Hi all have extra bits on my 85 300D on the turbo itself I am wondering what the hell do they do and can I get rid of them? And yes I already have plans in the work to get rid of the awful ox trap!

Lots of federal cars in junkyards. Its just a parts swap away.

Yeah but doesn't that mean changing intake manifold and exhaust manifold not just the turbo? I really like the intake and air cleaner setup.

The turbo doesn't need to be replaced at all. You'll have to change the manifolds to get rid of the trapox. There is no reason you can't keep the air cleaner setup with minimal modifications to the rubber tube.

EGR can be removed and blanked off. ARV cannot be removed as it's part of the turbo casting but you can block the vacuum line and it won't do any harm left that way. The vacuum controls that sit on the left inner fender can also be removed – they operate EGR and ARV so you won't need them any longer. That also simplifies the vacuum system and removes several opportunities for leaks.

There's a guy on the forum who can build you a "test pipe" to replace the trap catalyst. Do all that and you'll be good to go – you get to keep your existing manifolds and air cleaner and the engine is effectively "Federal."
