Just wondering if the GSR intake manifold bolt pattern that goes into the block is the same as a b16 intake manifold? Basiclly i chopped a GSR intake manifold cuz im in the process of making ITB's. Hoping the bolt pattern is the same. Anyone know if im gunna have to do some slotting or not?

 

No, The gsr and B16 are different pattern. The b16 and type R are the same, the Gsr and b18a/b are different as well.
