There have been many discussions of both temperature and tachometer systems in these boards. The current tachometer discussion is here. You can search for a temperature discussion. You will probably need an automotive type temperature sender though rather than the types normally discussed on the board.

Some questions: What kind of LED display are you considering? 7-segment? How about a bar graph display showing 1000 to 10,000 RPM in steps of 1000? Why do you need a tach? Isn't the exhaust feedback enough?

For temperature, consider the LM135/LM235/LM335 which output 10 mV per degree kelvin. All you need is a bias to convert to degrees C and a voltmeter for readout. Or, you could use the LM34 which outputs 10 mV per degree F.
