R34 Gtr Turbo Manifolds - Difference Between Stock + Nur / N1?

[iwanta34gtr]

Hi All,

Curious if there is a difference between stock R34 GTR and R34 Nur / N1 GTR turbo manifolds?

I have attached a photo of the manifolds removed from R34 GTR Vspec II Nur.

Appreciate your advice.

Thanks.

I believe the single flange is a little more open than the stockers. No big deal either way, grind it out to gasket size and do the turbine housings while the turbos are off. All possible differences are taken care of

Thanks for the quick reply mate. I just bought -9 turbo's and these came with them.

Didn't know whether there actually was a difference between Nur / stock, and whether for my plans I should just stick with my stock ones.

Only aiming for ~300KW @ wheels, from pictures - it looks like there is a difference, almost as though they'd been ported from factory?

Upon research I didnt know if using them would kill response?

The smaller flanges would increase the exhaust velocity, improving spool slightly. Not like you need them ported for that power range either.

Just use whatever you have, you really won't notice a tangible difference either way.

As above, just run what you have... I'd doubt you could measure the difference at 300 kW.

As a side note, I ran 400kw with unported stock manifolds.

... I'm still of the opinion that there are at least 4 variations of stock rb26 exh manifolds.

Thanks everyone for the advice, appreciate it.

Hi guys,

Any rough idea on what a set of R34 GTR N1 / Nur turbo manifolds are worth?

They don't appear to pop up for sale very often so its hard to get a price guide.

CRD advised to port the stock manifolds to same spec it would cost ~$800.

Thanks in advance for your help.

for $800 you can buy a compressor and die grinder with bits and still have change and its more tools for other uses

I, like Paul, ground out the stock manifolds, more for less turbulence then out right flow

do they gold plate them while they are at it? $800 is f**king ridiculous

[R31Nismoid]

$800 is a bit rich I agree.

Seriously, just put the manifolds you have back on. At the requirements/power you are after you ain't needing to waste money on anything like that.

[GTRsean]

They are that easy to port match, I still have a spare ported set hanging in the shed lol. Not even worth selling!

[SiR_RB]

Yeh I second that

Put the nur manifolds back on, will be more then enough

I ran 360kw with stock non ported manifolds

[iwanta34gtr]

Thanks guys, yes I will be putting my stock GTR manifolds back on.

The N1 manifolds in the pictures are others I obtained as part of a package with my replacement turbo setup.

As I will not be using them, I was curious more so on what they would be worth - thinking about selling them to recoup some of the cash I've spent.

Cheers for your help.

Elaborate..
