Yeah Dennis
I'm looking at Autronic SMC or Vipec now.
Would aiming for 400hp create a problem with lag?
Had a rally Mazda years ago and built it with small periphial ports rather than go for the big ones of the all out power monsters.
Section of the rally up the side of the Darling scarp (Zig Zag) beat all the other Hi po Mazdas and the works Stanzas (Dunkerton,Fury) and Works Fords (Carr, Bond)
One rare claim to fame for a poor privateer but taught me to chase low down power too
