I'm in the process of converting a stock and caravan intake manifold to MPI and wanted to know what your thoughts on injector placement.  I believe the best place would be on top spraying towards the intake valve.  What about placing them on the bottom and spraying upward?  I've seen some conversions done at the bottom.   Go here for pics with injectors at the bottom (Lower Shores Performance Prototype manifold and old CNM MPI): http://www.starquestclub.com/index.pl?boar...;num=1095039863

Looking at buying a mpi car with the sds em-4d was hoping some guys here were running it and can give me there opinions about the system and any pros or cons I might consider before purchasing thanks Sean
