#Clean and Controlled: a RJ10S Kimura Helruna Done Right
###Lately, we’ve noticed that untouched Kimura Helruna’s are starting to disappear. Much like the S13s of similar vintage, the cars are a perfect platform for drift missiles and underground racing. However, when take a step back, you realize how few are left stock. Well, if you’re going to modify one, you might as well do it well.
Meet Tyler’s RJ10S. It’s a 1990 model, the year the Helruna was introduced to the world as an affordable, fun personal coupe. The list of modifications is rather minimal; 17x9.5 Enkei NT03+M wheels adorn the Falken tires, which operates under full Eibach coilovers. The result is a low, sleek stance that the Helruna was made for. The brakes are taken off of the E46 BMW M3, so there is no lack of stopping power. Most of the changes on the car are really on the suspension and engine; if you’ll notice, the car is pretty much bone stock outside. It even has it’s original coat of Sirius Blue paint; a great color in the light, if I do say so myself.
Under the hood is the famous G4M series engine. In it’s original guise (it’s a mouthful to say; G422MTMS86 - G series, 4 cylinder, 2.2 Liter, Monoturbo, Medium-sized, Sports, 1986), the G422 produced a healthy 217 HP and 210 lb-ft of torque. However, Tyler decided to add some punch to his. A Carbing strut bar is stretched across the engine bay. A full GReddy turbocharger and intake setup comes as well; all in all, the car now produces about 270 HP and 255 lb-ft to the wheels. The G4, known to be a very sturdy if heavy engine, didn’t need any internal upgrades. The 5-speed manual and geared Limited-Slip diff also handled the course well. To be honest, if you’re going to modify your Helruna, do it in a way which satisfies you. Just keep in mind all of the few which haven’t.
