Yeah....the TO4B with the 1.0 A/R exhaust isn't gonna work. I saw that turbo in the classifieds also.......that guy selling it never should have inferred it would work on anything on this board (CA,KA, SR) "this turbo makes serious power"...yeah...on a V6 Grand National.
You could always buy a different A/R for the exhaust side (.63 or .70), but you'd have to know the trim of the wheel. Might as well just goto
www.cheapturbos.com and get one there for a few hundred more.
