Posted: Fri Oct 09, 2015 3:09 am Post subject: 1980 Turbo removal |
|
|
I have followed the Haynes manual procedure for turbo removal and the task has been moving forward as expected.
Now, I have all of the nuts and bolts removed from the turbo. It's loose, but I can't get it off of the exhaust manifold studs.
The manual says to unbolt the turbo mounting bracket, but I'm not sure why. I have the two, (of the 3?) bolts out of the bracket and I can get a wrench on the third, but it slips off when I apply pressure. Plus, when, if, I do get it out I wonder if I'll ever be able to get it back in.
I've been dabbling with this for 2-3 months now and really want to complete the job before the Wi. winter sets in.

The answer lies within the question, grasshopper. _________________ Toofah King Bad

Advice? |
First off you have to get the whole exhaust out of the way, and pull the exhaust manifold-turbo bolts..
There are 2 allen cap like nuts that attach the turbo to the block mount where the oil feed comes in, remove the oil feed and those 2 Allen cap nuts.
Then there are 4 bolts that mount the block mount to the block, pulling the turbo off of the block and the exhaust manifold should be the last thing you do, get all the bolts out/loose that you can for wiggle room, those block mount to block bolts can be hard to get at..
First you need to make sure you have EVERYTHING else off the turbo including the oil lines and all plumbing, get it as loose as you can.
You may be able to remove the turbo from the block mount and get it out the front, you should at least be able to get it pretty loose off the block mount in order to gain access to the block mount to block bolts.
With the big original compressor housing you may have to move the sway bar and steering rack to get the turbo out the front, my first time I completely removed the say bar and took the right front tie rod off the spindle, and unbolted the rack to move it out of the way..
Advice? Be patient, it is possible, but pretty much the hardest job to do on a 931, if you can accomplish this then you can accomplish anything on the car.. _________________ 80 Turbo - Slightly Modified |

OK,
I'm at that last step. Exhaust, wastegate, air intake, fuel, tie rod, steering gear, starter, etc. are all out.
Yes, the 4 (?) Mounting bolts are hard to get to. Getting them back in will be a joy also. But, I guess I forge ahead and find a way to get them out.
Thanks for the support. _________________ Jim Baldwin

I've removed and installed an early turbo multiple times without the need for removing the engine, sway bar or crossmember. A nice thing about the turbo in this car is that the turbine end can be loosened and rotated. This makes it much easier to remove it from a mounted motor. This also helps when remounting it in the car, as it helps all mounting surfaces to match up such as the oil line/mounting bracket and exhaust manifold.
Of note, I've had no issues with a loss of boost or such issues afterwards. Then again, this is a relatively fresh rebuilt turbo being used. Properly re-torquing the bolts is still possible once in the car. _________________ 1977 Porsche 924 - sold
