I have a 1990 thinking of putting the 5.0 v8 conversion in. Has anyone here done the conversion who lives in NY. If so how and what did you do for state inspection. I have read information from the state and talked to a few people but if you live in NY you know how that is.

 

Any help here?

Yes Thank you. I read those post as well. I was just wondering if anyone in New York has built a v8 Miata and has been through the state inspection process. Thank you again for taking the time to provide me with those write ups.

 

With a 90 you shouldn't have any trouble. Just have to find an inspection so that is willing to overlook things. It's 96+ that will be trouble in NY. I'll probably need a second car when I'm done.

 

In PA OBDI cars receive a visual inspection in all counties which looks for the same "type" of equipment that the stock Miata had. On a 1990 to 1993 Miata that is only a cat, on a 1994 and 1995 Miata you would also need an EGR valve (whether they work or not). In a Philadelphia, Pittsburgh and the surrounding metro areas you are also subjected to a "rolling" sniffer test in which your car has to prove it can be as clean as it was when new with an allowance for age. For an OBDII car (1996+) the car is plugged in and scanned to determine what codes it may or may not be displaying.

What this means for us in PA is that in the majority of areas you OBDI V8 miata only needs to have a bulge in the exhaust that you call a car and a EGR valve present. In the tougher counties you have to prove that your rebuilt 5.0 engine with new cats as clean as a 20+ year old Miata with close to 200K miles on it. Believe it or not, I've never had any trouble getting a V8 Miata to pass. While an OBDII V8 Miata can easily be made to show no codes making it display the correct VIN is a problem. The tech tends to get confused when his computer tells him the 1999 Miata he's plugged into is actually a 2002 Explorer.

I'm not sure if NY is the same but I though I'd offer this up anyhow. Good Luck!
