Earlier this month we showed a 1,000hp bolt-on kit for the Porsche 911 Turbo from America’s Switzer Performance Innovations (SPI), but the man behind the Ohio-based tuning shop is determined to show that his company is no one-trick pony. SPI also has a milder performance upgrade for Tiptronic-equipped Porsche 911s, but with 0-60mph times of 2.5 seconds there is certainly nothing tame about this latest kit.

The new kit is the L4 700/750 Tiptronic package, which SPI’s Tym Switzer explains was developed to appeal to a much broader audience. “The L4 700/750 was designed to be flexible enough for everyday driving without compromises, and our customers are always telling me how easy the car is to drive,” he said.

Starting with a standard 997 Porsche 911 Turbo, SPI adds its own custom DME software, a pair of uprated variable-turbine-geometry V3 turbochargers, new intercoolers, and a race-style full exhaust system. The end result is a 0-60mph time of 2.5 seconds, quarter-mile runs in the mid-to-high 10 second bracket, and a top speed in excess of 200mph.

How much for all this goodness? SPI charges $18,450 for the basic kit with installation handled at the tuner’s workshop in Oberlin, Ohio.
