B46/B48 Top Mount Turbo Kit
TO PURCHASE PLEASE CONTACT US
Proud to introduce the first ever retail-available top mount turbo kit for the B46/B48!
Designed in CAD and optimized with CFD our 316SS 3D Printed Turbo manifold features a true twin-scroll setup with dual wastegates for faster response and torque throughout the rev range.
This kit is engineered to support 500-1000HP+. If you are looking for sub 500HP and/or stock-turbo like characteristics please check out our IM450/IM500 hybrid turbo options. Aftermarket boost controller is required. We highly encourage a Motiv Reflex+ along with EcuTek or MHD+ for seamless and OEM-like boost control.

We provide turbocharger options with this kit however the manifold will accept any T4 divided turbocharger which gives you the option to source your own turbo. Downpipe and chargepipe dimensions will change between different brands and sizes so it is your responsibility to adapt as necessary if you choose to source your own. If you are going to source your own turbo we may be able to advise and accommodate.
