Horsepower changes. The obsession doesn't.

TurboJim

From a modified 1986 Buick T-Type to today’s Mopar garage—my passion has always been performance with personality.

The nickname began with turbo Buicks. Today, my garage is home to the B5 Blue Challenger Scat Shaker and the supercharged Jeep Trackhawk. The Buick T-Type and Jeep SRT have moved on, but each one remains an important chapter in the TurboJim story.

I bought the dark-blue T-Type at 18 years old. It went through many revisions, culminating in its final mid-2000s form: a girdled 109 block, heavily massaged 8445 heads, and an extensive supporting-modification list built for approximately 600 horsepower.

It was more than a performance build. The Buick competed in IASCA and USAC stereo competitions, earned a best finish of fourth place, and reached 141 dB in the 501–1000-watt class. Eventually, changing interests led me to sell it, and having another hobby car remained a dream for years.

In 2015, I decided it was time to return—but I did not want to start another Buick build from scratch. A brand-new B5 Blue Scat Shaker, apparently ordered and then declined, was waiting at Nielsen CJDR. It was exactly what I wanted, and I drove it home that night. Today, the Challenger remains beside the Trackhawk in my current corral.
