hey guys just wanted know if '99 twins have the same exhaust manifold???

are they interchangable???

thanx in advance
mike

 

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).

so yes or no lol??

thanx for the help fellas

 

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.
