This Manifold Vs Stock

[B0oStEr]

This style of manifold seems to be available all over the place.

Are some better quality than others?

Most are ss304 are they available in ss321?

Has anyone fitted one of these?

How effective would one be with a 2530 or a highflow?

[Cubes]

2530, don't waste the money on a manifold. The stock item is well up to the task for that power level.

well and truly 2nd'd

and a 3rd

[lukits01]

Then when should you ever consider using a manifold like this?

Is there an advantage of using it at all?

[R31Nismoid]

when you get over 300rwkw i'd think about it.

the money can be better spent elsewhere below that IMO.

lots of 2nd'ing happening in here

and 3rdy

[Cubes]

I fourth the secondy.

I say a good manifold is never a waste because it can always be beneficial down the track which most of us seem to go down these days. However, like others have said, another manifold is not needed and THAT manifold you have shown us I would NEVER touch. What a piece of crap. If you get an aftermarket manifold, Id never go for anything less than equal-length runners... and that crappy manifold you have a pic of has three runners collecting into one runner far before the collecting flange. A big no-no (it create hot spots and associated irregular thermal expansion*) if you dont want your manifold to crack, especially in this case being stainless steel.

I know of one person who has blew a hole in one of the above cheapo manifolds at a track day.

[AzzurrA]

have a look at the manifolds that 6boost offers... have heard some good things about them (i.e. decent quality and the guy has actually put some research into the design of them)

[Slide]

Another + for Kyle at 6boost

He makes awesome quality manifolds.

[rb26s13]

never been a fan of those ugly manifolds

[R31Nismoid]

can you honestly say its the best way to spend $1200? regardless of the quality and the (if any) gain your going to get?

Its cost vs gain, and quite simply for the money there are far better (and proven) things to spend that money on.

[AzzurrA]

i would only buy a manifold like these if i was chasing BIG horsepower (or i had LOTS of money to throw around at useless stuff)

[r33_racer]

2nd or 3rd for kyles manifolds. Very nice work.

I have to disagree with this statement anything over 250rwkw and wanting 300+ u should change the manifold...i dont know where everyone gets this idea from where the standard is fine up untill 300 ive tried the standard with my r34 and it was choking at 250 and boost was not holding all the way to 8000rpm droped off at 6500 with a 2835!...

Changed the manifold and bang! more power everywhere and held boost!

did i just enter a shit fight..ahahah

[Cubes]

infected flow,

nar no shit fight...

The stock manifold tends to 'really' hit a brick wall at around if not slightly before 300rwkw.

But as you said... good gains can be had earlier. The crappy china manifold the op is comparing to shiet and worth while sticking with the stock manifold.

What manifold did you go with out of curiosity?

I've seen more cars make over 250rwkw on a stock manifold to suggest that its not essential.

One of them is a NEO motor to boot. Even if 8000rpm on stock bolts is a bit dangerous

I'd think you had and issue somewhere else, and by changing the manifold, the issues was indirectly fixed from the following.

Exhaust size/flow

Int gate flow issues, or related bad dump design choking it

Poor boost control or otherwise.

There is a lot associated with a dropoff, and the manifold is often blamed incorrectly in some cases. Not all.

Just my thoughts.
