Replace a 215 4TEC With a 155?

[Goaterguy]

As the title says, can I replace my dead 2006 215 4tec with a 155 long block and just not install the supercharger? Will the computer play nicely with the new engine?

From what I have read it will not.

Not a straight swap. Several differences, including the computer. Might end up being cheaper to sell it and buy a 155

Same here Not a straight swap, the question i have, if you don`t change the computer would you be under or over fueling from not having boost from supercharger, also you may find someone needing a 215 computer and DESS key or where you my get the 155 motor from.

Jet pump impeller is different too

You can do what I did and change the oil pumps and end plates to the 155 and be good. that is if the oil pumps are not bad.
