Decoration. I got bored with the standard smileys...

I see from your pictures the new, but incorrect length actuator, has a part # 433 489-12.

What manufacturer is it from? I would need to locate this in Canada as most web based shops refuse to ship to Canada because of customs issues.

I will try chasing that around!

Thanks,

That should be a standard Garrett part number... any Garrett vendor should be able to order it. I'm still waiting for a p/n with a longer rod.

This is a very interesting thread. Are there any turbo powered cars that can be found at junkyards with a similar pressure actuated wastegates?

i used one from a 98 Jetta TDI .I had to cut off part of the VW mounting bracket drill a couple of 1/4in holes and fabricate a link to connect to the waste gate lever,all simple stuff if you have a vise ,a hacksaw & an electric drill. i took some pictures at the time i did it but have not figured out how to post them. If you are really interested send me an e mail and i can send you the pictures. I did a post on it when i did it if you do a search on my user name you should find it. When that is done you can eliminate the EGR & the flap in the intake without getting limp mode. (for off road use only of course) Don

Thanks for this writeup Dave! Does the new actuator that you used fit in the stock mounting bracket? So this COULD be done with the turbo on the car if you routed the pressure line around to the test port on the intake (i.e. didn't drill and tap for a pressure port), no?

Yes, it bolts to the stock mounting bracket. And yes, it should be possible on the car, if you can find a way to route a pressure signal to the wastegate. If you do this, let us know how it works!

I'm going to see if I can round up an actuator from an '87. If not, I'll pester you about the part # for the actuator that you ordered and try it out. Thanks again for starting this thread!

You mean the 1987 190D-T, with the OM602.961, right? Let me know what you find out... I was trying to figure out the same thing. All I was able to find online for that model was a Garrett part number of "432340-0004", which is a 0.92-0.99 bar (14psi) pressure wastegate. (I'm not sure about the 4-digit suffix though.) And, I'm not sure if that number is correct, OR if the wastegate from that turbo will work. I'd love to find out though!

That or an 87 300D... wouldn't that work as well? Or is it a different turbo entirely? Thanks!

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?
