perfect, i was going to ask the same question. i have a 96 civic dx, and i want to swap in a b16. i have read a couple of things saying that it has to be from the same year as your car or newer. how would the markings on the engine prove what year it was from? also would the new engine pass the sniffer test? and isnt the b16 and obd1 and mine is obd2? and how will that work. i also live in cali and would like to swap my motor. if i were to do so, i would get a usdm from hmotor. they say it has everything for a complete swap....if i just use the stuff that comes with it will that pass me with the state ref? thanks guys.

 

I think it's illegal but don't quote me.

 

I have done a swap in Cali but on a ford ranger. As long as it is from a car (civic, accord, prelude, etc..) and is from the same model year or newer, and you have all the smog equipment on, it will pass at the state ref. So basically, it has to look like it came from the factory even if it didn't. It is not so much the marking on the block, but the equipment attached, mainly smog. My swap was a 02 3.0 into a 99 4 banger. Since the 3.0 was available for my truck that year, my swap was easy, pull it out, drop it in, they even were a little easy on me becuase the the 3.0 for 02 was different in that the intake a few sensors weren't there that the 99 was suppose to have but I made my 3.0 look like how it was suppose to for 02 so they didn't care. Just make it look stock, don't cut corners on the smog and you'll be fine.

 

here is a website that kinda gives you an idea on what you need to do.

You'll need a 97 LS motor or newer.

Make sure the block numbers are all from a passenger car. B20's are not allowed (truck CRV)

Make sure all your emission equipment is attached. (PCV, 02, blah blah, etc.) For OBD2, there are more things required than OBD1.

Make sure you have a catylitic convertor.

Make sure any aftermarket bolt ons have CARB numbers made for the engine clearly visable.



All in all, try to make the swap as clean and as "stock" as possible. You should not have a problem. All you need to worry about is passing the sniffer after the visual test.

I have had my swap BAR'd. It feels great driving around with a "legal" swap.

 

From my understanding which I was told from one of the test only stations(Um correct me if im wrong)...if it's a civic motor (b16a meaning civic motor) and it's going into a civic chassis than you wouldnt need to have it state ref'd. But if it's an integra motor going into a civic chassis then you would have to get it ref'd.

It's just like throwing a 93 d16z SOHC Vtec motor into a 93 DX Chassis..it's still consider a civic motor.. you just have to have all the emmissions hooked up though. A few of my buddies did it and it passed. one of my buddies car had a (Del Sol) b16 USDM obd1 swap into his 92 dx hatch and we got it smogged w/out having it taken to the state ref's for inspections. Another had a 94 LS integra chassis and threw in a 95 gsr swap w/ all emmissions and it passed as well w/out state ref invovled.

 

All your examples are from close year, same chassis vehicles. For example, if you swapped a 99 motor to a 93, you gotta have it checked by a ref or you are gonna get sent home by the smog station. Swaps from the same chassis designation from what I have seen do not require it to be taken to a referee station. Besides, why pay the 60 bucks to go and hope it passes at a smog station when you can go to the ref for 40 and get it smogged if it passes or know why you doesn't. Smog stations won't do that for ya!
