TORQEN Nissan 350z and 370z Clutch and Flywheel Guide

When looking for a replacement clutch and flywheel package, it can often seem overwhelming if you do not know exactly what you are looking for. This article aims to make it a simpler process and aid your decision once you know all about the wide range we offer at TORQEN. 

In this article, we will explain the options for a Nissan 350z DE model which covers the RevUp as well,  the 350z HR model and 370z options, all with choices between a Single Mass Flywheel (SMF) and a Dual Mass Flywheel (DMF). 

Before we get started, it's essential to understand the main differences between the two options. The Single Mass Flywheel (SMF), while generating more flywheel chatter noise, is known for its quicker acceleration, specially on the lightened aluminium flywheel. On the other hand, the Dual Mass Flywheel (DMF) is a great choice for those using their car on a daily basis as it doesn’t produce as much chatter noise as the single mass. 

1. 350z DE 2003-2006

When working on the clutch and flywheel on the 350z HR or 370z, it's advisable to also replace the Concentric Slave Cylinder (CSC), especially since the gearbox will already be removed, providing easy access and saving on the labour cost if you need to have it replaced at a later stage. The CSC is prone to failure in these models, and replacing it concurrently can save on future labour costs and prevent potential breakdowns. This step could lead to smoother clutch operation and a more reliable driving experience. We at TORQEN recommend that when replacing the CSC, you opt for the TORQEN heavy duty CSC. 

Another alternative to this would be to use a CMAK Clutch Movement Alteration Kit. This kit deletes the internal concentric slave cylinder and moves the hydraulics outside of the transmission to make for much easier maintenance. CMAK designed this kit with all types of drivers in mind. From people wishing to daily use their 370z, to make it a much more reliable and trustworthy car, all the way to people that plan to use their 370z on a track and therefore constantly pushing the car to its limits requiring easy access to components likely to fail under load like this.

When upgrading to a clutch designed to handle a forced induction car they usually make the clutch pedal a lot stiffer and therefore more uncomfortable to drive with. This stiffness can make pulling off in first gear or reverse quite jumpy and less controlled which can be combated with an RJM clutch pedal. By using an adjustable lower engagement point on the pedal it allows for much smoother shifts and the ability to adjust it to your liking with the pedal height and angle also being adjustable for fine tuning.
