Hi
In response to a request we have had, we are offering some stainless steel Nissan S14 Manifolds in a group buy.
These are 304 SS, thick wall, mandrel bent, TIG welded etc.
Very nice quality. We have sold quite a few of these to SX owners and they have been very pleased.
Picture:

Obviously it is up to you to remove the SR20 flange and weld on a T16 flange!

Individual price is £150 + £15 delivery
5+ price is £135 + £10 delivery
10+ price is £130 + £10 delivery.

Cut off will be Christmas Eve (24th December), with payment due by 10th January at latest.
Delivery will be approximately 3 weeks later.
We can move the group buy forward if everyone pays early...

Please put your names below

is this a good fit after the t16 flange is welded on? or is it a move everything around type of affair? sorry if it's already been explained elsewhere :) thanks Anthony

As far as im aware its a good fit, think someone mentioned the turbo sits at a slightly different angle tho....
Im sure someone mentioned it in the flange group buy post.

Just to point out - we are offering the parts here, not a guarantee you will get the result you want!
That's down to you / your fabricator.
Cheers

The manifolds will not fit out of the box, you need to alter the pipe spacing slightly and cut off the flange and reweld at a suitable angle to mate the turbo.

Looking at the flange I think the port holes are quite big, you may infact be best of putting the pipework through the hole in the flange and welding it on the front and back to give it more strength.

The key thing to consider here is bracing and making sure it will not move anywhere as this is the primary reason why stainless manifolds crack, take a look at any old F1 car and you will see the turbo is braced.

I will be having a full custom manifold created instead of a s14 stainless jobby. This way everything is built to the spec of both the head flange and the turbo flange without any compromise. I know the ones grant has here are mandrel bend 3mm 304 stainless but if people are looking to buy some of the ones off ebay you need to be careful as they are prone to cracking and fatigue after a very short period of time. You can obviously just have the seams welded over but me personally I want something that can remain on the car without any faffing around after the build, for a little while after anyway. ;)

The problem according to reliable sources is the construction of some of these manifolds, where they are using gussets to help support the manifold and turbo weight. In reality is apparent that this has the opposite effect, the manifold tubing obviously expands and contracts causing some movement but the gussets due mostly to poor placement cause fatigue as they are trying to hold the tubing in a static position. Eventually causing cracks around the welds mostly. Another problem with some of them is that they are purely welded sections of tube (unlike mandrel) that have had the weld seams polished out giving inconsistent thickness to the metal, again through fatigue can cause cracks.

Just a little something to consider :)

they might not be as good quality as grants but you could always do what i've done and buy one from ebay, roughly 100 quid.

or you could wait a few months until mines been on the car a while and see if it knackers up. haha

You can buy a stainless manifold for a s14 for £89 off ebay, I was thinking of doing this then taking it into carrick engineering in prestwick and getting them to make me up a flange and weld it all together

Ebay Link
Thats the one I was going to try

How do people find the alignment for the exhaust side of things with one of these?

Can't really see that being a problem as my car is sitting with the manifold off :D

I'll but one next week and see how easy it is, and if its a winner al get a load of them made up for rovertechhers at really good prices :)

I have a manifold sitting in the unit and from what I can see the alignment is quite a bit off and the ports are smaller in diamater so it needs a lot of work for a pukka job.

that manifold on ebay is the exact one i've just bought, and i've got a mild steel flange on the way from grant. i have no idea whether its going to work or not, but i'll keep you guys updated as we go, :)

well, i have my manifold, and looking at it compared to a standard t16 one, its going to be a right cow, the angle on both flanges is different, the head flange its different on one axis, the flange on the turbo is different on 2 axis', the ports dont line up perfectly, and at this point i have no idea if there is enough spring in the stainless to reposition them. also, the distance from head flange to turbo flange is much bigger, so i duno whats going to happen regarding downpipe fitment.

god knows how the AA guys modify these to fit a standard exhaust setup...either way i'll give it a shot, and post some pictures up along the way in a couple of days.

righty, here's a few piccies.

the first 2 show how the angles differ between the flanges, the t16 ones are at 90 degrees to each other

Image

Image

and these 2 show the difference in port size and location, the outside edges of the 2 inner ports are lined up.

Image

Image

i dont have pictures of the difference in height from one end of each of the manifold to the other, or the distance between the flanges which is much bigger on the new one, but as you can see, its going to be a challenge, may require my downpipe modifying, still going to be cheaper than buying one at nearly 500 quid from AAa though.

The flexi joint and the exhaust rubbers should compensate for the change in angle.
