I was wondering what the differences are between the 1.9L intake manifolds for Gen 1´s and 2´s. Besides the fact that ty Gen 1 is a bit bulkyier looking by design, and the Gen 2 had a smaller throttle body, doese anyone know if there are and differences in the runner length or diameter, or the volume of the intake plenum. I like the tube look of the Gen 2´s and it looks lighter weight, but since the Gen 2 1.9 seems to be a bit detuned I don´t want to throgh one on and find out that was where some of the power was taken away at. If I get the Gen 2 intak I plan on putting my old throttle body on, or maybe a bigger one. Any suggestions, comments, or Ideas?
