i dont know if this is relevant at all.. but i only get just over 100-120ks out of approx 20L of PULP from my 2 litre 18R-GEU.. It is running the 22RE afm and quite similar EFI setup and is still a bit rich low down in revs, but is this just the kind of economy to expect from a thirsty late 70's 'revvy' motor on standard EFI?
