In my opinion, one of the best updates PGG could do to this game is an engine swap update where they add existing engine swaps to more cars. Some cars in FH5 are lacking and could be more versatile and useful with more available engines. This new swaps would give players a reason to come back to these cars, and increase their usage as well as offering more alternatives to the meta.
When it comes to cars lacking swaps, two prime examples of this are the readded Lotus Esprit V8 and Rossion Q1. The Esprit’s only engine swap is a 5.2L V10, and the Q1 only gets two swaps - those being the Racing V12 and Racing 7.2L V8. The Esprit could be a much more interesting and useful car if it got swaps like the 6.2L V8 AMG (510hp), 3.0L V8 Racing from the Ariel Atom, or even the Racing V12. The Q1 is a similar story, with the car being more useful if it had swaps like the 6.2L V8 LS3 (415hp), Racing V6TT from the Hoonitruck, and Racing V6 from the Toyota T100 Baja.
With that out of the way, here is my very long list of proposed swaps to add to existing cars. I will sort them by engine and list each of them independently on different threads. If you want to vote for the 2.0L I4 - VVT engine to be added to the proposed cars, vote here. Otherwise, here are other threads for different engines:
3.2L I6
6.2L V8 LS3 (415hp)
6.2L V8 AMG (510hp)
8.4L V10
5.2L V10
