Adapter plates, exhaust headers (dual port), coolant piping, will all
adapt to the ej20 just like the do to the ej22. Just a bit less
power. I had one pushing my multivan around for awhile and found it
to be just a bit lacking when put to the task of pushing the van up
hills. ej22 was better, and ej25 was GREAT. But, there is a
sacrifice as you add displacement in terms of mpg.
all the best,
Brent
