I got this 80 931 with a completely waisted turbo, fans shot, bearings shot, leaking inside and out and just a general mess... But it seemed to run pretty well despite eating all sorts of oil through the intake. I have the turbo off and it's toast, needs a complete replacement, I'm not sure how much of it is savable and am having all sorts of trouble finding good information as to wether or not I can reuse the housings that have been scuffed up by the fans or the fact that the hot one has a crack inside.. That info would be greatly appreciated if someone that knows would chime in but for now this is what I think I'm going to do because I just don have 1k to drop on a turbo that might go on a car that needs tuns more stuff so..
I have an idea to make the car drivable as is for just the cost of a few bolts and maybe gaskets...
To get a good idea of the general condition of the engine and whatnot else to see if it's worth putting all sorts of money into making it right
Gut the fans and shit out of the turbo
Somehow seal the shaft in between the intake and exhaust so it doesn't leak
Block the oil feed and return lines on the filter housing and oil pan to disable the turbo oiling circuit
And reassemble the turbo and the rest to complete the intake and exhaust circuits NA so it will run but with no boost at all, and be slow, probably about 100hp without the turbo because of the low compression ratio and see if it runs decent enough to warrant a thousand dollar turbo..
One concern I have is that by bypassing the turbo oiling circuit it could put more pressure on the other oiling circuits causing the pump to fail...
What do you guys think of this idea?
Stupidest thing you've ever heard right? Ha
And any advice as to how to figure what the best plan is to actually replace the turbo and point me in the right direction would be awesome.. _________________ 80 Turbo - Slightly Modified |
