we recommned the ID 1000's. you would want the standard 14mm x48mm injectors that the 2006-2011 SI uses. we have seals to make the injectors compatible with the bored out injector pockets we did for you in the RBC manifold.
As far as the RBC manifold, we have the piping kits compatible for it, won't be a problem at all for any RBC users out there
