When it comes to turbocharged cars, there is one massive mistake many enthusiasts make when upgrading their engine: purchasing too large of a turbocharger. Yes, an extra large turbocharger will leave you room to grow if you ever decide you need more power, but it introduces a host of other problems when compared to a stock sized turbo. The biggest problem is throttle response. The larger a turbocharger is, the higher its threshold is; this means its optimum RPM range ends up significantly higher in the RPM range. Essentially, a large turbocharger will not spool up very fast and won’t make low-end power very much. All of these things kill drivability, making your car awful on the street.
If you want excellent drivability but also want more power than the stock turbocharger can offer, a hybrid turbocharger may be the perfect solution for you. A hybrid turbocharger is mostly just the stock turbo with upgraded internals, namely a billet compressor wheel. A well-designed billet compressor wheel will weigh quite a bit less than the OEM cast wheel used in most turbochargers, and it has a larger surface area. A hybrid turbocharger typically has very similar characteristics to the stock turbocharger with extremely fast spool up, but with the added top end power of a larger turbocharger.
This hybrid turbocharger idea is exactly what Tomei is doing with their new MX-Series of turbochargers. As we mentioned above, they use a CNC billet compressor wheel. The MX-Series of turbochargers also uses a multi-rate billet waste-gate actuator for extremely fine boost control. There are MX-Series turbo kits available for RB26DETT, RB25DET, SR20DET, KA24DE, 4B11, 4G63, EJ20, EJ25, 1JZ, and G4KF. If you’ve been looking for the ultimate street setup for your turbocharged car, the MX-Series turbo is the perfect solution for you.
