RB26DETT Tomei Turbine Kit

All New Design, Maximum Grade 　Bolt-on 580PS M7655, & 650PS M8260 Turbos

After 22 years of the RB26 first debut. The impression left has lead many people are still enjoying tuning. At TOMEI, we wanted to see more users enjoy tuning their engines, so we continued development on new products. During the development process, with such diverse testing of housings, turbine wheels, and actuators was completed both on the engine bench Dyno and on actual use on a vehicle. The usual surging that is common with twin Turbos was suppressed. The right turbo design was made that will spool all the way up to high rpm as intended for the RB26 was completed. Up until now, when aiming for higher output power of more than 600ps, larger modifications were needed to the exhaust manifold for an additional waste gate, which also increased costs. But now, this turbo kit is compatible with the stock exhaust manifold, and it is a 100% true bolt-on application that can potentially deliver more than 650ps (M8260).

• SURGE CONTROL

When driving the car on the street, at times the stock turbo can produce unpleasant surging at higher speeds. We have designed our Turbos specifically for the application to resolve this matter.

• MAINTAINING POWER AT HIGHER TUNING

With the stock displacement, you can expect to see good power from 6500rpm and higher. But with the increase in the engines displacement, even more potential gains are possible.
