Turbo Supra 1968 Engine/transmission removal

professorbob · 05-17-2010, 05:54 PM

Day 2 was about five days ago, so I will try an remember my observations with several questions to follow.

We lifted the car and I removed the dirt pans and various hoses to the cooler and radiator. .
The hoses were pretty strait forward for removal from the top. The electrical disconnects were very difficult to operate, ass the has such small latches. Can see how it would make the install easier, but hard to manage with such tight short wire connections.

The under engine is quite clean considering the 1987 age and 116,000 miles. No leaks except from the Power Steering reservoir hose. I will probably have a new one constructed, unless I can locate a cheep replacement part.

Broken parts thus far.... So easy with old plastic stuff. Radiator upper ear. I will need to epoxy it back on. The windshield washer plastic hose connections. Looking for a replacement.
While trying to get the air cleaner plenum off it cracked at the turbo charger intake.
Anyone know where I can get a replacement, preferably OEM Old New Stock for a reasonable price?

I have the fan and shroud, the radiator, the water pump fan, the alternator, and the belts removed.
Trying to determine what hose under the intake will need to come off.

I removed the Power steering hoses and let it drain.

I also need to know about the the Transmission cooling lines. Can I disconnect them from the transmission and leave in the vehicle, or are they attached to the engine.

Any suggestions of how to get the three down pipe nuts off the exhaust port on the turbocharger. The have really rusted. I have been soaking them in oil, hoping to be able to get them off. Are these studs in the exhaust flange, or are they bolts dropping through holes in the flange.

Torque Converter, any source for a replacement converter at a fair price.
When the transmission fails, it it customary to replace the converter as part of the rebuilding process?

What should I be looking for in my transmission builder for this A340E unit?

On the engine pull, what about the pipes and tubes below the intake manifold. Can they be left in place an just take out the bottom bolts in each engine mount and lift it out as a unit?

More questions later. Thanks

Are you talking about the accordion hose which is rubber and connects to the turbo or the hard plastic which holds the air filter and bolts to the afm? If you're talking about the accordion hose you can get one brand new on driftmotion.com for a pretty fair price otherwise watch the FS threads for a good shape one.

The tranny cooler lines are bolted to the engine in 3 different places iirc. If you're pulling the engine too I would just leave them attached and disconnect them at the tranny and pull the whole engine and tranny as one with the lines still attached just be careful that you don't bend them.

As for the exhaust nuts, they are studs with nuts on them. I doubt they'll break off, if anything you might just pull the whole stud out of the elbow. If they do break then you get to have a ton of fun with a drill and get some cobalt drill bits and drill them out big enough so you can retap them stock size if you can.

You should be able to reuse the torque convertor they usually don't go bad that often.

To get the engine out you will have to atleast take off the upper intake plenum. so you can just leave all those metal lines under there just make sure you get the fuel lines disconnected and all the connectors under there. The starter wires are usually kind of a bitch but with some patience and good hands you can get it.
