I think they only made those for a few years. Maybe 89 to 93.

Fred,
The 20B housings seem to have a code stamped in them. The higher the
number the later the year. Mine are marked C927, with a black paint
surrounding the number. However, I know of no cross reference to Cosmo
car year serial numbers or from the engine number (supposedly on front
cover of engine) to the car either. Earlier 20B cosmo cars supposed had
aluminum upper intakes, and the latest ones had a black composite
intake. I have never seen the composite intake on any imported engines
but there must be some somewhere.
PS please contact me at Cardmarc@midsouth.rr.com as I would like to ask
about some of the removed parts you may have.

My 20b came out of a 93 cosmo. The only numbers that I can find are B684.
This number is stamped on housings.   Aluminum intake manifolds.  Was hoping
to find a serial number somewhere tho....
