Performance & Application

Built around a 76mm 48-trim compressor wheel and 56.5mm 84-trim turbine wheel, this turbo is engineered for strong, responsive power delivery while retaining the internally wastegated, compact frame layout enthusiasts already know. It’s an excellent choice for builders seeking a highly responsive 425HP-capable turbo without stepping up to a larger frame turbocharger. The T25 flanged turbine housing with GT28 5 bolt exit and choice of .64 or .86 A/R lets you tune the balance between low-end response and top-end power to match your build goals.
