MSR 306awkW WRX STI Version 5 Type R
After many years of constant engineering, researching, developing and testing, I have finally achieved a new level of performance that was only possible with much more extreme levels of modifications in the past. Although it was a tedious and time consuming process, the effort was definitely worth it.
My STI Version 5 Type R produces 306awkW at 6800rpm and 798Nm of torque at 4200rpm. With more torque that punches you in the gut sooner than a Pagani Zonda can, in a rolling chassis that weighs 1300kg, the level of performance that this car is outputting from a turbocharged 4 cylinder engine that is still running a top mount intercooler is absolutely mind-boggling!
Below are the full specifications of the monster powerplant that I have built.
