It may be new in the Tacoma but Camry, Avalon, Highlander, GS/RX/LS350, etc. have been using variants of the 2GR since 2005 and the very same 2GR-FKS since 2015. Also the selection of a car engine for Toyota in a pickup is not new, the VZ series V6 was first used in the Camry and the R series were used concurrent in Celicas.I would probably put Toyota last on this part because of the new unproven engine with quite a few complaints.
That's something forgotten, that the early 1GR-FE 4.0L engines had head gasket issues not unlike the 3VZ-FE 3.0L years earlier that everyone loves to hate.I had the first year of the 4.0 in the 4Runner and it let me done. After that they seemed to get it squared away.
