^ The O2 sensor mounts in the exhaust usually in the header. The moddification needed on an aftermarket header is usually to extend the wires of the oxygen sensor to reach the bung on the header. Aftermarket headers usually have long individual runners for each cylinder and come together further along the header than your stock manifold (which pretty much just comes out and together imediately). That's the only real modification needed to make a decent aftermarket header work w/ your car. Unless your state are real nazi's (i.e. California) I don't see why having an aftermarket header would imediately fail you on an emissions test.

But what do I know...I live in New Mexico (No emission controls)

Supra91 mentioned something about making adjustments or something to that nature. Now that I think about it, I can't even remember exactly where I installed the sensor. Was it directly on the manifold, or behind it on the block. I did it in the dark with a dull droplight. I think it was the manifold, so a header would have to have mount, wouldn't it.

sorry for not replying sooner

anyway...the pacesetter header(i don't know about the obx one) doesnt have the o2 sensor mounting location of the header itself, its on the extension pipe that connects the header to the rest of the exhaust. if you wanted to you could drill a hole into the header and mount it there.

the o2 sensor does mount on the stock header

I've gotten it up to 140 mph on the highway. Plus, the engine compartment is cramped with enough stuff as it is. I've seen turbos and I would hate to work around all that plumbing. I've never driven a turbo. Is there that much of a difference? In 1989 Motor Trend did a "Top Ten Shootout" of the fastest cars for that year, and they got the Turbo Supra up to 146 mph max. I've come pretty close to that in my NA. Is the difference in the lower ratio's? Anyway, I'm very happy with my car and I love these boards so I think I'll stick around here, If you all don't mind. It seems a lot less snooty here at home.

Sincerely,

Scruffboy

You kno they just added a 7M GE section right? I've been there since Jan. Everyone there has a really good sense of humor and can answer a lot of things. Except there is one really heated thread in off topic right now that I've been trying to lighten up. It worked so far until the other 2 that are fighting start posting again. If you want to feel like you dont even have a supra, go to supraforums.com. It's like, if you have a MKIII then you dont have a supra and be prepared for the worst flaming and sodomization of your life.

Hey, I see you have a Tiburon for daily driver. I was thinkin of getting one of those myself. I never owned a new car and the price is reasonable and I have heard good reviews. What do you think? I would get the GT 5 speed. The 6 is like another $2000. Give me your input as I would very much be obliged.

Actually its a fun little car for a 4 cyl. I wanted the GT V6 6 speed. But it was too expensive. So I settled for less. It was still expensive tho. It was $10k for a 2001. But it only had 36,000 miles on it. And i also payed for a 4 year bumper to bumper coverage. Carmax was good to me :) The 4 cyl is fun. It vibrates a lot like any 4 cyl would. I test drove the 2006 V6 model. It was a very nice ride. Either way, im sure u wont be disappointed with them.
