Is this a low mount or high mount manifold??

[Bl4cK32]

Which way around? I keep looking at the stud pattern on the manifold, but it looks different (reverse) to what it is on the rb25 head.

More importantly (probably the answer im after) Is it a low mount or high mount??

[R31 POWER]

High mount,I just looked at my manifold and the bolt holes are in the same spots if you know what I mean.

[Roy]

Sorry, my money is its a low mount, it sets the turbo low in the back corner of the engine bay with the wastegate sitting high (and proud!) in the engine bay.

It looks to be part of the old HKS T04 RB20/25 kit, being a cast tubular style manifold.

[DoughBoy]

That's the old cast HKS manifold, as Roy said.

[R31 POWER]

Opps I thought the external gate opening was the flange,my bad.

[Bl4cK32]

so is it any good though? (getting a GT35/40R to sit under it)

wastegate doesn't sit too high does it? going on the RB31DET in the 32 so hopefully i can close the bonnet....

Anyone got any pics of what it looks like setup??

[Bl4cK32]

no one?

From the pic, the turbo will sit onto on the manifold. not under, which might make everything a tight sqeeze down there.

If u can get it cheap the it might be worth it, coz cast stuff like manifolds aint the best.

[Bl4cK32]

1. I agree with what Roy said about it being low mount. It HAS to because of the stud pattern.

2. How much research have you done to come to the conclusion x manifold is better than y manifold?? Please explain....

and there is more room now under the manifold due to the height on the new motor

[Guest INASNT]

Yes its a low mount manifold but the turbo will sit above the manifold, if u r going low mount u r better off the turbo sitting under.

Equal lenght runner made from steam pipe or s/s tube manifolds that go 6-2-1 are the norm

[Bl4cK32]

Sorry abo0ut the stupid question, but how the HELL does a low mount manifold sit a turbo above it????

And equal length runnners and steampipe arn't the be all and end all of manifolds. Its more about how the pipes merge into each other, then into the turbo flange. If you dont know this manifold does go 3,2,1...

[Cubes]

From my research 3,2,1 manifolds are a little better.

INASNT, the top mount is for the wastegate. Have a look at the two runners with the bolt direction different from the other four.

The two that are different go to the rear of the block.

Bl4cK32, have you had the inside de burred/tidied up? It may be worth ceramic coating or wrapping it before it goes on too. Looks like a vast improvement on the stock item, as the gasses are merged rather than slammed into eachother.

If it doesnt fit, just get a hump in the bonnet, or even a raised vent. Would serve a dual purpose that way.

Look where the flange on your manifold. When u bolt the manifold to the head the flange it facing up, so the turbo will bolt on to the flange making the turbo sit ontop of the manifold. Low mount means the turbo is still sitting down beside the head not high above the cam covers.

DOH, i didnt look at the pic that carefully

That manifold doesent look like it will make the turbo sit high enough up to cause any bonnet closing problems

[Steve]

Bl4cK32 is mounting his engine approx 30mm higher than normal;)

Just arrived in Australia Steve but some work will be done to it (heat wrap or coating) the inside looks pretty damn smooth...

A nice hole in the bonnett for the wastegate eh:D

[Bl4cK32]

[Steve]

Yep, and you could mount the screamer pipe so it points to the side:p

so that was a new manifold? if you dont mind, could you pm me the price and where you got it from. I may need to upgrade mine in the future.

[Evo_Lee]

it's obvious a low mount, as mentioned the wastegate on top and split pulse setup ideal for twinscroll turbo
