hi i have a 94 mustang and want to put a eaton m90 supercharcher on it from a cougar xr7 what kinda mods and i going to have to do to the engine or are they pretty much the same any info will help before i spent the coin and buy the cougar
In order to put an M90 on the car you are going to pretty much have to swap the entire engine. There are many small differences between a standard single port 3.8L and a M90 charged single port.
The M90 engines also have forged parts in them, so they are more desirable that way as well.
If you can get the whole Cougar for a donor car. Do it.
