ok i got a CA barred b16a3 (1994 doch vtec del sol motor) in my 1993 honda civic. if i switch out my bottom block to a b16a2 bottom block w/ p30 piston and rods (jdm sir piston and rods), nippon racing piston rings, acl bearings, and arp rod bolts. i will be using my stock head and putting it back on this bottom block. my question is would i still pass smog with this bottom block in CA? since this would be on a usdm block not a jdm block just with jdm parts im assuming they wont be able to tell its the jdm piston and rods.

 

it all depends how rich you're running.... about 6 months ago, i got my friends ek bard with a b16A2 99 EM1 motor and then 2 months later replaced it with a rebuilt jdm b16a block with a ctr piston and it barely passed... smog techs dont check for that kinda stuff trust me, i do that chit all that time... if u cant pass then hit me up =]

 

my only concern is that if they read it as b16a2 they would say it's obd2 cuz my motor is ob1 right now being b16a3

 

i doubt they will, like i said most smog tech wont even look they'll just scan the bar sticker and then look that the engine for any mods then smog it... btw u get the muffler u needed?

 

Depends on the tech. Some techs are finnicky then others, Do you have a really good cat?
running a higher compression will raise the nox level.

wouldnt they put in the vin# from the bottom block? if they do then it would read that it is a different motor wouldnt it? yeah i found a muffler already thanks tho.

 

im not too worry about the cat if it's bad. i can just get another one and weld it on if that is the issue.

 

Most time if u have a sticker, ill just scann it instead of punching it into the computer, that takes too long... just go do it, where do u smog ur car at?

 

go to some cheap mexican shop. never fails.. and thsoe no pass no pay places. they WANT you to pass ;]

 

i used to smog my cars at some vietnamese guy in modesto but i just moved up here to sacramento so ima have to find a smog place. will i dont have to smog for like another year or so. i just want to be safe for the long run.

 

I passed smog in my car. Took me four tries though. Jdm itr pistons, 2 layer head gasket in a gsr. Tech just do a visual on the car and smogs it. Like integragsr said. They scan bar sticker and visual and smog.

 

what did you do differently to pass it the 4th time? since you said it took 4 tries

 

^slipped the tech a 100 to call it a day hahaha jk

 

I double cat my car and place de natured alcohol. My car was running to rich. I was also running a jdm itr header too

 

like i said if u cant pass it then lmk

 

What does your BAR sticker say?

 

yeah i will let you know
