need to repair the hose that is broken. This is a large vacuum leak. Look carefully for other vacuum leaks. Next pull off the intake to the turbo. Check for play and ease of spin. If it spins and does not have much play in the shaft its probably ok.
The over-heating maybe a result of several problems. Sorry if this repeats suggestions from others. I didn't read all the past postings. Check or replace the t-stat. When I purchased my 89T it over heated badly. I replace the radiator due to clogging even though it had been fushed regularly.
It sounds like fuel mixture is wrong. You can check the mixture by monitoring the O2 sensor with a digital voltmeter. The voltage from the O2 sensor (the sensor needs to be connected. the disconnected voltage should be ~.5 vdc) should swing between .2 vdc and .9 vdc. High is rich and low is lean.
If the mixture is rich pull the vac. line off the fuel pressure regulator when the engine is running. If fuel comes from the FPR vac. fitting replace the FPR. I would also check the wastegate to see if it's stuck.
I hope this helps and its not to cold where you are. Keep us posted.
