Another big power Z20LEH engine undergoing mapping this week, this time in a Zafira VXR making it a pretty quick 7 seater! Pushing around 430bhp from a Garrett conversion, with 3″ exhaust, Courtenay Klasen Cams, Nortech tubular manifold, Owen Developments GT28 71 HTA turbo, 630cc injectors, steel rods, Pro Alloy alloy water radiator, 356mm K Sport brakes, Quaife LSD. A very respectable figure for a hot summer’s day on the rollers.
