Might have to look in the swap thread to see if there are any engine options.
The number of cars that can have an engine swap are shockingly low, and the only race car in the list is a donor (787B's engine into the RX-7 FD). There are only 14 known engine swaps, and unless one of the 3-4 cars we've yet to see have an option (kind of doubt it)
those 14 will probably be the only ones unless PD adds more.

It would be amazing if we had more options, especially with race cars, but I think most would be satisfied with just being able to get a couple of the current engines at this point. I got one on launch day and haven't gotten one since.
Grinding for the McLaren at 10.5m which appeared today. Hope it's worth it...
I love it. Its biggest flaw is it's a gas hog in the "endurance" races we have and the downforce was nerfed in order to cram it into a group it doesn't belong. If you only plan to use it in Sport mode you can just "rent" it and avoid the price. But it's been pretty great for me, just have to work with the tune as the stock setup is a little wonky. With my driving style I needed the brake sensitivity around 45-50 and run the brakes with a -3 bias, I believe. Also played with the ride height and softened the rear to get a more balanced turn-in/exit. At work or I'd post my setup... It's an expensive car for being Gr. 3 though, no denying that, but I don't regret buying it (mainly because I'd budgeted 20mil for it so 10.5mil seemed like a steal, lol)
