Toyota Aurion 50 series (GSV50R) - ECU programming just around the corner.

This may be a little premature but we have just successfully cracked the ECU from a Doner ECU and have built a file from it. The next step is to speak with my programmers to develop the tuning file and parameters, and we will then be in a position to offer reflashing services for all future customers.

We are already able to provide these same services for the Toyota Arion 40 Series (GSV40R).

With the addition of the new software we have purchased and some other developers, we are expanding the range of Toyota ECU's we can do this for.

We will be attempting to crack a Toyota Landcruiser 105 V8 Series tomorrow and the proceed with the same process. This will be especially beneficial for those doing supercharger conversions no longer needing to do aftermarket ECU or piggy back installations anymore.

As we get further developments we will let update accordingly.

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/

Thank you for your patience (Group buy people) and we hope you enjoy the new revision to the pipes for the extra increase in airflow they will now provide.

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.

Mitsubishi 4G32 Rear Wheel Drive extractors are coming back into stock.

Own an old Mitsubishi Lancer, Galant or Sigma with the ever popular 4G32 engine in both belt and chain drive (Rear wheel drive only)

We have our long tube 4-1 units made to suit both applications.

4G32/33/37 belt drive engines use what is called the round port design.

4G32/33 Chain drive engines are a little more difficult as they can come in both Round and Square port designs, with also variations in stud widths.

Now we have had stocks of the Square ports for a while now, but the round port design, is by far the more popular and we new stock is arriving in February 2026. Due to only making 10 units in this batch, we only have 5 additional units unsold.

These can both be ordered via the following weblink - feel free to ask any questions in relation to these units.

We are still focused on continuing to manafacture items for these older model vehicles and trust that the Mitsubishi community can appreciate and support us in these ventures.

Mitsubishi 4G54 MLS Head Gaskets

It appears that Ajusa may be discontinuing the 4G54 MLS head gaskets, or having supply chain issues as they are currently not available to purchase and stocks are nearly non-existant with most suppliers.

We are working now with a custom head gasket manafacture to make a batch of MLS 4G54 head gaskets, identical in design to the Ajusa units, these are being manafactured by a USA firm, these will not be chinese units.

Our initial order will only be for 10 units - but if we get a large increase in demand we are open to making more. If you are interested, or know someone who is, please let us know via this facebook post.

We will also be making these to suit larger bore sizes of up to 95mm as well for those doing big bore options, commen to the speedway market. If you need these also let us know.

All gaskets will be made in the 0.30mm thickness, but future plans will include making them in a 0.80mm MLS for those need to decompress an engine.

And yes - we know the image is of a standard gasket, not a MLS :).
