i already have the rs500 manifold as my car is an rs500.what im trying to work out is the best system to use on this engine im fitting.the engine came with a siamese 8 injector manifold with loom and p8.should i just use all that as i have it already if its or would 4 greys suffice on the rs500 manifold,especially if its going to cost 750 to be able to use the other 4 injectors.
im tempted to use the wrc manifold with this engine as i used to own the car and know it works well.just get it remapped to suit the t4.
on the other hand it seems a shame not to utilise the rs500 manifold as it would look right under the bonnet or should i just say fook that and go with the other stuff
