Mitsubishi 6G75 SOHC 24v Mivec Performance Springs
We have finally completed research on the 6G75 SOHC 24v Mivec springs found in the Mitsubishi USA Galant 4G / Eclipse 4G vehicles and the Mitsubishi Pajero vehicles.
These are a direct drop in spring with no modifications required and will work with naturally aspirated and forced induction applications.
We are researching a double valve spring application right now with titanium retainers, but this would only be applicable for extreme modified engines only.
They can now be ordered via our online store at the following link - https://shop.rpw.com.au/product/valve-spring-kit-mitsubishi-6g75-sohc-24v-mivec/

Mitsubishi Magna / Galant 3G / Eclipse 3G Final Drive Kits - 4.670 : 1 Ratio
With the continued expansion of Mitsubishi Magna vehicles in Australia being used in both Speedway and Circuit racing events, and also within the USA, Racing Performance Works is looking to begin manufacturing final drive kits.
* Suits the Gearbox Model F5M51-1-F5N (FWD Only) 1996+
To make these we have to manufacture a minimum of 30 units, so we are looking for at least 10 confirmed orders before we can begin this.
If this is of interest then please let us know and you can place an order via the link below. Once we reach minimum numbers, we will organise deposits and manufacturer these units.
We have chosen the 4.670 : 1 ratio as the optimum size to suit all applications as well as fit directly into the gearbox without requiring any modifications for its increased diameter as per speedway rules.
If there are any questions do not hesitate to contact us and spread the word around to those that may be interested.
