Acura RSX with a 1000+ hp Turbo K-Series
In 2021 Javier Trias and his team at That Racing Channel set out to create the ultimate AWD Honda. Two years later the company drove their Acura RSX down the quarter-mile in 8.516 sec at 163.73 mph.
At the heart of the project is a turbocharged 2.2 L Honda K-series inline-four built by Jay Meagher at Real Street Performance. The motor starts with a copper o-ring K24 block and Darton MID sleeves. In that Jay installed a Brian Crower destroker kit featuring a 4340 billet crankshaft with 92 mm stroke and B18A rod journals, MOAR design rods, and custom JE pistons. On top sits a K20 head with Drag Cartel 3.2 Ultimate Street camshafts.
Boost is generated by a Precision 6875 Gen 2 turbocharger paired with a KLM Race exhaust manifold and intercooler, and Turbosmart BOV and 60 mm wastegate. The fuel system starts with a Fuel Safe cell and Aeromotive 1400 hp capable pump supplying eight injectors; four ID2600 injectors and four ID1700 injectors. A Motec M130 standalone ECU maintains order. The motor has six boost levels ranging from the lowest 15 psi making 500+ hp to the highest 40+ psi making 1000+ hp.
The AWD conversion begins with a Competition triple-disc clutch and Momentum Motorsports Quaife QKE8J five-speed sequential transmission with a Drag Cartel billet housing. From there power is sent by a Drag Cartel billet transfer case through a custom driveshaft to a rebuilt Honda Wagon rear differential supported by a Hub City diff mount kit. Driveshaft Shop axles are used in front and rear.
The RSX’s suspension features spherical lower control arms and D3 adjustable coilovers. It was also converted to electric power steering. The car cruises the streets with a set of Enkei RPF1 17-inch wheels with Toyo tires. On the drag strip it switches to Rota Slipstream 15-inch wheels with M&H Drag radial 255/45 tires.
On the inside they installed a Haltech IC-7 digital dash behind a Nardi steering wheel. Beside the Braum Racing Falcon seat is the Quaife sequential shifter.
All the car’s progress was condensed into a 25-minute video below.
