Thread: Possible smog 'legal" conversion for SRVE motors.

first off this is for people in states that actually have smog tests.

hey guys ive been developing an EGR (exhaust gas recirculation) system for the ve motors. as you should know these motors do not come with egr and therefor are an illegal motor swap to have in your chassis. and since there is no usdm manifolds that match up to the ve there is no easy way to get it to pass a normal smog test.

is this something that you would be interested in buying to make your car smog legal?

Which exhaust manifold do you use? stock DE?

A header with a heat shield. How about the EGR sensors?

i pass smog, my friends pass.. not sure about them cali guys an how they do it tho?

We pass very carefully lol. WA smog and Cali smog are very different. The smog Nazi's don't like anything that isn't 100% stock. The VE will pass but there is no EGR valve so that is a huge tip off to them it's not stock. You enter the fail boat at that point. You have to get lucky the guy will look the other way since it passes the rolling dyno test. Luck won't last forever.

then i think this could be very helpful for cali guys for sure and i change my vote to yes then lol..

the thing is i think you would basicly need a whole new plenum or a seriously modded one, then all you really need is ALL of the stock usdm sr20de emissions stuff, and a ssac with a heatsheild should work fine i'd hope lol


up here in WA a lady popped my hood cause my cig lighter dont work so she had to get signal from the spark plug wire, she was like.. OO SHINEY! i about shit my pants an was like, yea im a car detailer an i like to keep my stuff clean.. lol she didnt say anything after that. car passed tho

a properly tuned VE will pass cali emission but its on the high side and smog guys no adays are way scared the state has been cracking down hard.

as for the manifold it will depend on how i sell the kits. any after market header can have a bung added and most ssac are like stock so either having some one weld in a bung or ship the header to me for the modification.

the actual egr system is quite low tech. im using all factory parts and will even use the factory harness in most cases. i know the kit wont work for everyones set up but will be an easy mod to make any of them work. there is only a few parts ive actually had to make but were not very expensive or hard.

the factors i cant control is if people still have the egr parts or if they have stripped the harness. good thing is every part has been vary easily available on the classified section. there are still plenty of new parts also, they will just be the more expensive route to go.

the main issue is that its going to look like ill need the lower manifold shipped or dropped off for the modifacations. i am planning on selling it as a bolt on kit or as a DIY kit where you can have the parts welded and installed.

this are great news mac !

I agree, good news here.

You guys wonder why my engine bay always looks like a mess? Because around here I have to pass a visual and OBD2 test. When it comes to the visual, they see everything... everywhere.. "ok whatever"

lol

The primary purpose of the EGR system is to lower NOX levels. But NOX is not the only pollutant this is checked by most states. Through testing in the State of Maryland, I found that retrofitting a DE AIV system to a VE is both easy and effective at reducing all three pollutants measured. At the time I did this, Maryland was using the standard roller dyno test for emissions testing (now they use an idle test). Here are my results with and without AIV on the roller dyno:

..................State Limit..........W/O AIV.............With AIV
HC..................1.0...................1.6.... .................0.8
CO................20.0..................16.8...... .............11.9
NOX................2.2...................1.8...... ...............1.2

More details are available in this thread: http://www.sr20-forum.com/vvl/13220-sr20ve-aiv.html

If you must pass a visual inspection, that's an entirely different matter. You will need to have an EGR system installed (or apparently installed) on your engine. But, if it's just a matter of passing a test, AIV may well do the trick (note that my VE never had an issue with NOX, only HCs -- this was the case with a variety of bins and test conditions).

I hope that this info is helpful, even though not directly responsive to the original question.
