will i ever pass emisions
i have a 77 280z i bought about a year ago and it's time for me to renew my tags. so i was looking at my engine and the previous owner put a header on blocked off the egr took off the cat and there is no O2 sensor. i put a cat on that i got from my friend and took it though the deq test it failed. what do you think i should do to get it to pass?
I'm currently collecting parts for a turbo swap and i was going to run megasquirt if i put ms on now could i get to pass?

First of all it would help if we knew in how you failed. If it was you NOx, then it is no doubt due to the fact that the EGR is blocked off. But we need more info before we can give you any good advice.

my car passed flying colors with the egr dissconnected. all you need to offset that is a bottle of methyl hydrate, plus fill up your rear tires, it helps reduce drag on the dyno, thus creating less rolling resistance, also you can unplug #5 injector if there is no visual inspection, the #5 acts like a air pump, and runs on only 5, then it helps to lower the emmisions. it may sound odd, but all this stuff works, i can get and l28 n/a to pass with these simple tips, also raise your idle to 1000 rpm. try it, and post more info if it still doesnt pass

So do this:
-Install a cat
-Make sure the timing is adjusted correctly (or even retarded slightly)
PS... When I took my Porsche to emissions, the HC was 21,000ppm. OOFA!!!

That year didn't have an o2 sensor anyway's... If it's running that rich, it's either your AFM, Water temp sensor, or possibly a bad fuel regulator (Most likely not though) or really bad fuel injectors...
