Right here right now, takai has a little smallport cut and shut manifold for all you RWDers wanting to run a smallport.
Picture is poo, but takai will take more later.
This wasnt done by me, but came on an engine i bought. Comes with a full throttle body, return spring, and TPS. Just bolt on and away you go.
I am very interested. As long as the internals of the plenum haven't been totally butchered I'll take it off your hands. I'll drop you a PM with my contact details.
