Hey guys, i did a little searching on the topic, but found mostly posts about jdm swapped engines or GSR's running Type R cams. Here's some background that relates to my questions. I plan on doing an engine rebuild on my B16A2 this summer with the following: oversized ctr pistons(81.25mm), a mild valve job, and ctr cams along with a ctr intake mani. I also plan on running a entry level piggyback fuel system like the VAFC or SAFC. With a mild setup like this what would I have to do to pass smog in CA? I talks to a mechanic who said that as long as i run oem parts (CTR or whatever) and set my fuel map back to stock, I would be able to pass smog easily. Is this true??

Thanks for you time, and sorry for being a noob

As long as you dont try to BAR the motor and the smog guy doesnt care about visual then you can pass. Is it legal, no.

nkkeisuke

what would cause my car to pass visual? the ctr intake mani?

Luserkid

Unless if the CTR manifold is the same as the B16A or ITR then that wont pass, VAFC wont pass visual. Without the VAFC or some kind of management i dont think youll pass the sniffer but im not sure.

If the VAFC concealed, will I be able to pass smog?? Also, are the ctr cams that running such a large profile that i'm unable to pass smog on a stock ecu map?

nkkeisuke

does anyone with similiar setup have any advice to give?

it is possible to pass smog in CA for a B16a with a ITR/CTR manifold. ive done it before

nkkeisuke

with the ctr cams will i be able to pass smog? would i have to run a separate fuel map for smog?

nkkeisuke

anyone??

If the tech looks at your ecu hell see the wires for the VAFC it doesnt matter where you hide it. But as long as you dont BAR or test only you should be fine, Check guys dont really car for obd1 cars. If its obd2 thats another story.

I bar'd my car with a vafc II hooked up. Just had it hidden. Tech didn't notice the wires hooked up to the ecu. But its probably better to just take it out just to make sure.

you wont pass unless you run some high octane gas. with the ctr pistons and a stock b16 ecu, the motor will be running lean. running lean will cause more NOx and CO. so no you wont pass either way. just know that when you modify your car with higher comp it will be very hard to smog it. just boost your car or something

damn....aiite guys thanks for the info, I really wanted to run a moderate NA setup, but i guess if i'm not going to pass smog i might as well go out on my rebuild

dose yhe vafc take away power from the vtec kicking in harder and what will i need so i can tune it on a dyno
