this should be a good one-
i have just aquired my old sapphire as it has been crashed so i bought it back for the engine to put into my rs500.

it is a big spec engine,but im wondering which set up is best.i have a p8 ecu which is mapped for the engine,although not for a t4 which it will now have,also have a wrc siamese 8 injector manifold with 8 greens,and a loom to run it.it all ran very well in my sapphire.over 400 bhp

would it be better to keep the rs500 inlet manifold,which i think i would prefer as the car is an rs500 and use a different ecu etc,or will the ecu be ok to run the rs500 set up with a different chip?my original plan was to use l8.or is the other manifold superior?

has anyone tried both set ups?
help!!!!!
