Ok I am nearing the end of my build and I have these 2 tb's, one is said to be ITR opening is 62mm and tapering to a 58mm end, it also does not have a IACV just an inlet and outlet and only has one sensor spot (TPS) and the butterfly is stamped 1DA. The other is a ? not sure what it is but it starts at 62mm and finishes as 60mm and the butterfly is stamped 604. It also looks like it has been bored/polished right before the butterfly to the end very nicely. Both line up and bolt onto my ITR intake manifold, but what exactly do I have here???


Pics of the two and some measurements if you can read them.

58mm at the plate/end early b16a's (obdo etc) or other non B16 motors like Fs maybe
60mm at the plate/end b16a obd1-2 / CTR's
ITR is 62mm at the plate and i think larger at the opening around 64.5/65mm

Well I was looking for someone to confirm your data, thanks for reminding me why I usually don't come to HT for anything other than the regional FS thread.
