High port vs Low port The 92-93 SE-Rs had a cylinder head with intake ports that entered high in the head and flow straight down into the cylinder with very little bend. The 93 and later SE-Rs have intake ports which enter lower in the head and have to bend more sharply to enter the cylinder, reducing flow at high rpms. These have a more conventional-looking intake manifold with the plenum on top. SCC Dec. 1997
