Found some videos filmed with phone right after tuning the ITB's and ECU. No go but sounds lovely..

 

what makes that a mazdaspeed?


looks like a mazdaslow.

 

Yeah, it wasnt the fastest on the road, tho kept 190hp turbos behind on track.
It was made or tuned by Mazdaspeed at Japan 1996. offical name was mazdaspeed B-spec stage I, It has same cams as M2 1001 (1001 has mazdaspeed's cam's), full exhaust from mazdaspeed made by maxim works, Kaaz lsd, original free flowing panel filter and nice plate from mazdaspeed.

Similar than this but no SC in mine..
