Exhaust manifold from ebay

[K Simmonds]

So its an £80 version of an RS Spec manifold that needs some grinding?
Sounds like a no brainer to me

Yeah that about sums it up, these's manifolds are a direct copy of the Wager RS2 Evo item... I have a genuine one of those and there's little difference other than the rough casting.

WHat type of die grinder bit did you use?

[Dobby84]

Well I've got the 3b manifold off and taken some pics of the two together.

Will there be an issue using an RS2 turbo to manifold gasket with my current turbo as the 3B on has a raised spigot rather than a flat face?

Need to try and get the studs out of the old manifold unless someone can point me in the direction of new ones?

Could you use standard high temp bolting rather than studs for the wastegate?

Do you want air or electric?

If you can't get the old studs out, I just bought a length of high tensile studding and cut my own.

I've got myself an a new compressor now and a die grinder so that bits sorted.

It might be the picture, but the ports on the ebay special look smaller then the 3B?

[mike74]

i was just thinking that too! strange...

[Dobby84]

Pretty sure they are the same and its just the photo angles but I will measure the ports at lunchtime.

[Dobby84]

Measured both manifolds and they are the same, must have been the photo angle.

Interesting. Looks like more quality than china manifolds, not bad priced if good quality, but why they use that cheap square head flange..?

Shouldn't the ports be bigger than 3b? Since Rs2 or, in this case, Wagner copy...

And if not, isn't that much of the reason why go towards Rs2 or Wagner, more flow?

Or the main reason the design for ports #1 and #5 that creates back pressure on exhaust valves for those cylinders?

I'm pondering buying one of those, but on this side the pond I can only source Rs2 copies, not the one you got which is a Wagner copy. I wanted to go Wagner since they seem more sturdy and are supposed to have more flow than Rs2 also. If the flow ports aren't bigger... Might as well get an Rs2 copy from the US.

My knowledge of the more technical side of things is rather limited when it comes to flow but Im sure someone here will provide an answer soon enough.
