Yes, the B20 is a truck motor, yes, it is an illegal swap. Conventional wisdom would agree with you, however, we use propane gas to pass any engine swap in any car. There are legal ways to smog a B20. Read on......

Illegal B20 swap + propane gas = Alternative Fueled Emissions compliant engine swap. Alternative fuel is the key word here, forget the motor swap, with Alternative fuel, it is all about making the swap run clean. Even if the engine swap is a turbo GSR, Standalone with ITB's, once it is run on propane, all the performance mods are now legal because you can argue that the GSR, turbo, Standalone and ITB's are needed to take advantage of propane's 110 octane rating. This is cutting edge here, just because this is a loophole that is not commonly used, doesn't mean that it is BS.

Keep in mind that, once you remove the propane and re-tune your setup to run on 91 octane pump gas, you are no longer 100% legal, but wait, there's more.... here is the good part.... the BAR referee sticker in your engine compartment doesn't specify fuel. So, when Johnny law does pull you over, all they do is scratch their heads and wonder how you BAR ref'd a turbo GSR, Standalone with ITB's....

Besides BAR reffing your engine swap there is another interesting loophole that keeps Johnny Law off your back, it is called smog exemption, this exemption is a one time emissions test on propane that certifies your vehicle as an Alternative fueled vehicle and smog exempts the vehicle FOREVER, with smog exemption, you will NEVER have to smog your vehicle ever again, even when you sell it. Smog exemption is a legal loophole that smog exempts your vehicle forever, no more fooling around with shady emissions shops.

If you look hard enough, there are legal loopholes for everything. Laws, mandates, regulations and government protocols are written by attorneys with legal loopholes and/ oversights written in, that allow everyday citizens to drive, smog, register and import any vehicle ever made on the face of this planet.

For the record, smog exemption, carb exemption, and BAR reffing are 3 completely different processes, these terms cannot be interchanged. BAR reffing, by far, is the most difficult and useless certification. Smog and Carb exemption are far better than a BAR ref'd swap because a BAR ref'd swap still must undergo strict emissions testing, while the smog/carb exempted vehicle doesn't. Also, Johnny Law can ref ticket a Bar ref'd car, but not a carb exempted car. The simple definition of a carb exempted car is a car that is exempted from all carb emissions mandates. Basically, local law enforcement can pop your hood, but, because the vehicle is both smog/carb exempt, it is therefore emissions compliant regardless of what turbo
k20, GSR or b18 engine swap you may have, a smog/carb exempted car can legally drive around with a fully built turbo GSR with no emissions controls, and never get a referee ticket."

curious how legit this is, and if it really works.

 

propane?

 

so basically this article is saying: if you convert your car to an alternative fuel source that isn't gasoline, you get an exempt sticker for life.

I don't know about the legitamacy of that - seems wierd someone would go through the effort to write that if it were BS though. Wonder if that works for ethanol too. I have not heard of any subies running on propane

 

ahhh Honda-tech, always amusing

yeah theres ALOT more to legally converting a car to CNG/LPG
heres alot of good info.

theres alot of kits out there available to do the cpnversion but last I heard to actually get a car full CARB compliant would run you several thousand.

 

haha.. that is all
