I have researched previous posts, and I was unable to find a definitive answer to my situation: I have a 6 speed transmission from an RSX Type S on the way. I was wondering if anyone here has swapped one onto their K20A3? If so, are there any modifications that need to be made besides the shifter mod? Will the tranny bolt in to the Si subframe with the Si brackets, or are RSX brackets needed? I have heard that the Si axles will work with the new tranny, but is the intermediate shaft from the RSX needed? Any assistance is greatly appreciated.
