I have a 3SGE that is in a gen1 celica, and I have been thinking about replacing the intake manifold, now I am wondering how complex do you have to be with this sort of thing, I am thinking about adding a supercharger at a later date for some added fun, just wanted to get rid of the stock intake manifold and maybe add the supercharger at the same stage. Just wondering about all the complex maths that goes into their design and how hard it would to be to rig-up/ have someone rig up a simple setup.

My 3SGE currently uses a TPS which could be repositioned quite easily, but from there I am at a loss.
