For what you get, the turbo is the better option IMHO as there is plenty of work for the swap or stroker. Unless of course, your 2.3 needs a rebuild, then the 2.5 first - turbo later?I have a 1986 190E 2.3-16V automatic and I have been thinking about 2 options:
(1) Swap the 2.3L for the 2.5L
(2) Install a Mosselman Turbo
Any thoughts on either of these?
