Car modification after the installation of a set of HKS GT800 turbo kit, HKS camshafts and valve springs, forged engine parts, SARD fuel pressure regulator valve and 1000CC / min fuel injectors, KOYO tank, GReddy intercooler and turbo controllers, injen intake, aSpec exhaust, AEM cooling water / methanol injection system, and by COBB computer is adjusted so that the maximum power boost from 486 horsepower to 859 horsepower. HKS GT800 turbo kit includes two turbine body, intake pipe, exhaust Crossroads. Pressure relief valve. A set of modules are from HKS vw mk4 golf lowering springs to ensure that the degree of cooperation between them, this component is car GT-R core power conversion, other retrofit kits for and match with HKS turbo kit. The following diagram can clearly see HKS manufacturers logo. When a large amount of air HKS turbo pressure, intake pipe pressure will rise, if the pressure is too large, will cause damage to the intake system, and even cause damage to the turbine blades, the role of HKS relief valve is when the intake pipe the pressure inside the channel reaches a certain value, the portion mk4 golf lowering springs and shocks of the air discharged from the intake pipe pressure on the trachea road, in order to achieve the protection of the intake system and the role of the turbine.
