IE450R – 5449 – Bolt-On Turbo Kit for Toyota G16E – GR Corolla / GR Yaris
Performance, redefined.
Introducing the Ichiban Engineering IE450R Turbo Kit, the ultimate bolt-on upgrade for Toyota’s G16E platform — engineered to deliver true motorsport-grade power without sacrificing OEM drivability. Designed and assembled with precision, the IE450R is the result of extensive in-house R&D, real-world testing, and performance-focused innovation.
Built around the proven Garrett G25-660 CHRA, our turbo features a custom lightweight 7+7 billet compressor wheel, developed exclusively by Ichiban to outperform standard G25 configurations. The result? Faster spool, increased efficiency, and higher power potential — without compromising throttle response or reliability.
At its core lies a dual ceramic ball bearing system, ensuring ultra-low friction, rapid transient response, and long-term durability under extreme heat and boost conditions. With proper supporting modifications, the IE450R delivers up to 450 WHP while maintaining factory-like street manners.
