Here's What Goes Into Building A 1000bhp A90 Toyota Supra Engine

2JZ-powered Toyota GR Supras are already here. But as much as we wouldn’t want to take anything away from the incredible work done on mad engine-swapped A90s from the likes of HKS and Fat Five Racing, we’d argue that the most interesting tuning project for the new car right now involves the stock engine.

As announced a few weeks back, Papadakis Racing - responsible for mad projects like Frederic Asbo’s drift Corolla - intends to take the BMW B58 unit that powers the Supra to 1000bhp. For the first time, we can see the engine being built from the block upwards.

The standard B58 block has been retained, although it’s now full of shiny new things. There are custom-forged JE pistons, which look especially lovely thanks to special coating - the gold stuff on the top is all about heat resistance, while the black parts on the sides reduce wear on the cylinder bores.

The new pistons are mated with Chromoly Carrillo con-rods, which are joined to the standard crankshaft. The cylinder head has been heavily worked over, now featuring new valves, springs and retainers. It’s been ported, too.

Our favourite touch? That’s a tough call - it comes down to either the 3D-printed aluminium intake manifold or the red rocker cover. The latter is clad in stuff called Cerakote, which can be used on plastic parts like this.

The reason for all these changes is simple: this B58 needs to hold up to a whole load of boost from a single, massive Borg Warner turbocharger. A dyno run is happening soon, so it won’t be long before we find out if Papadakis has met its four-figure horsepower goal.
