I was wondering if i could call on some collective wisdom, i need a new turbo cartridge for my old p38 dse 2001, dont ask what happened, of course its a td04 11g-4 but my question is will any td04 11g-4 cartridge work? And what is the significance of the other numbers?
Dse's are pretty uncommon here so parts are hard to get. I still have the old turbo so i just wanted to chuck a new cartridge in the turbo housing. Can anyone clarify for me so i can stick the old girl back together

From what i found out look at replacing mine was that the CHRA which is what they call the middle bit is the same for quite a few motors, they even do one on Alliexpress.

Someone did this recently. Might have been @Slooby ?
 
I didn't buy a new CHRA for mine, but did rebuild it with an after market seal and bearing kit (which was about £25 here in the UK) because the shaft, exhaust compressor and exhaust wheels were fine...right up until I tried to torque the new left hand thread 12 point lock nut down at 8Nm and discovered that my 1/4 drive Teng torque wrench didn't actualy have a torque function when switched to left handed tightening :mad:

I ended up buying a Mellet branded new shaft complete with exhaust wheel which was about £40 and was a lot more careful about tightening the lock nut...

As the Mitsubishi TD series turbos are sleeve bearing types they are pretty robust and basic so a DIY rebuild of the CHRA is perfectly acheivable, asuming your exhaust wheel, shaft and compressor wheel are undamaged or aren't worn.

I'll dig into my project thread to find my turbo rebuild sections as I photographed everything, and also detailed which version of bearing was used by BMW when they manufactured the turbo under licence from Mitsubishi.
 
New (Melett) exhaust wheel and shaft turned up last week and I set about the second, partial, rebuild (partial because I only needed to refit the shaft and wheels).

First off here's a line up all the CHRA parts from the first full rebuild:

And now the assembled CHRA with new shaft and exhaust wheel:

The turbo is now all back together:

Had a fair old battle with getting the compressor housing circlip back on as I didn't have a big enough set of circlip pliers, also the all-metal lock nut on the exhaust housing to CHRA V band for some reason seized and snaped about 3mm off the end of the bolt, and the exhaust housing to CHRA joint didn't go back together as tightly as I expected. After a few attempts to get it close up I measured things up with my vernier and it would appear there was no way it could close up tight anyway, so fingers crossed it's all ok.

thanks guy but the shaft is broken so no rebuild for me although i have a rebuild kit

Was the compressor wheel damaged, or can you, just like I did, get away with buying a new exhaust wheel and shaft for a lot less than a complete CHRA?
