We heard your demands and we are happy to unveil our latest premium hybrid turbo with a stainless steel exhaust housing specifically designed for MQB platform vehicles.\n
\nAt 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.
\n
\nThe 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.
\n
\nLong 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.
\n
\nWe 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.
\n
\nFeatures:
\n
- Perfect street turbocharger upgrade, fantastic spool and mid-range response
- Journal bearing direct-fit CHRA (compatible with all factory oil and coolant lines)
- Billet reverse rotation compressor wheel, 53.1mm inducer, 71mm-76mm exducer with extended tip (6+6 blade configuration)
- Inconel TD06SL2 reverse rotation turbine wheel, 54mm exducer, 60mm inducer (11 blade configuration)
- Stainless Steel proprietary turbine housing, made precisely for factory fitment
- VSR Balanced to OE tolerances
- Compatible with most tuning solutions for popular hybrid turbos (United Motorsport, Eurodyne, COBB)
- Compatible with OE or replacement wastegate actuators
- Compatible with OE or aftermarket turbo inlets and turbo outlets, however we recommend our 2.5" turbo outlet pipe, see below

The Perfect Sandal for Active Kids!
Size: 8 Toddler, Color: Navy
I recently purchased the Stride Rite 360 Boy's Paddy Sandal for my son, and I couldn't be happier with my decision! From the moment he slipped his feet into these sandals, I could tell we were both going to be very pleased.
Comfort & Fit: 5/5 - The Paddy Sandal has surpassed all expectations in terms of comfort and fit. The adjustable straps make it incredibly easy to get a snug, perfect fit for my son's feet, ensuring the sandals stay securely on, no matter how much running and jumping he does. The soles are cushioned just right, offering support without sacrificing flexibility, which is essential for a growing child.
Durability: 5/5 - Stride Rite has always been synonymous with quality, and these sandals are no exception. They've endured days at the park, sandy beaches, and endless pavement adventures, yet they show minimal wear and tear. The materials are top-notch, promising many more months of active use.
Ease of Use: 5/5 - For busy parents, the ease with which these sandals can be put on and taken off is a huge relief. The hook and loop closure is strong and stays in place, but it's simple enough for my son to handle on his own, fostering his independence.
Overall Experience: 5/5 - It's rare to find a shoe that ticks all the boxes for both parent and child, but the Stride Rite 360 Boy's Paddy Sandal does just that. They've been a fantastic investment in my son's summer wardrobe and overall comfort during his daily activities. I would highly recommend these sandals to any parent looking for a reliable, comfortable, and stylish option for their child. Stride Rite has outdone themselves once again!

Perfect toddler summer sandal!
Size: 6 Toddler, Color: Navy, Size: 6 Toddler, Color: Navy
My toddler loves them. Even though they are a little big for him (which I meant to buy a bigger size) the adjustable strap allows me tighten them enough so he doesn’t slide. Color goes with everything! Perfect summer shoe!
