Thread: outfitting the SR20VE with functioning USDM EGR system

I'm looking for the best way to temporarily outfit the SR20VE with a USDM intake and exhaust manifold complete with EGR so as to fully pass emissions in California. I've read a number of posts on how to simulate EGR sensors, however I need to have the real EGR system functioning to pass. I did read that someone was once fabricating a setup for the VE, but seems like it was never completed.

Is anyone aware of a USDM setup that will run on the SR20VE longblock? I have a high port SR20DE which I suspect will not work. I also have a GA16DE which I am considering as a test case but I don't have the VE motor yet so I cannot determine the fitment. This is for a temporary setup to pass emissions, and so there is no concern regarding the loss of performance.

Has anyone had success with swapping the manifolds? and I think it would also require running the ECU of that USDM motor - can anyone shed more light on this possibility? Thanks -

Cali requires a visual inspection, that's what is going to hurt you. Other states allow the egr to be bypassed by using a resistor to keep the check engine light from being activated. I've been on the old forums and even the SE-R Mailing List bavk in the day and I've yet to come across a retrofit of the USDM EGR system to a VE. Not to say it can't be done but Cali is making your situation difficult to suceed. Good luck.

I"m trying to avoid swapping the motor every 2 years with a USDM engine for smog.....there must be a better way -

i'm not american.does the motor actually need a egr valve to comply?

if no, could you consider a tunable ecu or standalone ecu, with a smog-complaint tune for emissions, and a performance tune for the other 364 days? (like vw lol)

I've been thinking about doing it on my 02' auto turbo car if I ever blow up the RR engine. Would only need to modify the upper intake for egr and a bung in the turbo manifold. Would take some fabrication but anyone that can weld aluminum could do it. You could probably get away with tapping and using AN fittings and bending line if welding isn't an option. The EGR system is actually pretty simple and external so it's pretty easy to modify and adapt, that's why I just kept it functional on my car.

Moving your HP intake to a VE would be an option, but I'm sure there would be some major modification involved. Probably would need to have an adapter plate CNC'd to make it work.

yes in California it needs the valve and connection between the exhaust and intake headers -

I live in cali, there are a few zip codes which do not require smog. My car is registered to a ups store mailbox in healdsburg which does not have smog. I simply pay registration fees and get my sticker. No inspection, no nothing. Do your homework and avoid smog entirely. In norcal, no smog starts at sonoma county. In socal, there are parts of san diego county that dont require smog. The dmv even provides a page where you can look up which zips require which smog type. The dmv website will provide you all the tools and info to do the same so long as you look, click around, and read. For mine its transfer of ownership only, and i was smogged before going ve so im good to go. Anyone who tells you this is bs, im living proof that it works. Just got my 2017 sticker last weekend, havent smogged in 4 years.

that is brilliant - something to consider - but I could have some issues with it as well being that I live and garage so far from those locales -

this might be a good way, and would also have to consider all the other needed emissions components, but ultimately would probably work. I'm going to see what kind of modifications to my highport emissions gear would be necessary to make it work on the VE.

Ups store renews over phone and forwards your mail upon request. Only need to visit them once.

These counties contain zips with no smog according to the dmv website:

El Dorado, Placer, Riverside, San Bernardino, San Diego, and Sonoma.

This is the link to check the zip

If you are smart ypu can move your insurance to the same address as generally the smog exempt zip codes are in the boonies so insurance cost goes down. Moving from la to up here went from 180 a month to 48, and when i moved to smog exempt it went down to 27 with no other changes other than where its registered.
