Replace Stock V6 Gauge With Gt Guages? Can It Be Done?

Hi, I'm tired of my gauges in my 2000 V6 mustang pegging at 125 even though the car is still picking up speed. I would like to replace the stock gauge cluster with one out of a GT, a speedo that goes to 150. I hear from some people that it is a simple plug and play type of thing. While others tell me that you can't do it. Does anyone in here know the answer please?

Do you happen to know why the speedometer would be right but not the tach? The tach is identical to the V6 one, the Speedo is the one that is different. I'm not disagreeing with you. I'm just trying to figure out why. Any ideas?

It wont work because of the anti theft system. As far as I know.

I'm installing my saleen kit on the car this winter, so I actually think I've decided to go with the saleen cluster. I did some more research and all I have to do is take it to a ford dealership and have the computers reprogramed. Then the anti theft stuff will still work. Does that sound right to anyone else?

I believe I've heard of a couple people who have done it. They had to take it to the dealership to get it to work properly though. Dealer charged around $100 if I recall correctly.

edit: our cars aren't meant to go that fast, so there's no reason for you to do so. You won't even be able to get out of the 130s, so there really isn't any reason to get a 150mph speedometer.

Stage II Procharger, three core intercooler, 200 shot of juice, in a 4.2 stroker. Yes, it can hit 150. It's been caught on my buddy's radar. He's a baltimore city cop. As I was saying, should I stick with the GT gauges that top at 150, or just throw in the Saleen gauges, 1. because they'll match the interior and rest of the car next spring after the Saleen Kit is installed, 2. because the car does go a little higher than 150? Also, I'm not posing as a V8 or anything. I'm having special S256 emblems made up. And the honey comb panel on the back already has the V6 badge on, not the gt one.

You do realize that there are street legal twin turbo mustangs out there and that they have been winning the shootouts at dragstrips right? Research it. There was a 1996 purple TT V6 in Mustangs and fast fords last year. Ran 9.23 1/4 mile. And it was his everyday driver. If they have 4 bangers out there than can run 9's, why do people have such a hard time understanding that a 6 cyl. can too? P.S. I should note that this was originally bought as an everyday driver until I read that article. I have since bought a 94 vortec blazer 4x4 for my everyday car. I keep this as a weekend car. As for V8s, I have a 1967 Ford Ranchero with a 351w. I grew up building muscle cars and street rods with my dad. I just got the idea one day to start dumping money in the mustang. Think about it. How many beefed up GTs and cobras do you see? Now, how often do you see a V6 Mustang that could rip them a new a$$? Yes, it does seem pointless and like a lot of work when you could have just bought a V8 to begin with, but where the fun in that? What can I say? I like a challenge. Now anyway, back to the subject. So all I would have to do is take the car and the new gauge cluster to a ford deal and pay them to reprogram everything? Is that correct?

why are you getting so worked up? this is the way half of these knuckle heads think.

to make your gauges work you have to marry the two sets together. each car has certain parts that cannot leave it while a majority of the rest can. do some hard core googeling as that is the only way you will be able to get a step by step. if you cannot find it shoot me a PM i will do some searching as I have found things on it in the past before.

Yeah, +1 they don't sell a v6 speedo past 120 that I've ever seen. I'm sure there's a way to get the GT in there you'll just have to search as manzu stated... good luck and let us know what's up, I'd actually be interested, not to go over 150, but if you're still accelerating at a tapped 120, kinda wanna know the real speed? Extremely rare to go that fast but when you do a true number is nice.
