Hello!

I am considering swapping out the gas engine on an '84 westfalia. Does anyone have input as to the best candidates to be swapped in? I have been looking into the Nissan SD22 or SD25, and also wondering whether a Jetta TDI engine would work, and if so, which years/styles are most appropriate. Any other ideas? Mainly I'm just looking to swap to diesel. I would also appreciate input on what other things I'm going to have to consider in the swap.

Thanks!
