Mike, I hear ya.. I think if you want high HP drag/street car then I would highly consider Supra. Don't get me wrong, I love FDs but like yourself, I've seem so many of them go down on the drag strip and so many Supras make it down the drag strip without issues.
If you were to build a road course/track car, I would say stick with FD but high HP drag, I say go with the Supra. I would!!! I say just put your FD back to twin and enjoy driving down the road... and have a Supra for Drag events... Dang, I want a Supra now
