The TTE475 IS38 upgrade turbocharger is a further development of the popular TTE470, specifically for the VAG EA888.3 2.0 TSI / 1.8 TSI MQB engines. This hybrid turbocharger retains the original IHI turbine, but with modified blades for increased flow and lower EGTs. Combined with a billet 6+6 blade compressor wheel, the TTE475 delivers up to 475 hp with an OEM-like spool and rapid response.
Thanks to the reinforced TTE bearing package and CNC-machined silencer delete, reliability, efficiency, and noise are improved. Plug-and-play installation makes the TTE475 a direct replacement for the original IS38 – ideal for those seeking maximum performance with an OEM fit.
