Well I was only wanting to make about a hundred horsepower anyway. The motor sits at right around 65 hp stock, and I'd be perfectly happy with a hundred hp. It's bot like I'm gonna be street racing or anything. But as far as transmissions, they don't give torque, what your talking about is gearing. And Im planning on getting a 4speed with dual range out if a brat. And the turbo wouldn't be extremely difficult, it would be low boost, the ea71 has a 8.5 to 1 compression ratio which is perfect for low boost applications.
Now as far as suspension mods, I can't find squat, I'd like about a 1.5 inch on the back and 2 in the front since the back sits slightly higher, but I've been very unsuccessful in finding any suspension upgrades. Do they brats have the same suspension as my dl? Seeing as how my car is basicly a brat with a roof. Haha.
