Can I pass smog with the 70mm Throttle Body?

Hey Just wondering If anyone knows if i will still be able to pass smog if I install a 70mm Throttle Body on my NA 4.0. Also if it will void the warranty. Ill probably keep my old one so I can put it back on if anything does happen so that shouldn't be an issue. Thanks

 

Ive heard a lot of different stuff on whether or not ill actually gain anything or what little I will gain, but every thread seems consistent in the fact that if you have other small performance mods: intake, spacers, etc.. combined together, the benefits can add up to something significant.

 

If you live in California, which it appears you do and it appears to be stock and nothing fancy, well yes. If it is visually outstanding in the inspection, then no, you will not pass.

 

Awesome thanks!

 

Clearly you didn't read my post. Let me repeat: spacer, intake, ETC... << that means things not included in the list. And do some research before you jump into the "snake oil" gang because there are benefits even if they aren't significant alone.

 

chill man, no need to jump down the guys throat. He's trying to help. jeez

 

Sorry to come off as a dick before and I can see now you know what your talking about however, much of my research has not been just on tacoma world as you can see I one of my posts in the intake manifold spacer thread of a link from another sight of what that thing actually does. Anyways I do actually plan on putting on a supercharger eventually so I was thinking of getting the other mode before that such as TB, exaust etc. however maybe I'll just wait until after. I appreciate your help because some info you gave me was actually useful.

Is a good website and more tune for engine modifications compared to TW.... even though TW is moving in the right direction now with more users posting about their experiences with SC, bolt ons, tuning etc... Hope that helps

 

The adapter dosent look like its tapered so I think it depends on the manifold inlet. I'm sure you can find that number somewhere. I'll check it out and post back

I can say the same about myself.

It's a car guy thing I guess.

 

Smog is a joke in CA. As long as you are not throwing any warning or engine codes, and as long as you don't look modded, you're good to go.

 

It's a question of pressure loss. The coefficient of pressure loss trough a valve (throttle body) is way more important than trough a reducer. So with a high pressure loss coefficient you want to reduce the speed of fluid circulating trough the items/accessories. So a larger throttle body is reducing the spped of air trough the butterfly valve and then the total pressure loss.

 

I agree. It's stupid. I used to be very lenient when it came to that. If I saw an intake like k&n or something I wouldn't care. Only time I would fail it is if it was something major like a new intake manifold, LT headers or something outstandingly obvious. Not that I wanted to. I just had to.
