basically replace the cat converters as they are blocking the exhaust system and preventing your over 45mph problem
replace the TR sensor/ switch as you have not mentioned a transmission problem
Rectify the problem with the KS as it controls the air/fuel mixture setting which contributes to the car getting hot.
check vac tubes for leaks by slightly bending them to check for cracking Also check PCV valve this could be jammed open, wash in petrol to clean or just replace
Did you hook all the lines for the fuel pump up when the engine was re-installed? It is definitely a fuel issue. Disconnect the fuel line and crank over the engine to check for fuel supply.
I think you should buy repair manual first for your vehicle after that it will be easy for you to solve the problem. Check the link may be you will get something useful here 1988 Nissan 200SX
it sounds like your transmission is slipping. they make this chemical you can get at a part store, its a transmission stabalizer. it should help with the grinding noise and transitions to the other gears. also give your truck a complete tune up (oil change, fuel and air filters, spark plugs etc.) it should help with the fuel consumptions.
Is the choke opening up all the way after it warms completly up ? and have you checked the fuel lines to the gas tank they might have got pinched in wreck.
