Stainless Manifolds???

[600hp]

in that case you don't have the money for less lag as a good set of manilolds is about eh same money. i would just the cam gear and get Jim from croydons to give it a tune.

ive got a low mount ss manifold with gcg hi flow turbo , it gave me an extra 12rwkws at the same boost, and allowed me to run more boost pwer went up 20rwkws.

[Baz]

A question, what makes the difference between a low mount exhaust manifold and a high mount manifold? Does it disapate heat easier? Does it allow more room to fit larger turbos in? Does it provide a shorter route?

What is the main difference between the two?

[Waldo]

The high mount ones are so you can fit larger turbos under your hood but im pretty sure that the new GT30 rb20/25 bolt-on job can still fit on the stocko manifold and thats a pretty big turbo for an RB20

[muaythailuke]

Is this one of the manifolds in question? So what is the verdict on this item, is it worth spending the $400 for one, or better off waiting and saving for a tuned length one for around $1200

[bigcarl]

thats the one ive got , it gave me an extra 12rwkws at the same boost.

Guys

I've discovered these Jap GTR manifolds - anyone interested in a group buy?

anyone interested in a group buy?

Depending on Price and when you were thinking of getting them in...

I have been looking at some of those beig sold by another guy on Yahoo Japan.. his "Buy now" price is 50,000 Yen though.. Which through 'pp-oz' buying them off of Yahoo Japan for me, works out to be about $900 delivered to my door..

What sort of price to get these landed and delivered in Aus?

Also interested in Rear Adjustable Upper Control Arms and Engine Dampeners to suit an R32 GTR if you are keen on going a bit bigger with the buy up..

[WazR32GTSt]

thats the one ive got , it gave me an extra 12rwkws at the same boost.

as in the same turbo, same set-up, only difference was the changing to this manifold?

it would make sense that some sort of manifold would flow better than the stocker... just look at the stupid stock thing...?! its like getting extractors on an NA car i suppose...

has anyone tried an aftermarket manifold with the stock turbo?

[7heavn]

I'd be interested in a group buy for GTR manifolds let me know if you guys decided to do something .

[DAN00H]

the manifolds I listed above should come in between $620 - $680.

I'll confirm it all today. I am also looking at getting the HKS style dumps off the turbos.

[Yorik]

At that price I am in if we are looking at doing this relatively soon. (ie. Next month or two.) I got confirmation last night that these SECTION manifolds mount in the stock position, I have also seen some people weld a few sections of metal onto them so that they can mount the stock heat shield over the top, I am looking into this now for mine. As well as Ceramic Coating.. (But I am pedantic when it coems to these things)

I will keep my eye on this thread, if you start another one, please reference it in here.

In terms of dump pipes I am looking at the Trust ones as the feed for the wastegate pipe is a lot further down, you ahve to buy them as a dump/front combination, but the fruther down the collection point the less restriction and potential turbulence issues you will get up near the turbine..

[Beer Baron]

if you can win some at the 32000yen they are currently at I would be interested too. even up to around 40000yen.

don't forget you'll have to pay someone to buy and ship them and they won't be particularly cheap to post (quite heavy/bulky), plus factor in some import duty + GST for good measure.

[Yorik]

Hence the reason why it was going to cost $900 to get them here for 50,000 Yen sale price over there.. That quote was through pp-oz, who are offering a Yahoo Japan proxy service..

[DAN00H]

the stuff I have bought so far has been well priced

york, Yeah, I have seen the trust FP, but I alreay have a nice set that I don't want to get rid of. Hence the reason I'm looking for some short HKS style units - better than the factory units!

[Gav]

Sort of on the same topic, does anyone know of a cheaper version of the bridged low mount manifiolds?

My GT-RS terbs shuffle like a bastard during boost build up and I have the option of either adding a bridge to my existing manifolds (prefer not to as they are nicely ceramic coated inside and out) or selling them to buy a bridged pair.

[Beer Baron]

Gav mate,

do you just mean a metal bracket to brace the two together or an actual tube that will join the exhaust gas from the two manis?

I'm going to assume you mean bracket, in which case I reckon you are better off adding one to the manifolds you have.

[Gav]

Yer digger - that be the one. The HKS variety seem to use a "bellows" type of bridging pipe that presumable gives a little bit of play. I would imagine this would help ensure good fitting of the manifold against the head?

[Gav]

This shows the manifold that I'm talking about.

It appears that the std pipe (with the "Twin Turbo" badge) won't fit and you require some aftermarket or custom pipes from the terbs to the IC.

Anyone with experience of these?

[Yorik]

Anyone wishing to organise a gorup buy on the turbo outlet pipes like the picture above, I am keen.. I know the stokcer pipes are majorly restrictive..

The crossover pipes are a good idea to equalise turbine pressure, but I always have a concern about any possible reversion causing turbulence, but this would be at certian rev ranges only and if you're trying to run GT-RS's then I gues you need all the help you can get..
