18Z parts availability and fitment
Posted: 24 Apr 2023 12:32
I'm new to Datsuns, so I'm not sure what will fit what and what's good to use.
I have a 620 pickup with a L20B and a U67 that I don't fully trust ( head gasket ) and want to go through it. I found a deal on a running 18Z cross flow engine and what I assume to be a 4 speed, that's been stored a long time. I'd like to have a spare engine I can test run or freshen up with new bearings and rings to run it in my 620 while I rebuild my L20B. I heard that the crossflow Z engine isn't liked due to compression or flow issues. I'm not so concerned about that, compared to parts availability and fitment. I'd like to know if it'll bolt up to what I assume ( low 5th gear ratio ) is my non dogleg 5 speed. If not, I'd be OK using the 18Z 4 speed, as long as my driveshaft will fit without mods. My 620 is a king cab.
At the minimum I'd need a 18Z carb rebuild kit, if the engine runs OK on the bench. If not, I'd need bearings, rings and gaskets. I assume the 18Z wasn't used in the US, but was imported as a "low mileage" engine from Japan or overseas.
