when i first got my gtp my wife and i went head to head her in the gtp and it was close stock for stock

03+ crowns can take the corba engines as well as the 5.4's
mines an 01 i still wanna do a 5.4 and a sts turbo swap on it

With mods they can be decent on speed cruising at 85-90 it still has a lot of peddel left
