Hey guys, I live in Salt Lake county in Utah and just learned that even with classic plates I will need to pass emissions. Some people register their cars in different counties to get around this but I don't want to do that. Some local E30 guys said I should still be able to pass "as long as I get a decent cat and a proper tune." Does that sound right? They also confirmed that pre-96 cars "only need to pass a sniffer." I am willing to invest in a good high flow cat if that is what it takes to pass emissions. Just want to hear some more opinions.
My planned setup: 2.7i (stock ETA bottom end + 885 "i" head) with a turbo, though I am also considering swapping in i pistons and shaving the block to boost compression.
