I raced an RB20 and lost due to some mechanical issues. I let off after he got about a car on me. So when he started getting away that wasnt me still trying to keep up.
HKS EVCiii is not an EMS, its a boost controller, I dont even use that anymore. I have an Apexi AVC-R and a Nistune VG30DETT ecu on the RB25DET now, along with a HOLSET HX35WG turbo. Ill have another video uploaded soon of the car under its new contruction progress.
I read the whole info box. You stopped accelerating after he passed you? Rb25s have approx 40 more hp than a stock (governed) rb20det engine. You sound like a sore loser to me sir. Good game.
