FJ20ET of the Skyline are 8 injectors? incredible
err, no. thats a mod.
was big back in the day when decent size injectors weren't readily obtainable...
the dr30 manifold runners are slightly longer and the plenum is longer too, although it is reduced in height so is probably around the same volume overall.
all the fuel rails, fitting and throttle body are identical, i think the only other differences are the position of the brake booster line and throttle cable position.
i have also heard that there are 2 different dr30 manifolds, but all of mine turbo or n/a are the same so cant confirm.
