ARMS RB26DETT M7655 / M8260 TURBINE KIT

Click on the above picture to enlarge.

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.

PART NUMBER: 173021

$2,990.00 (USD)

This is the largest size bolt-on turbo for this output characteristics at engine speeds. Reaches full boost at around 5000rpm at somewhat higher range, but from there achieves fierce acceleration with the output characteristics that almost makes you forget that it is a bolt-on turbo.

　　　　　　　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).

STOCK COMPARISON

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.

AVAILABLE IN 2 SIZE OPTIONS

The M7655 works well to suit the RB mid range characteristics, whilst still being a good performer up to the higher power band range. The M8260 however, even being a bolt on application will deliver the punch of a full peak power type of turbine kit.

100% BOLT ON

The ARMS series turbo kits all come supplied with all the required gaskets and fitting accessories for a true bolt on application out of the box. So it can be installed immediately without the need to hunt for other parts.

1 YEAR WARRANTY

The ARMS RB26 M7655/8260 Turbine Kits come with a 1 year limited warranty after the product has been registered with Tomei Powered shortly after purchase.

INTERNAL COMPONENT ANALYSIS

COMPRESSOR HOUSING	TURBINE HOUSING	BEARING HOUSING	BILLET ACTUATOR

All the housings made with different materials of metal were first closely examined and tested for energy absorption, friction, and cooling capabilities. The most ideal components were designed and utilized.			Our all new Billet Aluminum actuator is designed for added strength. This will give that extra support when needed for higher boost applications.
