Anthony As far as I’m aware the normally aspirated and turbo throttle bodies are identical.
EFI 240/740/940 any difference, don’t think so. Stand corrected though.
IIRC, the only differences between NA and the turbo models TBs is how turbos use a valve husher as a shaft seal for the butterfly; and some of the vacuum fittings are different. A careful study of NA and turbo types will spot 'em.
Initially TBs had different part numbers for LH2.4 and Rex Regina, but then later they didn't.
