This is the PERFECT OEM Upgrade turbo for both street and track use for the EVO X

Introducing the new BL TD06H-62X Billet turbocharger for the Mitsubishi Evolution X! This is a direct bolt on replacement for your OEM TD05HA-152G6-12T turbo with no external modifications required for fitment. The BL TD06H-62X is the perfect direct replacement for the everyday enthusiast or diehard track racer wanting quick spooling powerful turbo.  

Made from forged billet aluminum, our wheel features a 6+6 blade count, slim hub, and extended tip exducer. The TD06H turbine wheel is a big step up in size from the stock TD05H. This cuts down on back pressure and allows the 4B11 engine to breathe to it's full potential. This results in a smooth powerband all the way to redline. New oil drain gasket, crush washers, and turbine inlet & outlet gaskets are included at no extra charge.

The BL TD06H-62X is capable of flowing over 700hp!

This is the PERFECT OEM Upgrade turbo for both street and track use for the EVO X

Introducing the new BL TD06SL2-20G Billet turbocharger for the Mitsubishi Evolution X! This is a direct bolt on replacement for your OEM TD05HA-152G6-12T turbo with no external modifications required for fitment. The BL TD06SL2-20G is the perfect direct replacement for the everyday enthusiast or diehard track racer wanting quick spooling powerful turbo.  

The popular 20G compressor wheel has become the go-to upgrade for the stock frame Evo 8/9 and Evo-X turbos. In stock MHI form, the 20G wheel is good but we took it a step further. We reworked the 20G compressor wheel to our specifications, providing more flow and overall power. Made from forged billet aluminum, our wheel features a 6+6 blade count, slim hub, and extended tip exducer. These are just a few of the highlights that give our Billet 20G compressor wheel an extra kick. The TD06SL2 turbine wheel is a slight step up in size from the stock TD05H. This cuts down on back pressure and allows the 4B11 engine to breathe easier. This results in a smooth powerband all the way to redline. To handle this extra power we replaced the stock TD06 thrust bearing with our 360* Monster Thrust Upgrade. New oil drain gasket, crush washers, and turbine inlet & outlet gaskets are included at no extra charge.

Now the question is, how much power does this BL TD06SL2-20G make? If you are on a stock 4B11 long block with bolt-ons, you can expect to see 400hp on pump gas with this turbo (with a proper tune). If you are running bigger cams like the GSC S2's and E85 you can expect to make up to 500hp.

2618 Billet Aluminum Compressor Wheel

Boost Lab’s turbochargers feature a 2618 billet aluminum compressor wheel, precision-milled to maximize airflow. This high-strength material is engineered for optimal performance under extreme stress, ensuring top-tier performance in high-power applications.

Assembled in Tampa, FL

All Boost Lab turbochargers are meticulously assembled in Tampa, FL, ensuring the highest level of craftsmanship and quality for every unit we produce.

VSR Balancing

As a critical step in our build process, each turbocharger undergoes precision VSR (Vibration Sorting Rig) balancing using one of our Turbo Technics VSR balancing units. This essential process controls the turbo's vibration levels, reducing noise and significantly extending bearing life. More importantly, excessive vibration places undue stress on the turbo’s bearings, potentially leading to premature failure. By reducing vibration to safe levels, VSR balancing ensures your turbocharger operates quietly and reliably, without overloading its bearings.

2618 Billet Aluminum Compressor Wheel

Boost Lab’s turbochargers feature a 2618 billet aluminum compressor wheel, precision-milled to maximize airflow. This high-strength material is engineered for optimal performance under extreme stress, ensuring top-tier performance in high-power applications.

Assembled in Tampa, FL

VSR Balancing

As a critical step in our build process, each turbocharger undergoes precision VSR (Vibration Sorting Rig) balancing using one of our Turbo Technics VSR balancing units. This essential process controls the turbo's vibration levels, reducing noise and significantly extending bearing life. More importantly, excessive vibration places undue stress on the turbo’s bearings, potentially leading to premature failure. By reducing vibration to safe levels, VSR balancing ensures your turbocharger operates quietly and reliably, without overloading its bearings.
