Estyre stick to reading my PMs & answering them as you have of now & sort it out.

Sc14 is the closest to A14/a15 unlike the Amr500 which Ive chosen to use for space issues and a certain layout. I would have used an sc14 or IHI AX1200 from a Mazda eunos which can flow as much as 420hp at 17.5psi in the right engine due to higher rpm limit than sc14 but space is limited in a 1000 and only after 100 lbs of torque atw.
