There was a JDM Fairlady Z of two liters.
I think it used a smaller displacement version of the six, but I'm not sure.
The 2L Fairlady (Datsun 2000 Roadster) OHC U20 engine was a very different engine from the 1600 Roadster pushrod, the OHC 1600 510 and the OHC 240 Z 6-cyl engines. It still had a vestigial in-block camshaft (called a jackshaft) that powered the fuel pump, oil pump and distributor. It was an interference engine (ask me how I know!) that was a screamer, especially in the twin Mikuni Solex carb version, but had reliability issues (mostly timing chain related). I had 3 of them back in the day, and they would pass everything on the freeway except a repair garage.
