Walk thru of how to cut a 6BT manifold down to fit a 4BT. Why? My new big turbo stands tall & I wanted an option to lower it. It's not a hard process, just time consuming. Also you could cut 2 ports off one end, rather than 1 port from each end, so that you end up with an offset flange. Multiple ways to make a 6BT manifold fit your application! ~ PART#22 in a project dubbed "Nanuuq" to swap out my lifted Land Rover Discovery 2's blown 4.0L V8 & boring ZF auto for a Cummins 4BT 3.9L turbo (Holset Super HX30W) diesel 4-cylinder engine (Bosch P7100 pump) with an NV4500 5-speed manual transmission. The AWD 4x4 will remain with the LT230 transfer case divorced behind it all, & plenty of Dodge 6BT parts too. Another big phase of my custom DIY build to create a do-just-about-anything off-road / overland rig. Did I mention it's a camper too? ~ BUILD THREAD: (Entire build) https://www.overlandbound.com/forums/threads/10336/ ~ BUILD THREAD: (4BT specific) https://www.4btswaps.com/threads/100657/ ~ DISCLAIMER: Please do not do/repeat/imitate/recreate anything I do in my videos. JUST DON'T! It can be very harmful to bystanders, your person, your wallet, & your psyche. Don't risk the only "meat vehicle" you get!
