Right on! What did you do for the turbo, did you have to get a bigger housing to adapt to the 4” or did you use a transition piece?

Very cool! I really want to get and NV5600 behind my 12 valve
I was checking out high impact transmission and gear, they have all kinds of kits and transmissions but are pretty spendy, I guess that is inherently a spendy piece but just the same

What are some options out there to make this work? Are the NV 5600 compatible with the first gen 6BT?
I won’t be anywhere near doing this any time soon as I just want to get the rig on the road hahaha but I do like to do my research
