1991 Dodge Stealth RTT Twin Turbo 3.0 turbo


High performance car with big problem after years of ownership


Catalytic converters melted at 60,000 miles.

Active exhaust system does not work.

No sufficient power and at no time pressure (turbo) gauge indicates full boost.

General Comments:

Good high performance car with no problems for years.

Help: After replacing the catalytic converters the car lost extremely power. The pressure gauge indicates most of the time not more than half boost (7).

I don't know the reason, but I hope somebody is able to help!

Would you buy another car from this manufacturer? Don't Know

Take the guts out of the converter. They're not built for racing and they melt. Keep the actual converter on so you pass inspection tests and all just take the guts out.

This is all you need to know. I have owned 2 for 8 years. Both TT. There are easy fixes. Your boost solenoid might need replacing. Easy. Join our forum, many mechanics on site. I am blusilvr on that board, look me up. What year/color do you have?

I have a 91 Twin turbo that has an ecu engine computer failure. I have seen replacements as high as $1,200.00. Does anyone have a less expensive alternative. How difficult is it to replace the defrost vents near the wind shield. My email is gshackett1@aol.com Thank you. I wold love to get this car back on the road. Best car I've ever owned. Had it since 1991.
