About The 3B swap...

[AJAEbj42]

Which is the cheapest turbo method that can be done to the 3B?

Spend some time searching the Diesel Tech portion of MUD; there are LOTS of ideas.

To go cheap, you'd need to be able to fabricate a manifold yourself and pick up a turbo at a auto recycle yard, plus all the bits and pieces. I think there was someone on MUD that put one together for around $500.

This is what I did,

The kit is around $2500 give or take taxes I can't recall exactly.
