ARMS MX7655 Twin Turbo Kit (Journal Bearing), R32-R34

After 22 years of the RB26 first debut. The impression left has lead many people are still enjoying tuning. At TOMEI, they wanted to see more users enjoy tuning their engines, so they 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 Nissan 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.

Without losing mid range speed transient characteristics, the boost will reach the 4500rpm range with ease. Even from there, it can suddenly spool up to higher rpm range without losing boost. Delivers vicious acceleration that is what RB26 owners want to have.
