CTS Turbo JB-600 Turbocharger for VW Audi MQB

CTS Turbo's JB-600 is a premium journal-bearing hybrid turbo with a stainless steel exhaust housing, built specifically for MQB vehicles as a budget-friendly direct-bolt-on upgrade over a factory IS12, IS20 or IS38.

Built for fast spool and torque

The goal was a drop-in turbo with fast spool, a massive torque curve and reliable performance. CTS kept the journal-bearing CHRA from the popular IS38 and reworked it for larger wheels: thrust bearings and thrust collars increased by 2mm for the extra load, and oil passages opened up by 0.72mm for the most efficient hydrodynamic wedge in operation. Tested worldwide across altitudes and climates, it delivers roughly 600 crank hp, around 520-530whp on E85 and 430-460whp on pump 93 octane. It is built for the street with a focus on fast spool and solid mid-range. Keep boost within 25-28psi (less if limited by fueling or a stock engine) and do not exceed that range, as efficiency drops.
