I’ve been thinking about this and I reckon classifying engine swaps can be done.
Something like this.
Universal Engine Swaps: Engines which are very common and almost every car will have 1 or more of these, like the 1.6 Turbo Rally, 6.2 V8’s etc.
Manufacturer Exclusive Swaps: Cars within a brand will get these engines and you can be creative here, like the Ford Ranger’s turbo diesel 4 cylinder being swapped into the Fiesta ST or the Focus RS’s 2.3 Turbo being swapped in to the Foxbody Mustang.
‘But Vic’ you might say, ‘What about manufacturers with only one car?’ Surely they can’t be left with just Universal engine swaps? 🤔
You’re right, which is where the next group comes in.
Bespoke Engine Swaps: This’ll be tricky to balance, But it’ll make every car feel more unique as every car will get at least 1 engine swap that is unique to that car and here the only limit is if it can fit in the car.
For Example, swapping the Morgan 3 Wheelers engine into the BMW Isetta or Honda’s rev happy F20C being dropped into the AE86.
Yes you could get daft and sacrilegious with this option and you can argue it’s kinda already being done to an extent, but this way every car will be worth picking up and maybe create a new Meta car in the process.
