are they around still?

I understand there are/were 2 different 200tdi manifolds. Disco/RRC and Defender.
Avaialability? Not sure and not worried. A 300tdi manifold could be chopped and a flange welded on likely for less coin than a good 200tdi manifold.

You can buy manifolds for lots of different engines,the boy racers use them and I don't think it would be that hard to mod one for the Tdi,there is lots of styles available. Pat

I love the price, simplicity and reliability of a non VGT ball bearing turbo, it looks to make good improvements in torques and power , but the manifold?

The manifold availability is one of the big deciders for a Tdi upgrade, we don't have much choice there. I suspect those dyno results are few years old, I spoke to a few guys and they said someone used to make the manifolds, they even rung around for me, but nothing came up.

I don't think the TD04 is used with he landrover manifold, everyone spoke to said the landy manifold is a large part of the problem on the Tdi.

cheers simmo

MTQ have a 300Tdi manifold available, (it uses the numbers 1 and 4 300Tdi 'bullhorns' with a newly cast centre section) but personally I'd go a 200Tdi Disco one, as Bruce Davis uses for his Garrett upgrade.

I have pics of the Bruce Davis setup if anyone wants to see.

Yes please

Excuse the quality, this was taken years ago with an old Nokia phone in a mates workshop and uploaded to another thread a while back.

Think I have a few more filed away somewhere from different angles.

This was fitted to a 300Tdi in a 130CC that does farm duty on one of the studs here.
BD use their own cast dump pipe to mate up to the standard 300Tdi exhaust, and the intake piping is just tweaked and extended IIRC.

Any idea how the wastegate works? Doesn't look any easier to access than original, same goes the exhaust flange. I ended up just replacing mine with a new stock one but wish I explored options a bit, if only for the sake of curiosity.
Edit ; Not a great choice of words, we all know HOW it works, just cant see it

It's the same as stock, the turbo is a T250 with a T25 exhaust housing and the wheel/s changed.
I was told once what they were, can't remember as I wasn't that interested !
