i cleaned all the connectors today. maf. cas. tcs. i cleaned throttle bodies. put 100 octane in.new fuel filter and it runs great now. i also taped off my air intake the top of it where it looks like a endo cone.that helped as well. the last things i have to do are coolant temperature sensor connector. run seafoam through the gas and oil and air intake, i have a driveshaft i will be putttin in hopefully that will help.if anyone has any other suggestions for cheap ways to make a z faster let me know

 

do you need that connector for the sensor?

 

I hope you're kidding. Try searching. This question is Z32 performance 101. There are literally thousnds of threads where this has been dsicussed. Not sure what your definition of cheap is, but nothing on this car is 'cheap'. Also, it's hard to recommend anything when we know nothing about your car.
