Whats up guyz? Ill get right to it. I have a built engine ready to go in my 95 240. I just found a 96 5 speed for cheap thats been totaled but all body pannels have been repaired. Now I live in NC so 95 on down does not have to pass the sniffer. So I can do what ever. But for those pushing 400hp plus in a 96 pluse do you have a problems passing inspection?

My kade-t will be a 400hp daily driver. I haven't decided on what engine will be going in the 96 but I will tell you it want be pushing less than 400hp unless you guyz tell me it want pass inspection. When Im done One car will be kouki and the other zenki. and thats my goal to have both.

The 96 will never pass inspection, legally.. Regardless of your hp levels, installing a turbo kit will make your car fail.

read up on local laws to see if the car falls under the "old car" rule where after a certain age, the car no longer needs to be smogged. if that doesn't work, you may want to see if any surrounding states have more lax laws. you can pass a sniffer test but visual inspection is going to be tough. i honestly have not went through this process as we have no emissions tests in FL anymore..............

OK, first things first. A car can be capable of making 3 million whp on boost...just turn the boost down and you're at a reasonable level. That make sense? In other words, you're not WOT on 25psi when you take the emissions test.

If the car can pass a visual inspection, then you can get it to pass emissions EASY. But you need to find out if they are going to fail you for having the turbo kit installed. The emissions is the easy part man.

Find out and get back to me.

With an OBD2 car they dont even run a tail pipe emissions test. 96 and up they just hook a OBD2 code reader up to your car and pull the codes. ANY code stored in the ECU will cause you to fail.

So that leaves you with some serious issues if you hook up a turbo charger. One being the EGR system. The other being the Evap emissions system. EGR can still be utilized, you just have to get pretty crafty. Evap emission system is going to be the nail the coffin. All the sensors and check valves are going to start acting really weird the first time you go into boost(or they will just fail). Just going into boost the first time will most likely cause all kinds of OBD2 codes.

Not to mention, with a s14 obd2 ecu your options for larger injector control and tuning are really limited(AFC's..). If you swap it out to a OBD1 ecu so you can run a chipped ecu, you will automatically fail when the tech hooks his scanner up to the OBD2 port and trys to pull your codes.

Actually i was dead wrong, there are people who run obd2 ecu's with a turbo setup and dont throw evap codes.

You still wont pass visual.

You can reset the codes via toggle switch though IIRC...while sitting in line waiting to be inspected. I did so on my Celica many times.

The visual will always be there to f*** the motor enthusiast

I've been going to the same shop that is a mom and pop style smog place for about 5 years. I send as many people to them as possible and tell them to make sure that I sent them, so that way when I go they cut me alot of slack. I also send customer's cars to them. The first time I went I told them that hey my car is turbo'd, but it runs super clean in and out of boost. The guy put it on the rollers and did the low and high speed tests and said damn man this thing sniffs like a geo metro, I started laughing and been going there for 5 years. He is also into Mustangs hardcore so I bs with him alot about them.

Why would a smog tech ask about a toggle switch? Don't complicate something that is simple.

im a liscensed inspector so i have no problem getting my car to pass but if you reset your ecu there will be readiness tests that arent complete at least here in NY and will then fail you. ive inspected blown c6vettes and passed without a problem. and ran civics that passed weihtout a problem and they were modded.
