagea 96 Rb25Det

[Stagea1]

Hi guys. I had my dump pipe upgraded to 3" and they found a crack on my manifold. Does anyone have connections to a new one? Or is welding better for now? Not many stageas around my way. Any help would be appreciated. I heard stainless ones aren't that great. Is that true?

Where are you?

What kind of Stagea you got?

The more info you give the better the help you get

*EDIT* My bad just read the rest of your thread title

you can pick up a 2nd hand manifold for around 50 bucks. they wroth nothing, even if you opt for a low mount from ebay they around 200-300. better than a cracked one.

and the rest depends on how good you are at bolting the thing up.

from what i know any Rb20/25 exhaust manifold should fit.

Hey sorry mate ye it's 1996 stagea with the rb25det. Where are the $50 ones? And is that a stock one? I've looked on eBay but I'm not too sure on them. Are the stainless Ones k? I'd get my mechanic to install it. I haven't got time or tools to do it. I'm in Victoria.

[Stagea1]

Also I've been told that the bolt on ones don't always "bolt on"

Stainless manifolds (especially cheap ones) are more prone to cracking than the factory standard cast items, so unless you are trying to get every last kW out of your car I'd just try and source a standard one.

I recently cracked and replaced the manifold on my R33, it's a little fiddly but easy enough to do. Just be prepared to have snapped manifold studs drilled out

[Stagea1]

Yep I've been told about the studs so that's cool. I am trying to get stock replacement but it's tough. My mechanic said might be able to weld it up and make it better. So that might be ok.

[Stagea1]

Hey my stagea does choke up when I floor it. Abit of lag. Would the small crack be the cause?

[GoldZilla]

Cracked manifolds and broken manifold studs are a common problem on all RB20s and RB25s, unfortunately...

[Stagea1]

hey so any connections for a stock replacement?

[wolverine]

2nd hand RB manifolds are cheap and dime a dozen, stick and advert in wanted to buy section.

[horrace]

put up a wanted to buy mate heaps of people have them lying around to sell for a carton, there is one on ebay but they want 200 dollars LOL dont think so.

[66yostagea]

If you break some studs on removal you can get guys who can drill them out with LH drills without having to remove anything else.

[Stagea1]

oh ok. thanks for the help guys. im new to the forum. il be sure to advert.

[RS4-S]

hey mate, just cos i didnt see it mentioned they are the same as an R33 GTS-T so thats why they are a dime a dozen, dont go looking for stagea specific ones cos your wasting your time

$30.

[Stagea1]

thanks brother. appreciate it.

Possibly, I picked up a little response when I replaced my manifold. I mean the more exhaust gasses leaking through the manifold, the less exhaust gasses that flow through the turbo to force more air in on the intake side.

That, and I imagine any exhaust gasses that are leaking before the O2 sensor would cause the ECU to not run as well as it possibly can

[Stagea1]

Sick as. Thanks for the info. Sau is awesome. I've found several I'm looking to buy n waiting to hear back from. I had it booked in to be welded next week but won't be doing that as I'd rather a replacement. Thanks guys

[Bronx]

or if you want to do it a cheap way you can use a normal welder to just weld over that crack...... dont know how long that will hold since its steel weld on a cast iron manifold, but some people have done so and its been ok for years. (would advise against this though)

so i guess my estimate for 50 was a bit over the top eh??? seems like they exist cheaper
