Problems installing forced induction on an Aston Martin Vanquish

Like the title says I’m having issues installing Turbos or a Supercharger on the '12 Vanquish.

With the stock 5.9L I have the option to install twin turbos that had 140hp. I’m assuming I have installed them before because they have been purchased. When I swap engines to the 4.5L the TT option is still there as well as the option to install the Centrifugal supercharger. With the 4.5L installed I can install the turbos however at that point I have the same issue with the supercharger as I do with the Turbos on the 4.5L. On both of the situations where it won’t install, I select the item, press A and there is about a 2 second game freeze before the sound plays as if it installed however it doesn’t. I’ve tested a few other cars including the Vanquish LCE and don’t have this issue. It’s only a problem on the Vanquish.
