My 77 blue B210 took 2 1/2 years to be restored. I wish I could post pictures it came out beautiful. I live in a city where there's no emissions test required but since my Datsun had previously failed emissions with the previous owner, I needed to take the car to a city where they do emissions so it could clear and I could register it back home. Bought emission components here and there even had an original air cleaner box shipped from Europe at an outrageous price but had to do it. I Took my Datsun for emissions testing last week ago and it passed with flying colors I was even congratulated for having such a clean breather. Now I'm thinking of removing all emissions components since I don't need it where I live, no emissions testing required, it was a one time requirement so I could register it. Any thoughts as to where this could be a good or bad idea? removing all emission components.
