Turbo Supra 1968 Engine/transmission removal

Its really not that hard just do some research and follow the repair manual. If you don't have one get one. And if you have an 86 its actually an 86.5 if it is an MK3. Also if its an 86.5 if shouldn't be turbo unless it was swapped. They didn't start putting the 7M-GTE in until 87

As stated, the engine removal is easy. Only thing I do differently than supraflymkiii is I remove the glovebox, unplug the wire harness from the ecu, and push the plugs through the firewall (with the grommet). This way you can leave the intake intact, and just disconnect the couple of wires that go to the body. Also makes reassembly easier, IMO

Right you are. I purchased this car from a friend who bought it new, and it is in fact a 1987 model.

After I get the unit removed, are there any particular items I need to inspect that my need to be repaired. The turbo in particular.

Since you'll have the engine out of the car you might as well order a gasket and seal kit and replace all seals and gaskets. Check the turbo for shaft play if it has a little its fine but if it has so much that the compressor wheel rubs the housing then its time for a new one, also make sure the inside of the turbo isn't covered in mass amounts of oil. I don't see many other things on these things going bad except for internal parts but I don't thkink yhou'll want to rip into the whole engine.

I know that during the timing belt change, I will need to replace gaskets there. I also will be installing a new water pump and gasket. I located a kit including both on ebay for about 90.00 including shipping. Any thoughts on brand or type?
I suspect that the valve cover gaskets need to be replaced. And for sure I will be replacing the exhaust manifold gaskets. Any suggestion about removing the manifold bolts? I sure would hate to ring one off. I do not suspect and leak in the head gasket. But should I check the bolt torque?

I would go with an Aisin water pump which is what they came with stock, and get a OEM Toyota timing belt there $34 on driftmotion.com. Driftmotion has a ton of nice replacement parts.

Oh yeah for the exhaust manifold stud nuts, they'll either come right off the stud or the whole stud and nut will come out. You should be ok.
