The 1987 300D has a T3 turbo... totally different turbo, totally different wastegate. The only possible one that might work is from the 1987 190D-T (201.128) with OM602.961 engine.

Well, scratch that idea. I guess I'm back to the replacement wastegate you had been in touch with your vendor about. Let me know if you get one tracked down that has the proper rod length. I suppose I could fab one up as you did, but that means buying a tap & die set to re-thread the rod... I'd rather buy the right length to start. Thanks again!

Keep an eye on ebay, $100 is a lot of money to pay for such a simple device.

You don't have to get an OEM Garrett/Mercedes branded actuator, there is no reason a generic one will not work just as well.

If we could find one that is the correct size, shape, pressure, and mounting... that would be GREAT. So far, I haven't seen any, but I haven't looked real hard either. The cost for the wastegate alone was about $75, btw... but with shipping, and the turbo fitting, the total was about $95.

I would be OK spending $75 if it was "right" from the get-go. Gsxr, was that your jobber price, or a public price?

That was the public price... and I just double-checked, a copy/paste from their email is as follows:

433489-12 is $79.

Looks like my memory was four bucks off - d'oh!

Forgive me for my ignorance, but i'm trying to understand what all needs to be done to do this modification. I have no problem with using my tap and dye set to add some threads, but i'm sort of unclear on what all i'll need to do this modification other than the wastegate/rod combination .

Did the idea of connecting a vacum line to the "test port" rather than drilling and tapping the turbo itself ever pan out ?

Or is it necessary to drill and tap the turbo ?

So basically the only thing i have to change to rid myself of the EGR is to buy this replacement wastegate ?

Do i also need an EGR block off plate ?

This won't interfere with the car's computer ?

Basically, i'm asking for a complete walkthrough/description of this mod .
