4bt to replace 6bt

[RGT]

can I assume correctly that a 4bt would bolt right in where a 6bt once sat? I realize exhaust and cooling hose would need to be altered, I am thinking that this might be a good swap for a first generation that has blown it's motor, any body done this?

Hopefully you can take the lead on this project and

we will all be taking notes along the way, my 4bta and 6bta projects are all i can afford to handle with family and work commitments
