so i just learned today that you can put JDM engines in your car...i am overjoyed...i know you need the exhaust manifold and the ecu...but what is the nessesary smog equipment?

 

get a helms/chilton manual and look over all smog equipment you will need ... there is way to much stuff for someone to actually tell you..remember if you want to stay legal.. you have to get a same year engine or newer... so if u have a 96hb.. and u get a 96 JDM engine then best and easiest way to figure out all smog parts is to get a 96year or so manualfor a GSR and look over all parts for smog equipment you will need..good luck
