Bisimoto Engineering has become known in the industry for its crazy creations, and this is perhaps their most iconic demo car: a Porsche 911 with an exposed pair of turbos sitting proudly on display.
Bisimoto’s first-ever 911 produces 850 HP on 18 psi of boost courtesy of a water-cooled flat-six sourced from a 996-gen model that’s paired to a manual transmission from a 997. The modern tech doesn’t stop here, as the 1976 “Iroc 930” also features drive-by-wire throttle and a full CAN bus system.
Perhaps the most noticeable part of the build is how Bisimoto has tuned the turbos, gradually increasing the boost pressure with each gear to improve driveability.
Of course this is still a Porsche 930 with 850 HP, with its lightweight 1970s bodyshell strapped to one hell of a powertrain, hissing and growling with every throttle input. However, thanks to the clever work tuning of those turbos, it does so without making the driver feel like they’re holding on for dear life, at least according to Jay Leno who got a complete tour inside and out by the company’s founder.
Bisimoto’s take on the older 911s is much different to what we’ve been treated to over the last couple of years, as they are modernizing a classic 911 and adding tons of power. The fact that it looks so cool with its turbos hanging out of the back and that it’s not an undriveable monster is a testament to their work.
