If you’re into Porsches and tuning, then you’ll probably be familiar with the work of Japanese tuner Akira Nakai; his 911s are treated like royalty in the tuning world thanks to the wild look of that massive widebody kit.

RWB Porsches are rare beasts and seeing one being offered in an auction is certainly a great opportunity for the right person.

The bodywork of this 1989 911 Carrera 4 now features the trademark RWB fender flares all around, along with matching bumpers, side sills, a double-decker rear wing, Rotana-style extended canards and fender wings, among other, giving the German sports car a really loud presence on the road.

The suspension is now utilizing a set of KW V3 coilovers, the brakes are from a 993 Turbo and the three-piece Forgestar wheels are 18 inches in diameter and wear Pirelli Corsa tires, measuring 265/35 at the front and 335/30 at the rear. The seller also offers a second set of alloy wheels from CCW, measuring 19 inches in diameter.

This Porsche also happens to back its visual volume with some proper power, as it has a rebuilt 3.6-liter flat-six that’s also turbocharged. The single turbo kit comes from Bisimoto Engineering, while the rebuilt engine features an AEM Infinity ECU, a Garrett intercooler core, 1000cc injectors, all new gaskets, timing chain rails, belts, custom JE pistons and more. The engine produces around 400hp and 393lb-ft of torque that are sent via a five-speed manual gearbox to all four wheels.

The wild-looking 911 RWB also had its rear seats removed, making room for a color-matched roll-cage, while the factory seats were replaced with leather Momo Supercup buckets complete with racing harnesses.

This Porsche 911 RWB is currently offered in an auction over at Bring A Trailer, and it will be interesting to see what kind of offers it will attract over the next few days.
