RRP Billet Aluminium Oil Sump – Rx8 Series 1 (2003-2008)
The Rx8 sumps are all looking a bit worse for wear these days and the early ones were never really that effective for controlling the oil flow around the engine pick up. This results in oil starvation when the car is used on fast road and track applications. In the extremis this will cause catastrophic engine failure and at the very least greater wear to the front and rear Rotor and Stationary bearings reducing the life of your engine.
The RRP sump is designed to combat Oil starvation using a unique “Bathtub” design limiting the oils fore and aft movement while naturally providing more oil around the engine pick up, this combined with the internal walls which combat lateral movement and a separate Baffle Plate stops oil starvation while also completely stopping what is known as oil burps.
Machined from one piece of 6061 Aluminium and Anodised in Anthracite for corrosion protection this sump will outlast the lifetime of the car. The OEM level sensor is retained, simply removed from the original sump and refit to the RRP sump with no loss of functionality.
- 3.23L Capacity. (OEM c3.75L)
- Oil channelling to stop oil starvation.
- Contoured Bathtub design, the only sump on the market to have this feature which aids in keeping oil around the pick up as well as more effective draining due to the relocated drain plug which is at the centre of the “Bathtub”.
- Cooling fins which increase the effectiveness of the oil cooling system.
- Separate 3mm Aluminium Baffle plate.
- Two oil ports which could be used as Turbo returns and/or Gauge Sender ports – AN8 ORB 3/4 16 UNF

Excellent oil sump, dear friends, you showed us how to do another masterpiece. Great quality and stiffness, it was a pleasure for my mechanic, myself and my beloved RX8. Good job, Carl!!
You’re most welcome Aldo. Glad you like it.
Was blown away by the quality of the sump, everything is there that’s needed to fit. Communication ahead of purchase was also excellent, given I was one of the first to receive it. It could have been twice the price and I’d have still been impressed by the quality and fit! A little fiddly to install the sump onto the baffle plate but that’s just the way it is and can’t be helped. Overall it’s 10/10 for me. Many thanks for another excellent RRP product.
Excellent news Adam, we're so glad you like the sump. Stay safe Adam and happy motoring.
