rb25 in a miata?

[miatarb25]

Hi my first post i have a rb25 motor transmission ecu and every thing to put it in my car and make it run. the only thing i wanted to know is what to do about obd2 for emissions on the car its going in is a 99 miata with obd2 anc ct plugs in to the obd2 emissions port when running the test i wanted to know what to do for this?

[eh?]

There's nothing legal you can do...

lol, rb and legal dont belong in the same sentence unless the word legal is replaced with illegal

you cannot make a rb25 obd2, sorry.

[miatarb25]

so there would be no way for me to pass emissions with the rb25motor in the car. also wanted to know what if i did an sr20 swap

there is nothing you can do with any JDM engine swap to make it OBD2 compliant since OBD2 is just the american governments way to stick it to us and nothing like it even exists in any other country around the world...the ONLY thing you can do is go buy a 95 or lower miata and change the exterior to appear to be whatever year you want...

nopebasically buying a japanese nissan engine that was never sold here will never be obd2 compliant.

sorry man.
