What are the advantages of installing an RB25DET over an SR20DET?
The RB25 is stronger, produces more horsepower without mods, is smoother, and delivers more torque. This engine has a 2.5 L displacement, VTC (variable timing control) , 9:1 compression, and a factory ball bearing turbo. The power band on this engine is much broader. The SR20DET feels like an on off switch as compared to the linear power of the RB25. As much as we love the SR20DET, there is no comparison in torque. Lastly, the RB25DET bottom end and transmission are much better suited for high horsepower applications. Think of it as a step up from an S-15 SR20DET.
