The following link was forwarded to me by my brother. He's currently working on his 1990 300ZX with a goal to reach power specs in the 2005+ Mustang GT class. He's well on his way...I recently dropped off his car for him at the shop where they're going to swap his stock engine with a twin turbo. My 2005 V6 and I will have alot of catching up to do...heh. Frankly though, I'm waiting for the rumored DOD in future models before considering any modifications.

At any rate, I thought I would just share. Enjoy.
