you dont need a plate, the bolt pattern for the TB on B D H C and F series intake manifolds are the same. the bore size is diffrent, and unless you port the manifold or get an aftermarket one you will have a lip on the intake.1990crx said:i thought that on a b motor that the mounts were diffent spacing then the d motor. so if thats the case your telling me that i can get a tb from a gsr and it will bolt up. i dont think so. i will need a plate but i dont know of any one that makes one or where i can get the spec. on one of them.
