At CTS, we received a massive amount of requests from our customers seeking a budget-friendly-direct-bolt-on turbo upgrade for their existing IS12, IS20, or IS38 turbochargers. To meet these demands, we have designed our very own journal bearing turbocharger upgrade.
The goal was to develop a turbo with a strong power up top compared to the JB-600. Our engineers decided to keep the journal bearing CHRA from our popular IS38 turbocharger and spice it up a bit, to match the larger wheels and a performance-oriented nature of this upgrade. The thrust bearings and thrust collars were increased by 2mm to accommodate the extra load. The oil passages were increased by 0.72mm to allow the most efficient hydrodynamic wedge when the turbocharger is in operation. This turbocharger was extensively tested on our own and our partner vehicles around the world, at different altitudes and different climates.
Long story short: this turbocharger is capable of delivering approximately 650 crank hp, around 550-600whp on E85 and 460-480whp on pump 93 octane**. The turbocharger is designed for street use, while it is a bit laggy compared to our JB-600 you get the benefit of a big power up top.
We recommend to keep the boost within 29-33psi, less if you’re limited by fueling or stock engine. Do not exceed the recommended boost range, as it will reduce efficiency.
