Engine swap, game crash funny

Curious if this happens to all cars or specific.  I am at this point, if I hit triangle to swap an engine the game instantly crashes.  While playing around last night I found that I could open the engine swap screen on the Subaru WRX  but game crashed when trying the same on the other cars I have.  This is very annoying and the fact that it looks like it is hit or miss with some cars and not others makes it worse.  And this is just the newest problem I have had with this game. From chopped versions of the deluxe cars in my garage to duplicate stock performance items, the list keeps getting longer.
