You'd be surprised what get's by even the ref! Most refs in CA would pass any hondo motor in a honda as long as it fit certain criteria, such as 1) displacement 2) OBD regulations on that year's model (has to be a US spec EMC because it will show up as JAP on the test)
That's pretty much it. If you took a B16A and put it in a CRX and changed the valve cover they wouldn't be able to tell the difference.
The REAL issue with putting a RB motor in a Z is that all RB motors are OBD and the Z & ZXs arren't OBD at all. So there would be alot of hidding involved....
So is the RB30DE cross flow. Never mind, don't answer me. I'll do my own research.
I'm not sure how they check displacement. I remember when I got my ZX smogged at a ref he said "what size motors are these supposed to have?" And I said "2.8" and he said "man, they really gyped people, it came up quite a bit under"
I know there's a bit of information they take from the underhood stickers. I wonder if that's where they get the cc rating or something.
Well, poker is calling. I'm still going to contimplate this install if I decide to keep my ZX for the long haul.
