Engine of the Day: Nissan VH

Developed by Nissan for use in the President limousine and the Infiniti Q45 (not to mention the R390 GT1 race car), the VH series of V8 engines was manufactured from 1989 through 2002. Available in 4.5 and 4.1 liter displacements, the aluminum-block VH sported a DOHC valvetrain (with variable valve timing on some engines) and- once the whole timing-chain-guide thing got sorted out- smooth power and decent reliability.
