When it came time to decide to either rebuild the factory RB25 or opt for an engine swap, this owner decided in one swift move to set the internet on fire. The owner decided to remove the inline-six and replace it with a LM7 5.3L V8. The owner was restricted to engines with 300 horsepower or less due to Sweden’s inspection rules. Otherwise it seems he would have chosen a more powerful V8 engine such as an LS6.
I am sure if there are not already a ton of forum “discussions” on this project, there soon will be. The source thread is only one day old and there is already someone disagreeing with the swap. And that is on a site dedicated to only LSx V8 motors. We of course think this is a great project. Our belief is there’s no right or wrong swap.
