I am curently looking at a S13 240SX with the 5 speed manual. And when I get it I will be looking to do the SR20DET engine swap. My question is will the SR20DET pass emissions? I've heard that it will not pass. So would it be smarter to just get a SR20DE engine and then just toss in an aftermarket turbo and have a custom SR20DE-T? Thanks for your help.
Will the SR20DET pass emissions?

Found it.
http://www.epa.gov/compliance/resources/policies/civil/caa/mobile/engswitch.pdf
Page 2, second to last paragraph. Implicitly forbids SR20 swaps. Not that I give a damn, I'll do it anway..

·The sr20det engine will pass emission if in stock form, but not the visual inspection, unless you take the car to a referee station and he approves the engine change, in which case it will be a legal engine. He will change your underhood label to match the sr20. here is some info i got from nismo's website about the sr20de and sr20det.
The DET has oil squirter piston coolers
The DET has a bigger oil pump.
The DET has a different front pulley.
The DET has lower compression pistons (8.3:1 vs 9.5:1).
The DET has bigger injectors.
The DET has direct ignition.
The DET has a variable intake cam, runs retarded at idle, advanced mid range and retarded top end.
The DET has mechanical shim in bucket type lifters with a slightly bigger in duration exhaust cam
As i understang it the DET also has stronger internals that can handle up to 450 horsepower.

what is a referee station? do you have to have them approve the engine swap before you install the sr20det or before? how much do they charge? do they make you do anything to the engine like take out the turbo to make it legal? sorry about all the questions but i gotta know, the sr20det is the main reason why im buying the 240sx

·Ok it's like this. The referree is not guaranteed to approve your engine change. But it's not impossible. They wont make you take your turbo out. They might tell you to add an egr valve(just an example) or some stupid things to make it legal. They will do an emission test on it. Then they will decide. I dont know how much they charge. I got the engine info from nismo.org, and i got the rest of the info from my head,I have a smog license.

·you're a moron
well thats why i came to this forum, hoping that i can learn more. but for you guys who do have the sr20det, what the heck do you do when its time for you to have your emissions checked out? i mean, bribing cant work all the time. legal or not im still getting the swap done.

Dude, I called the EPA to get that info. No SR20DET is street legal. I dunno where you got that.. but call the EPA yourself if you don't believe me. No "referee" can approve an engine swap that's not legal. Did you even read thee EPA link I posted?

·i just gave the steps to getting an engine change approved as taught to me. If the EPA says no, then why inquire further. And no i didnt check out that link. and Dousan im sorry for calling you a moron.hehe
it wont happen man. its an illegal engine. simple as that. its not EPA approvated. its not DOT approved.
i dont know who taught you and hopefully its not something you read someone posted online but rather thru FIRST HAND expirience and not word of mouth.
if that person REALLY DID do it..then that's something to dig deeper about.

that bull cause my 72 nova had a completely different motor than stock and it passed the visual inspection AND the sniffer test. plus ive seen guys with an LS6 in thier 80's camaro and they pass fine. so if you guys are saying that it is illigal because it didnt come in that car that cant be it.kkw4p said:
so there's nothing you can do to pass emissions legally? even with a (saw this somewhere in this forum) catalyzer, full exhaust and ethenol in the gas? (what is ethenol? remember i just started out in this auto stuff. forgive me if i sound dumb, hehe)

·ok this is the last time im gonna say it. in caps.
I GAVE THE STEPS TO GET AN ENGINE CHANGE APPROVED AS TAUGHT TO ME. also i can't see the damn epa link cause adobe reader froze my computer. Now i have never tried to get an engine change approved. I also said it's "not guaranteed to be approved." But then again there are people selling 240's with sr motors and they claim to be smog legal. So why dont you go ask them about cause i've told you all i know. It says right here in my book.
"The BAR referee label is used to provide engine and ECS information for unusual "non-standard" vehicle configurations.
Provided the vehicle is equipped with a BAR referee label, a technician can inspect SPCN and grey market vehicles, vehicles with engine changes and vehicles with other non-standard configurations."
"*The engine and emission controls must be certified to the year of the vehicle or newer, and to the same or more stringent new vehicle certification standard.
*Do not mix engine and vehicle classifications that degrade the emission certification standards
(this is where all previous attempts must have failed. The stock ka probably runs so clean that the sr, as clean as it may run, burns more fuel cause of the turbo and puts out more emissions)
*The installed engine and host chassis must retain all of their original emission control equipment."
There is more but im sure your bored by now. This is some of the info out of BAR's Revision 6 Manual. I wish i could see a list of the EPA non-approved engine changes because my adobe reader doesnt work. For all of you out there that already knew the engine swap was not going to work, i didnt and i based my judgement on information that i already knew..and i was still correct based on the fact that i didnt know the EPA had already shunned the sr swap.

are you slow? it may PASS but it wont be LEGAL
passing the emissions does not make the engine LEGAL. maybe smog legal but not legal to be in the car
if a cop pulls you over you cant say 'oh officer, i passed emissions though' why? because its not DOT approved. its not EPA approved. its ILLEGAL.
got it?
