was wondering if i buy a stock z6 with a p28 and put it in my ek if it will pass smog. my current y7/z6 didnt pass and has a blown headgasket. need answers pretty quick because my smog due date is coming up

 

it wont pass with a p28 because thats an obd 1 ecu. The problem is that they plug into the ecu port to check for the readiness codes that the obd2 ecus produce. Since the p28 is obd1, it wont read anything.

what you could do is OBD 2 p2p ecu from a 96-00 sohc vtec and use that. Of course you would have to use OBD2 injectors, and distributor, and do the trick to fool the ecu in seeing the crank fluctuation sensor.... so that there's no check engine light

 

Probably less headache to go with a D16Y8.
It's against the law in California to put an older motor in a newer car, D16Z6 is 92-95.
also, as Wazup says you have the OBD version issue.

 

I believe you won't pass. Old motor in newer car is a no no in CA.

I suggest just swapping in a y7 in or y8, get it done. Either that or find someone to spend $200+ on to get you smogged.

 

it will definitely not pass! my friend tried, got rejected before they put his car on the machine..get a y8 or y7!

did your friend use a p28? my theory is that with sohc engines, a smog wont technically know that its an older engine and will only care if it will read the readiness codes. so as long as you use the proper obd 2 conversion (injectors, distributor, CKF trick) it should work.

 

yeah he used everything stock from a 94 civic ex, everything from harness, to ecu, and intake..yeah didnt pass at all, and he went to the one that we considered to be the more lenient one...but you sure can try tho

 

dang that sucks. i guess ill try to find another y7 or a y8
