If you live in california HOW did you pass smog with an sr20det engine in your car.

-originally posted on freshalloy... and im searching right now :ghey:

I know this topic has been discussed to death, but I checked the best of 240 forums (EVERY PAGE) I found like two or three topics discussing smog in CALIFORNIA... Arad said it best that the engine was never legal. But I KNOW you people KNOW some people who have passed smog, and have registered your cars. So I am curious as to what tips anyone might be able to give besides the fact that I would have to go to some shop that just totally runs a shady deal to get my car passed.

There is a nice helpfull explination concerning swaping engines(below)... As we all know the sr20det was never a California certified engine (possibly something may happen due to jdmevolution.com) Since they are selling state legal s15's and to do that they have to be approved or some silly mess, they have s15's in them so if they are not sold as kit cars or off road vehicles but are made road legal like skylines are I believe. That means they can be registered which means the sr20det engine would be california legal since its a california based company... this is totally my assumption.

Anyway have at it brainiacs... I plan on buying an sr swapped 240 in the coming weeks and im wondering how much fun this is going to be going on a goose chase to smog my car.

Replacement Engines:
Entire engines can be replacement parts. As with any other replacement part, the engine must be identical to the original. If the replacement block or engine is obtained without emissions equipment, all the equipment from the original engine must be installed on the replacement block.

If the engine is not identical to the original then it is not a replacement part, instead it is considered an engine change.
Engine changes are a modification that must meet certain requirements to be legal (please see "Engine Changes").
Japanese Replacement Engines

Used engines imported from Japan can be used as replacement engines as long as the engine being used has been identified as functionally identical to the original engine. Please refer to the engine importers catalogue to determine if a replacement engine is legal for installation in your vehicle.

Engine Changes
Engine changes are legal as long as the following requirements are met to ensure that the change does not increase pollution from the vehicle:
The engine must be the same year or newer than the vehicle.

The engine must be from the same type of vehicle (passenger car, light-duty truck, heavy-duty truck, etc.) based on gross vehicle weight.

If the vehicle is a California certified vehicle then the engine must also be a California certified engine.

All emissions control equipment must remain on the installed engine.

After an engine change, vehicles must first be inspected by a state referee station.

The vehicle will be inspected to ensure that all the equipment required is in place, and vehicle will be emissions tested subject to the specifications of the installed engine.
