Frequently Asked Questions About Precision 6766 Series Turbos-935HP

What is the maximum horsepower rating for the Precision 6766?

The PT6766 CEA® is rated to support up to 935 horsepower, making it a top tier choice for street and strip vehicles needing nearly four-digit power levels.

Which engine displacements are best suited for this turbocharger?

This turbo shines on engines ranging from 2.0L to 3.5L+, such as the 2JZ, 4G63, or built EJ25s, where it can be spooled effectively to utilize its massive top-end flow.

What is the difference between the 'S' and 'H' compressor covers?

The 'S' cover has a 4.0″ inlet and 2.5″ outlet, whereas the larger 'H' cover features a 4.0″ inlet with a 3.0″ outlet to maximize airflow volume for high-boost setups.

How does the spool time of the 6766 compare to the 6266?

The 6766 will spool slightly later than the 6266 due to the larger wheels, but it offers significantly more top-end power and lower backpressure at high RPM.

Is the ball bearing version worth the upgrade over journal bearing?

Yes, the air-cooled dual ceramic ball-bearing CHRA provides faster transient response and greater durability under high boost compared to the standard journal bearing system.
