Hey, I have a 91 MX6 GT with only a couple off mods like rebuilt engine, act clutch, manual boost controller, intake and 3 inch exhaust. Only boosting 9 psi and I got to 144 mph in 5th gear and my rpm was at 5400rpm, so I think it's possible.

My 88 GT has been one of the most reliable cars I have ever had. (I've personally owned AT LEAST 50 cars!!)

I love spanking GT mustangs and Camaro's on a regular basis.

I have done all the homework and research, along with the wrench time on this thing, and now make over 325 torque at the wheels! I can honestly say that 150mph is attainable, and can be done with much less than I have on my car.

I still don't know how these cars got overlooked in the late 80's early 90's. No Honda, or ANY front drive car I can think of can match the power and speed of the MX6 GT.

The changes to make more power are easy and fairly inexpensive -- I know because I went in small steps to get the car where it is today.

If you want a semi rare car that can beat almost any four or six cylinder on the road today -- GET A FIRST GEN MX6 GT!!!

I had a new 1989 Probe GT for 7 years in Nevada.

Sporty and fun. Good gas mileage too, about 32 MPG in 5th gear.

Top speed was hard to estimate since the speedometer only went to 120 mph. However, it had no problem handling speeds of up to 125 mph, about 1/2 way between 120 and 6 o'clock.

One night I took it on a top end run in the desert. The speedo was buried at 6 o'clock, and the engine had plenty of throttle left. But it got scary as the front end seemed to want to lift off the pavement. Best guess of the top end was 130 mph.

Negatives were viscious torque steer in 1st, 2nd, and a bit in 3rd gears, and brakes that could have been stronger. Other than that, a blast to drive.
