TTE | SW10065-01

The TTE800 is a high-performance turbo upgrade from TheTurboEngineers, developed for the Porsche 993 Bi-Turbo. Based on the original BorgWarner K24 turbos, it has been completely redesigned internally to deliver over 800 hp with a perfect balance of raw power, responsiveness, and reliability.

At the heart of the TTE800 is a newly designed billet compressor wheel with a 54.5 mm inlet, chosen for its exceptional efficiency and high airflow. The compressor housing is CNC-machined and re-profiled to optimize airflow and minimize losses. A larger, lightweight 9-blade high-flow turbine is integrated on the exhaust side, delivering increased flow, lower exhaust gas temperatures, and reduced backpressure.

For maximum reliability, the TTE800 is equipped with a reinforced 360° high-performance motorsport bearing, designed to withstand sustained loads at high boost pressures without sacrificing responsiveness. The original BorgWarner spring-loaded actuator (standard 0.8 bar, optional 1.0 bar) is retained, ensuring the upgrade maintains its OEM fit and reliability. Each turbocharger is individually high-speed balanced up to 250,000 rpm and comes with an official balancing report.
