The Tail shaft is different also.. Will the bell housing and tell housing just bolt on the KA trans? Also what about the harness?biggie wrote:Making sure you know the internals of the S13 SR transmission is the same as the S13 KA transmission. Would just need the S13 KA Bellhousing to swap them to get it to work. Though it should be easier to just find a KA AT. And its very rare that anyone is looking for a SR AT.
