| My Z has around 110,000 miles on it, all stock and as you can imagine the engine bay is starting to show it's age. Runs great, but there are a number of things I know if not taken care of this winter will give me a lot of problems down the road. So here is this list I came up with so far that need replaced: Engine: 120K Timing Belt Kit Ramey Z Studs Accessory Belts Clean lifters, replace as needed. Wiring Specialties EFI Harness Various Gaskets Knock Sensor Harness PCV Valves AAC Valve & Regulator Hose Kit Fuel Filter JWT Pop Kit Boost Hoses 300 Degree VG30 EGR Bypass Kit BDE Aluminum Half Moon Exhaust Head Plugs JWT Heavy Duty VTC Springs Fuel Lines Cosmetic Bottom End Gasket Kit Check CAS alignment & pin. Transmission: Heavy Duty Clutch Fork Upgrade Kit SS Clutch lines Transmission Mount OE Shifter Bushings Solid Shifter Mount Goal is to just keep the car running well and reliably for now, maybe next year I can add some go fast goodies. Injectors were replaced with the old style about 2 years ago, hopefully they hold out for another year or so until I can replace them. Turbos spool well, no smoke. I will check shaft play when the engine comes out. Clutch seems good. I'm sure I'll find more that will need replacing once the engine is out. Just wanted to post this and get some suggestions and feedback from the community, please feel free to add or suggest anything you would replace on your Z if it was rounding 110,000. -Tanley
