Hello all: I'm new to the 914 world and am hoping to add a 2.0 to our garage soon. I have seen references to a VIN page in the forums but can't find it on the site.
Can someone point me in the right direction? Thanks |

found out a little bit more on japanese and australian emissions regulations.
australia introduced ADR27 for calendar year cars 1974. japan had very similar standards in place for calendar year 1973. both countries modeled the standards (reg) very much based on USA emissions standards that had commended in 1970 calendar year (ie late 70MY early 71MY usa market cars). cars for japan and australia were to be equipped with evap system, closed crankcase ventilation systems (pcv) and also meet tailpipe emissions for set standards of NOX, HCPPM and CO. the important distinction was that neither japan or aust had a tight time line set for unleaded fuel introduction. in australia's case that does not come into effect until 1984. not sure on japan deadline date but its sometime well after 1973. hence cars for japan (and theoretically aus) could retain high compression engines running on higher octane leaded. it was unleaded fuel that caused the primary drop in performance in USA market cars as compression ratios had to be lowered. so - a J market 73 car had to have PCV, EVAP System and meet tailpipe emissions probably very similar to USA 71MY cars. i haven't found a 73 J market car with sufficient documentation in original condition to verify the EVAP system inclusion. however its clear from @dr914 's limited documentation that the matsuda 74 LE does have it. its also an insight into why misawa might have dropped the 1.8 from its imported range in 1974. at that point the ROW 1.8 was a twin carb high compression motor with no emissions gear tailored for euro market. it would have been extremely unlikely that it could have passed 73 J tailpipe emissions in its euro form. as an alternative the L jet 1.8 was an unleaded fuel car well down on power. so they just gave up on that one? the 2.0 L euro high compression engine would have been tweakable on tailpipe emissions standards yet still have retained its higher euro power due to higher compression. its also the explanation for the 73MY cutoff for crayfords rhd converted cars for private import into aus. the crayfords business model was in alliance with malaya motors UK and cars were UK spec cars set up for UK regs (headlights, etc). as such did not meet ADR27. no EVAP and likely non compliance with tailpipe emissions = end of the road for a private import RHD 914 for australia. (note cars had to be RHD in aust). |
