I got a 65 mm throttle body from a 5 series BMW car  (at a u-pull-it
junkyard)for real cheap- about $13. I wonder if it might bit a bit
on the small side- it works out to be around 2 5/8" i.d. Any
opinions about the size of this thing? Brian Trubee

Might be OK Brian. Try it and use a water manometer to measure
the pressure drop at WOT.

Brian,
I'm not sure if this is apples to apples, but the Mustang guys routinely use the 65MM
TB on engines up to 350 HP.  My '89 5.0 Mustang was rated at 225 HP and used a
58MM MAF and a 60 MM TB.
