im about to rebuild the bottom end on my xu5 project. nothing too serious. im thinking i will just inspect components for wear and only replace the rings if i can get away with it. does this sound resonable. i will replace brgs if needed? the crank and flywheel will be getting re-balanced as they are not a matched pair was also hoping to do this with the clutch attached?
im after any advice, as i have only ever rebuilt grey and red motors mostly, with the odd L series datsun also. what should i be looking out for on the xu engine? what components are essential to be replaced and what can be re-used if in good condition.
i was thinking of putting in some mi16 liners while its apart as i have heard they have a thicker wall section and will make the engine more reliable/stronger? will mi liners fit the xu5 block without any issues and is it worth the effort if i can get hold of them easily.
plans are to put a rebuilt head on top of all this with a clean up in the ports new guides and 3 angle valve seats. it already has .040 off the face of the head and may need more, im aiming for about 10.5: CR. will be using a 280 degree cam with about .470 lift. eventually with twin 40mm carbs and a recurved dizzy.
