jdm b16a Emissions Test
I've been trying to do my homework on passing emissions with a b16 engine legitimately? I see mixed answers, some saying no they will not pass and others saying they passed. I've also read things you can do to pass like beating it on the highway? Is this true, or is it nearly impossible to pass with a jdm b16?

It's possible to pass it if everything is in running order. And no cels are going off.
I know people and my mechanic told me that if you go on the highway a day before or that day really moving the car making everything work does help if the car is used more on city driving.
I know myself and others will say just find a place to just do it. If you know what I mean lol.

A working cat will definitally help, go for a ride on the highway before the test to get it upto working temperature. Clean air filter, some fresh plugs and a factory tune should pass no problem.
Some people say a fresh oil change can effect emission test results, i've never really experimented in that regard.

E-test
Hi everyone is there gonna be a problem to pass the e-test if u have a swap engine but same b18 engine as the stock which is different serial number between the vin no. And the engine and my friend of mine told me that it might not pass tnx

I don't get this people saying "they will or will not pass" meaning; they all will or won't pass. That doesn't make sense.
It depends on:
-type of cat and it's condition
-condition of the engine
-how well the engine is running/tuned
If you have larger diameter exhaust/cat and it's a high-flow cat, it'll have trouble getting hot enough to do it's job and the core is not very robust.
If you have an oem type universal or stock cat in good condition, it's will do it's job well and help the car pass.
If the engine is running like crap or is not running on the correct tune (swapped engines running aftermarket or chipped ecu's, then you'll have a hard time passing.
So if you want it to pass, make sure:
-you have a good quality oem or stock type cat, or high flow cat with smaller diameter piping.
-Make sure your engine is running well and has the proper ecu/tune to run on.
-As added assistance to help it pass, retard the timing as far as the dizzy will allow. It'll be gutless and have less power, but it'll reduce all emissions significantly. You can just put it back after the test.
Beating on the car before the test is not necessary. In the time it takes for you to go in the shop, give them your keys and have them bring the car is could be a while or it could be right away. I'd suggest to run the car hard and get the cat hot, but don't over do it.

It will be chipped [hopefully], though ive seen some cars with completely wrong ecus still run quite well, as long as it has the right software in the chip that is in the ecu, you should be fine.
retard the timing a little, make sure the car is running good, cat is healthy, warm up the cat before the test and you should be good.
