almost positive they are the same just with an "abraidable" (spelling) seal around the blades that allows them to flow better. seems that the rx7store sells them as a driect bolt on upgrade.

I dont think he was talking about the turbo's I think he meant the manifold that goes from the engine block to the turbos.

I havent seen first hand but I believe the Series 6(92-95) manifold was unchanged in the Series 7(96-98) and 8's(99-02).

i was just saying that the footprints where they mate up is probably the same... i never thought about the flow characteristics... sorry, that's as much info as i can offer without possibly misleading you.
