I got a six-star engine ticket the other day, but in an ironic twist, it’s my second one in a row where I get the D1GP BRZ engine. So now I have three spare engines where isn’t at least one other model I can swap it into. At least, not yet. I do have hope we’ll see another car become compatible with each of the three spare engines I have, as I recall some engines that were in a similar situation at launch.
And for what it’s worth, I did end up putting that Escudo engine into the Lancer Evolution, since I bet it’ll control a lot better than if that engine become compatible with one (or both) of the Suzuki Swift models.
EDIT: I know speculation is generally pointless, especially for Gran Turismo, but I can’t help but to wonder if there’s a trend to which engines could go into which cars in the future? For example, the Hellcat engine seems solely be compatible with brands associated with Chrysler group, namely Dodge, Plymouth, and Jeep. Maybe it could end up going into one of the Dodge Viper models, too?
My bet is that the LS9 could go into another older GM model, like the Pontiac GTO Judge, and/or the Corvette C2.
As for my Aventador SV engine, I could see that going into another V12 Lamborghini model, so that could potentially be the Miura Prototype, the Countach LP400, or maybe even the Diablo GT. But my bet is on the other Countach.
Finally, for my LS7 from the D1GP BRZ, I’ve noticed that it goes into a “lesser” tuner model, being the older Silvia Q’s S13, which sits below the K’s S13, which is also in the game. Silvias do also seem to be especially known for drifting. Maybe it could go into the 2019 version of the A90 Supra, whereas the 2020 version could ideally be another candidate for the 2JZ.
EDIT2: I’m also definitely a fan of some of the racecar engines being compatible, especially those Group C racer engines. I’d definitely bet on the XJR-9 engine going into the F-Type, and the Sauber C9 going into the SLR McLaren. The Porsche 962 engine could go into one of the Carrera models, too, or maybe the Carrera GT.
