We currently have for sale a limited edition pewter Cosworth DFX IndyCar V8 model engine, in excellent condition, supplied on it’s original mahogany base and clear Perspex dome case.

The Cosworth DFX engine was a short-stroke, turbocharged version of the iconic DFV for use in CART/IndyCar racing in the USA. First introduced in the late 1970s, it went on to dominate in CART/Indy championships, collecting over 150 race wins including 10 consecutive victories at the Indy 500.

This model was one of a limited number that were produced, and as such it is an incredibly rare and unique item of motorsport memorabilia. The attention to detail of this model is incredible and despite being over 40 years old, the model, base and Perspex case are all in excellent condition.

Dimensions:
Base diameter : 21.5 cm
Height (with Perspex case) : 17 cm
Mass : 1.6 kg

You’d be forgiven for thinking that we only sell Cosworth F1 engine memorabilia parts, we do actually design and sell brand new parts for these engines plus parts for other engines like the BD and YB.

But we are excited to announce that we’ve got for sale an incredibly rare piece of Cosworth F1 history. This is one of the experimental pistons that was designed, manufactured and tested during the development phase of the 20,000 rpm Cosworth CA engine.

It still had the Xylan-coated skirts that were used on earlier engines (the final race-spec piston was DLC coated), plus the undercrown design didn’t include the lightening holes that featured in the final design, but you can see important design features like the compound valve angle pockets in the crown and the carefully machined structural buttress ribs on the undercrown.

It led to the creation of the CA and CA2010 race engine pistons, so it’s an important step in the development of one of the most remarkable engines in F1 history.

We’ve only got one available though, so when it’s gone, it’s gone.

Did you know that when Cosworth were developing the YB engine they had to overcome numerous issues with head joint failures?

That's why they developed the WRC head gasket (on the left) and the Group A head gasket (on the right), with help from renowned sealing experts Victor Reinz.

And that's why we continue to sell both of these head gaskets today, helping to ensure that our YB customers receive the same parts that Cosworth created all those years ago.

You can find more details about both of these gaskets and order yours today from our online shop.
