Is it possible to engine swap a 316i to a 318i?

18 May 2017

Long story short, my engine died. It’s an M43TUB19 with 105hp. Can I put an M43B19 with 118hp without changing anything?

Swap it to a 6cyl

I can’t… Too expensive to be legal here in Portugal

I think you need to swap the ignition when you swap the engine

Why not buying the 6cyl right away or the next bigger engine respectively

I have a 316i. I will put the 318i engine because it’s the same price and since the engines are very similar, I don’t have e to pay taxes. Here in Portugal you pay a lot if you wanna change the engine… Just to give you an idea, my car costs 2400€. The price for the engine that I want with installation is 600€. If I wanted a 6 cylinder I need 1000€ plus taxes to make the car road legal…

except for the ECU yes
but its good to put some new stuff
ex: ingition filters fuel….etc

É mesmo preciso a ECU?

Don’t swap a M43TU for a M43. The 13HP is not worth it.

I know it’s not. But I don’t want to get a bigger engine. I wanted the same but it’s difficult to find. So I was just wondering if it will work. I don’t care if it has more or same hp. Just wanna know if I don’t need to change anything
