Engine swap
As you can hear my n20 has decided it’s had enough life. I love the wagon so much that i definitely want to keep it, but don’t want to go through all the trouble of swapping in another n20 just for the same experience. Thus an ls swap has entered my mind, has anyone done one/know of someone who has and how it went. I’m currently thinking of putting a 5.3L ls out of a 2012 Silverado, initially I just want to get it in and running with potentially doing some power and drivetrain mods later on.
Right now I’m planning on using a LOJ trans adapter, sdi ls swap engine mounts. The part that’s tripping me up is the ecm and tcm part of it, people keep saying that you should definitely go for a Holley efi while others say there’s no point if it won’t be pushing crazy power and just use a stock ecu.
The biggest worry for me is if the car will be able to handle it, from what I know the 8hp45 has a torque limit of around 332lb-ft and the ls puts out around 320-335lb-ft. Knowing that I’m still considering it because everyone ik talks about how robust the transmissions are, is that true? Do you think it will survive?
The car is a 2014 328i xdrive wagon.
