Rb26 Exhaust Manifold Is There A Front And Rear?

[No.96]

G'Day,

I've spent all day bolting up turbos and dumps on my engine and when I went to bolt the inlet to the rear turbo it fouled on the front dump.

The dumps are Chinese so before I abuse the dump supplier I was wondering if the manifolds are different, they look the same.

any feed back would be good

Thanks

hey mate not a definate answer, but did read a post by someone saying they are different, search wud be the go

FAST says they are the same (R32 GTR....I'd be surprised if R33,R34 weren't the same but haven't checked)

Exhaust manifold is the bit that connects the head to the turbo....

Re: dumps, the xforce ones i have are different. You have to hold them together to notice because they look so similar, but one is bent around more tightly than the other, and the wastegate pipe joins the main pipe in a slightly different location. There would be about and inch difference in the location of the front pipe flange, so yeah its looks like you have them on backwards.

You're doing better than me - i still cant get the effing front manifold off. I'm going to try moving the power steering pump - is that what you did?

I'm rebuilding the engine so I am doing on an engine stand. Still a pain in the arse.

The dumps are definately different the longer one goes to the back, I am talking about the manifolds that bolt to the head.

I think these dumps are duds anyone got any HKS's in Adelaide?

Oh ok sorry about that. The second set of manifolds i have appear identical.

Just went and had a look at my spare set of manifolds and they appear the same.

Dumps are definitely different front to rear.
