I am going to go the other route on this one. I vote go for the GT-Four parts first.
my reasoning
The GT-Four front end will add a whole new feeling and appreciation to your car. The looks you will get from other drivers, the random people asking about your car, it's a good feeling (so I have heard). It will be a whole new car to you
Wait until you have done enough research to turbo. Then when you have done enough, do more
turboing is a big investment and a huge amount of understanding is going to be needed. I am not doubting or questioning you knowledge in any way, keep that in mind. Manny is a great resource of info and the more we all learn the better. Also, if your wife is driving and something breaks, comes loose, or pops off there will be a lot of panic and worry.
all in all the choice is yours.
