Hi all..

After a few years happy(ish) motoring, i'm back on the board and looking for help.
I have an 81 RoW turbo in good condition that was cared for, and apart from the annual four-figure repair job was serving me well. That is, until I broke the turbo.

Referring to this very helpful image provided by ideola in an earlier thread:

I have broken part F completely in half, separating the shaft from the turbine. As the turbine was disconnected it has made some slight grooves in the inside curve of part G. Interestingly enough, it doesn't fit through the opening, so just rattled around in the cavity. Apart from those two parts there didn't appear to be any damage, and neither the mechanic or the turbo people who inspected it pointed out any other damage.

So, the story so far is that I had a turbo place look at the turbo and they told me that:
- the parts I need are not available
- these turbos are no longer made by kkk
- the last turbo in stock at kkk was available for a price of AU$5500 landed

Also, my mechanic spoke to them and determined that the odd angles of the pipes combined with the cramped space would mean that converting another turbo model to the car would not be possible / financially feasible.

Considering that I bought the car for AU$9300 and probably wouldn't get much more for it now (despite spending probably half that on it) I didn't think it was worth it. The car was in beautiful shape when it died, dyno'ing at 167.3 BHP at the rear wheels - stock configuration.
I believe the rest of the turbo assembly is in good order.

So, my questions:
- if I buy a used turbo can these turbos be renewed with new seals etc?
- if I buy a used turbo can they play "best-of" and make a good one from the two?
- how much should I pay for one?

My mechanic wasn't able to find a used turbo for sale, but I think that i'll try you guys here and also try ringing around every turbo place in Australia to see if I can find something.

The other part of the story is that I work full time and am beginning uni (night school) next year and am now in need of a reliable car, which the porsche hasn't been (it seems to need about a week or two off each year holidaying at the mechanics). I'm also changing my financial priorities and so keeping this car going has been bumped from the list. (I know.. i'm bummed about it.. my g/f will be more bummed, we were talking in it when she decided she wanted to be more than friends, so she's going to miss it as well)
Anyway, so i'm now considering if it's going to cost more to fix it than i'll re-coup from selling it as a running car instead of for parts..

HELP!!

By the way, I am in Perth, which is the most isolated city on earth (I believe) so there isn't a roaring trade of porsche things going on here..

Advice?

Edit: spelling.

I might be able to help you out depending on exactly what you need. I am in the early stages of putting together a hybrid K27/K26 turbo, and I have a couple of K26's disassembled, plus a few extra bits floating around. There is a good chance that I will have the spare bits you need. Unfortunately, I'm not working from home today, so I can't run out to the garage and check my stockpile compared to your post right at the moment, but I will look into later this afternoon.

In the meantime, the most important thing we will need are the part numbers off of your compressor housing, as well as the model year of your car (so we can determine what series unit you have). Also, I don't know if there was a difference in the Rest-of-World units from the N.Am. units, but I figure other folks here can chime in and help us sort it out. Please post all of the numbers on the KKK tag that is on your compressor housing. Also, you can PM me if you want.

P.S. Forgot to mention, it should be very doable to rebuild the unit. Prices here seem to run between $300-$600 depending on damage and parts required. If you can't find a reasonable rebuilder near Perth, we might be able to make arrangements with Michigan Turbo in Grand Rapids, who is the supplier I've been using. There are other rebuilders here in the states, but if you end up needing my parts AND a rebuilder, I'd be willing to ferry stuff over to Grand Rapids since I have to make a trip there for my hybrid unit anyway.

Hi ideola!

Thanks for the info and possible assistance..
I am getting the part numbers of it for you (it's at the mechanics and I forgot to write them down when I had it - silly me!) but it's a 1981 model, so I believe it's the series 2 turbo unit.

If you have the right parts i'll go visit the turbo place I talked to here and see if they think it's possible and what parts they'll need. That way we can minimise on what gets shipped etc, and leave you with the most parts should you need them.

Thanks again for your help..

OK, sounds good...make sure you also get the part number off of the back of the compressor wheel. You may have to clean it quite a bit for the numbers to be visible. It start something like 5326...

apparently it was reconditioned at some point, so the mechanic isn't sure what numbers will be what, but here they are:

KKK Model K26

Reconditioned by Dynamics
Serial no. WHR 9909A
Part no. 5326 370 6020 M
Official Porsche P/N 931 123 004 07

Recently smoked my motor at a track day and was offered a second hand turbo if I needed it. As my problem was a holed piston (see thread in 931tech) have not taken up the turbo offer. PM me if you want the contact here in Melbourne.

I have spoken with my mechanic who said that I would need more parts than I originally thought.

I sent him the diagram (very useful, that) and he said that I would need D,E,F and G as they are all damaged, and also, as I am replacing the shaft, I would also need a number of the clips and rings etc.. apparently the shaft and these pieces will tend to wear together so not all parts will fit together well if they are worn different amounts or differently.

I haven't seen the turbo myself since finding this diagram, but I will be having a look at it next week.

All the more reason why a whole unit closer to home would be better if it is available..

Kye, definitely, if there's a local unit, use it...much better to have spare bits in your stock pile

I was also going to mention that while I have an extra shaft with hotside turbine wheel, I do NOT have an extra turbine housing; I have two, but one of them is cracked...might be repairable, but it wouldn't be cheap...better to find a good unit locally.

In any event, don't hesitate to look me up if you hit a wall...

For that price I might glue it on with some piping coming out and pretend my NA is a turbo

hi all..

my lead in Melbourne didn't pan out, as the guy had a brand new aftermarket turbo he was looking to fit to a 924NA, and not a kkk one from a 924T.
I have been in contact with a turbo expert who is familiar with the 924 turbo and has been working with them since new, and is very familiar with the crank case ventillation issues and the other peculiarities of the cars. He works with one of the turbo places here - Turbotech.
I've organised for him to inspect the turbo and car with the aim of identifying a possible aftermarket turbo that might be suitable and what adapters/modifications would needed to make it fit.

I will let you know what he finds.
