HONDA S2000 PROJECT

TODA 2.2 TURBO STROKER KIT

GReddy's S2000 turbo kit is based off of a Mitsubishi Heavy Industries (MHI) manufactured TD05H-18G turbocharger, the compact T518Z. A couple of turbine housings are offered for this turbo, 8cm2 and 10cm2. The 2.0L, F20C and 2.2L, F22C both benefit from the 10cm2 exhaust housing's larger scroll area and inlet. The larger housing makes for a negligible amount of low-end lag but makes up for it in its ability to ultimately outflow the smaller housing, something you'll appreciate once the boost is turned well past 10 psi and backpressure becomes more of an issue. Boost is controlled by a 7psi internal wastegate. This speeds up installation time and allows everything to fit within the confines of the engine bay; the longitudinally mounted F-series affords little room on the exhaust side. Like all MHI turbochargers, the GReddy-spec T518Z has one of the most durable center cartridges available, featuring a large-diameter center shaft and free-floating bushings. Such bearing designs have been shown to outlast even some of the lower end ball bearing housings not to mention most other journal bearing cartridges. The compressor wheel measures in with a 50.5mm inducer and 68mm exducer, translating into a 55.1 trim piece. The turbine's 76.87 trim comes from a 56mm inducer and 49.1mm exducer. This means that the T518Z is good for roughly 420 hp when matched with either of the F engines. Of course, upgraded internals and proper tuning will be necessary at that point.
