I think I cooked my turbo. - winmutt - 05-24-2011
Parked it over the weekend. Monday morning no power lots of black smoke. I havent pulled the intake yet but.... last weekend I installed a MBC and kept turning it up until the overboost kicked in. Well the overoost never kicked in, probably because I also backed out the alda at the same time. It was whistling but I assumed it was an air leak somewhere. not the singing of the journals burning up.
Anyone know if the engine would still run if the turbo seized? Could it just be rotating slowly enough to not provide boost?
I have been looking for a turbo but now... well its more imperative.

yes it will run but the exhaust side blocks the exhaust (high EGT, no power, smoke).

The one on my car isn't bad
RE: I think I cooked my turbo. - winmutt - 05-24-2011
Oh that is pretty. I was thinking VNT or HY35 etc. Is that one from the rod benders or 3l 603?
RE: I think I cooked my turbo. - winmutt - 05-24-2011
HY35 and HY35W same turbo?
RE: I think I cooked my turbo. - willbhere4u - 05-24-2011
He said in the add it was from an 1986 300sdl after getting it I decided I'm going to save and get a w140 manifold and hy35

(05-24-2011, 05:10 PM)winmutt HY35 and HY35W same turbo?
THAT TURBO IS FAR TO LARGE AND WONT SPOOL WORTH A SHIT
Lol!!!!!!
RE: I think I cooked my turbo. - dieselboy - 05-25-2011
Lol. Putting a hy35 on a friends 85tdt once he gets it.
Yes they only made a hy35w. W= internally wastegated.
An he341 or hy35 are close to the same thing.
They are slow to make boost but it's still drivable and gets better mileage. I need to check my timing as I think it's way out.
I'll let you know what it's like on a car with a untouched pump as soon as we get the turbo.
RE: I think I cooked my turbo. - winmutt - 05-25-2011
(05-25-2011, 01:38 AM)dieselboy They are slow to make boostThis is not what I want. However you stated you get 10psi at 2500. What about at 2000? This us going on a 603 so it should spool better than the 617.
RE: I think I cooked my turbo. - dieselboy - 05-25-2011
Oh a 603..... Ive yet to work with one of those. It's a cheap turbo that has been proven tough and reliable. 360° thrust bearing, fat shaft, etc.... Couldn't hurt to try it IMO.
RE: I think I cooked my turbo. - winmutt - 05-25-2011
Its hard to find a good turbo suited for the 603. Either all to small or too larger or unobtanium.
Dieselboy, what kinds of psi are you seeing at 200rpm?
RE: I think I cooked my turbo. - willbhere4u - 05-25-2011
At 200 rpm I bet none!
RE: I think I cooked my turbo. - dieselboy - 05-25-2011
I'd need to drive it and report back. I don't remember. I want to say 5 but I've just been driving the thing lately. My car is never at 2k really. 3 is the sweet spot.
RE: I think I cooked my turbo. - winmutt - 05-26-2011
Im looking for a hy30 me thinks. Hard to find tho.
RE: I think I cooked my turbo. - dieselboy - 05-26-2011
Any other mods done to the car?
RE: I think I cooked my turbo. - winmutt - 05-26-2011
Not to the engine yet. I have a euro manifold I will be using obviously. I want to get a modified pump but with a kid due in July I have other priorities. Also needs a new hg maybe new head so other priorities are first.
RE: I think I cooked my turbo. - willbhere4u - 05-26-2011
what's an hg?

It's ok, took me a second as well haha
RE: I think I cooked my turbo. - willbhere4u - 05-27-2011
What we really need is a ball bearing turbo comparable to a Holset hy35

Right!?! That would make for some super spool!
RE: I think I cooked my turbo. - winmutt - 05-27-2011
They are ridiculously expensive.
RE: I think I cooked my turbo. - dieselboy - 05-28-2011
What's that?
RE: I think I cooked my turbo. - winmutt - 05-31-2011
Ball bearing anything... So I have looked and looked and it seems the HE341 is the easiest to find replacement upgrade for stock/semi stock 603. I cannot find a HY30W to save my life. Given Lances report ont he HE341VE I am hoping the HE341 is a easy drop in as well.
ps I asked Lance to sell me his turbo and he said he was disappointed in me and had lost faith a long time ago. Talk about pot kettle hello black.
RE: I think I cooked my turbo. - willbhere4u - 05-31-2011
The pot calling the kettle African aluminum!

HE341 is on its way. Measurements are 54/58/9. Still not sure about the 9cm housing but we shall see!

Nice. Where did you end up getting it?
The Garrett turbos originally on our cars is old technology

Well yeah! they're like 30 yrs old!
RE: I think I cooked my turbo. - winmutt - 06-03-2011
I dont think the wheel geometry has changed on theses older garetts since wwii.
I got it off 4btswaps. If you have time its a good chance you could pick up a hx30 or hy30 from there.
Anyone know what size pipe is used for the exhaust on the 603?
RE: I think I cooked my turbo. - dieselboy - 06-03-2011
60mm would be my guess.
RE: I think I cooked my turbo. - winmutt - 06-10-2011
HE341 is a big turbo. I think the specs I have are incorrect and that its a hair off the HE351 on the comprssor wheel. As there is too much axial play and a guy just replied back about a HY30W I am going to try to return this.
RE: I think I cooked my turbo. - dieselboy - 06-10-2011
Hy30? Thats tiny. To be honest I've never seen one.
RE: I think I cooked my turbo. - winmutt - 06-13-2011
(06-10-2011, 12:13 PM)dieselboy Hy30? Thats tiny. To be honest I've never seen one.
Its larger than stock. Should be a good fit for a DD. 3" in and out t3 flange. No weird routing issues (since I am not using IC yet).
RE: I think I cooked my turbo. - winmutt - 08-12-2011
Soooo... Got the left side of the engine off, turbo manifold etc last night. 2 of the studs are snapped
....Once upon a time I took off the wastegate arm and lost the circlip. So I didnt cook the turbo, arm was just hanging off.............
For now I will probably mount the euro manifold and put the stock turbo on for another week or two until I can finalize fitment.
RE: I think I cooked my turbo. - dieselboy - 08-12-2011
Been there done that lol.
