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?

  • 2 months later...
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..

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?

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..

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.

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.

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.

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..

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
