Pure Stage 2 Turbo Upgrade - BMW B58 Gen2

The Pure Stage 2 rebuilds the factory Gen 2 B58 turbo with bigger, stronger internals, so it fits where the stock unit does. It spools quickly and keeps pulling at the top of the rev range, well past where the stock turbo fades. Pure rates the Pure 800 at up to about 800 whp and the Pure 850 at up to about 850 whp.

What you get

• Billet compressor wheel and upgraded turbine wheel.
• Upgraded thrust bearing with more bearing surface area.
• CNC-ported compressor inlet elbow and a machined aero compressor bullet nose.
• Proven numbers. Pure's dyno sheet shows an A90 Supra on a stock block and transmission making 630 whp on pump gas with methanol, and 672 whp on race gas with methanol.

• Pure Turbo Model: Pure 800, or the Pure 850 for more top end.
