All MHI Performance Turbochargers are original Made in Japan!

MHI Performance turbochargers are a high-quality result of an extremely precise production in the motor sports department of the Japanese turbocharger manufacturer Mitsubishi.

All MHI Performance turbochargers have a very wide compressor map which provides optimum performance at any speed and does not know the typical pumping. Compared to other manufacturers, MHI compressor maps have a higher efficiency over a wider range.

In addition, all Mitsubishi Performance Turbos are equipped with double hydrodynamic bearings. The exhaust wheels made of Inconel, in perfect symbiosis with compressor wheels from the latest development, convince with an amazingly early response and torque development even at low rev ranges and with low boost pressure. This means better drivability in the lower and medium speed ranges, thanks to the best power delivery in the feared turbo lag.

MHI = Made in Japan – Not Made in China!

MHI stands for Mitsubishi Heavy Industries. This is a department of the vehicle manufacturer Mitsubishi which deals among other things with the production of turbochargers for own and also foreign vehicles. MHI turbochargers are also used in the Porsche Panamera Turbo and BMW 2.0L Turbo.
The MHI turbochargers were among the first turbochargers to come onto the market as China plagiarisms. In particular the proximity to Japan and the Japanese vehicle market made these plagiarisms interesting for China. We would like to point out once again that there are still tons of MHI plagiarisms on offer. However, these have nothing to do with the high-precision manufacturing from Japan. We supply exclusively original MHI turbochargers Made in Japan!
