Ha, Dave and I were on the same wave-length...spooky

LOL! Yup, looks that way!

But I think what I've done seems pretty secure.

An update: I ordered the tubing that ATP recommends but it's too loose on the actuator. And they claim that the 1/8" hose is too tight on the pressure fitting. So it looks like the fuel line I'm using is the best thing I've found. But I've got to think that somewhere out there there's a hose that will fit over the pressure port yet is squishy enough to tighten on the actuator.

I've got fuel line on mine..with hose clamps.

I had thought about getting some hose from McMasterCarr

McMaster-Carr

not sure on what size you need though.

Are you using the same pressure port that I'm using?

Of course this problem would go away if we just used the line from the ALDA.

I like the idea of running the line from the IM. I think my set-up is fine....I just want to make sure pressure leaks won't develop over time.

Im using the one next to that pressure sensor gizmo on the intake manifold.

You sent me a picture of it a few days ago. I dont recall if I replied (sorry!). i think you were asking about that pressure sensor. I believe that feeds pressure data to the EDS computer so that it can control the wastegate..I THINK

According to some others I asked, it controls boost signal to ALDA. If it controlled wastegate, that function would be eliminated by the mod.

But what fitting are you using? This one? Fitting, Pressure Port, 90 degree, 1/8" NPT to 7/32" Barb Fitting : atpturbo.com

joegolden · #**488** 01-20-2014, 06:23 PM

I wanted to post here that I have a new ATP actuator for sale. I have the little fitting as well

Fitting, Pressure Port, 90 degree, 1/8" NPT to 7/32" Barb Fitting : atpturbo.com

Also included is a decent length of hose that is linking the 2 together. It seems like it was a real tight fit on the barb fitting. But its fit!

Anyway I bought it to do the swap on my 91 300d but after removing the ALDA and replacing all my brittle leaking fuel return lines my car would fly! I had no actuator problems after all. Anyway the car is sold and longggg gone so I have these new parts just sitting around. Not sure if someone wanted them for say $70 including shipping. Lemme know if there is any interest. Thanks Joe

yes I am interested...if you like email or PM me
thanks
Chris

Used the first nice day in New England to do the swap on the 92, the one my son drives. It had been noticeably sluggish. Why? Don't know and don't care. Did the swap, it is quick once again.

Made a nice tool discovery along the way. Most of you guys probably already know this, but I never knew there was such a thing as a flex socket extension. Made all the difference in getting at the upper wastegate nut.

I feel like placing a recent posting to an epic thread is doing a disservice

... but I had a quick question. APT is out of stock for the actuator and I only saw briefly a mention on page 21ish of an eBay actuator. I didn't quite see how that testing went. Were there any other sources for 433489-12 than APT? I'm starting the google finder of all things for that part number now.

I've bought a barely running 92 300D 2.5 and while going though the repair list, and having the intake/ect apart for cleaning, I might as well do the EGR delete.

So, I'm very sad if I can't get the actuator.

Thank you for contacting us. Currently Garrett part #433489-12 is out of stock. We are trying to order additional units.

ATP-FTG-040 is in stock. Feel free to order online at ATP TURBO - The Premiere Provider of Turbocharging Components

I've been running that eBay actuator since I installed it. Coupled with a cheap manual boost controller it has been working perfectly fine. No issues that I am aware of.

shertex · #**493** 07-30-2014, 12:40 PM

When I was looking for mine, ATP was the only source I could find. At that time as well they were out of stock....but not for long. So you might not have to wait too long.

Perfect that you didn't have to wait too long shertex.
I've got a long list of repairs to make so I can hold on this one for a bit.

At least worst case I can go with James Dean's setup with the controller.

I have a 91 without and 92 with the actuator mod... if the factory setup is working I would not hesitate to stay with it until it doesnt... the reason I say this is that the factory setup keeps the wastegate open for more of the running time then the manual actuator that is part of the mod... resulting in cooler average manifold temps and less spool up time on the turbo... that said I have not put a pyrometer on eather but I just put the head etc back on the 92 after major overheat of the engine and I was tweaking the full shut position on the mod actuator and was giving some serious thought to the reality of having the wastegate spring loaded shut at all times excepting those briefe periods when due to acceleration the manifold exceeds 14 psi...that said there is nothing inherently wrong with setting up the mod many big diesels are set up this way but the practical difference is that with the 602 engine we are dealing with aluminum heads that tend to be the weak link in the engine... hope this is some help ... just my experience and observation... best

by the by... as far as I know you can do the egr delete ... just blank off the port but leave the flapper and all vacuum lines connected and as far as I know the factory setup will work as the system does a brief close on the flapper after starting creating a artificial manifold vacuum condition ( which never exists in a diesel ) and as long as the computer sees this the wastegate system should function fine.
