Guys, we're way off topic on this thread with all the N54 vs. S65 and DCT vs. 6MT garbage.
N54: Relatively inexpensive to modify, but ceiling is lower than a blown S65
S65: Expensive to modify, but far more potential than a FBO N54.
DCT: Faster
6MT: More durable (esp. at higher torque levels)
With that settled, let's get back to talking about the Gintani TT kit.
