If you must, the following will be required
Removal of timing belt, so follow a 60k service guide via courtousy Z
Remove lower crank sprocket sometimes needs to be cut off and replaced! remove oil seal
jack up vehicle and place on axle stands with plenty of clearence, idealy a 2 post ramp is beneficial.
Engine supported via hoist or similar
Disconnect turbo return feeds, disconnect oil cooler hose and plug, drop crossmember to get pan out from underneath.
Access to oil sieve return is now accessable unbolt and remove from block. undo 5x10mm bolts to front of oil pump and gently pry away and off crank. Pay special attention to not damage the crank or mating surface.
Replace pump with gasket sealent, new crank oil seal. torque evenly
Refit oil return pipe to block. New sealent required between seal of pipe.
Refit sump, plus gaskets at both ends. Make sure the mating surface has had all the old sealent scraped and cleaned away, apply a neat bead of sealent around the sump, have someone place the sump in position with you as its a fiddle on your own underneath the vehicle.Do up bolts on opposite fashion to being sump in evenly, work in a criss cross style.
Refit turbo, oil cooler hoses.New filter
Evenly tighten crossmember.
Remove hoist or form off engine support
Refit new timing belt and NEW tensioner follow reverse fitting of a 60k service guide.
refil with new oil, make sure you have checked everything including oil level.
Start car and let idle until up to temp. turn off and recheck oil level.
Check oil pressure, but dont go by the stock z sender as its pants. If your worried about pressure get an aftermarket one installed and taped in to the line somewhere, namely the pants oem position. defi or greddy are well made and relible.
Iv not worked on a Z for a while so i may of missed something, but everything above is required
