A 964 Turbo Built for Japan's Wildest Racing Series

The 964 Turbo was Porsche's last air-cooled forced-induction effort before the 993 refined everything. In period, these cars were weapons—3.3 liters of boost-fed flat-six sending 320 horsepower through a G50 gearbox to rear tires that were constantly auditioning for a ditch. Factory, they were already serious. Converted to JGTC GT500 spec in 1994, this one became something else entirely.

What you're looking at is a freshly primered shell sitting in what appears to be a Nevada shop, stripped down to its chromoly skeleton. The cage work is proper—lightening holes drilled through the door bars, triangulated rear section, all painted to match. That front trunk shows the 993-based 3.8L RSR block waiting for its moment, though the intake situation needs sorting (the six-throttle Mode Motorsport manifold has a bolt pattern mismatch). The RAYS magnesium center-locks—10-inch fronts, 13.5-inch rears—are sitting ready. All the bones are here: G52 five-speed with LSD, JIC Magic coilovers, spherical bearings throughout. It's a parts explosion organized by someone who knew what they were doing, then apparently got distracted for three decades.

This is emphatically not a car for someone who wants to drive home on Sunday. The twin-turbo conversion exists only in theory. There's no intercooler. The fuel cell needs work. But for a builder who understands what a legitimate JGTC-spec 964 shell represents—and can source the remaining fabrication—this is the kind of project that doesn't surface often. The original Wangan history and magazine features add provenance, though you'll need to verify that documentation exists in more than just the listing notes.
