OK lets see. My 2 cents on the matter.

As for my 60 times. I ran on cheap/stock Goodyear RS-As (H rated I think it doesnt have a V or a Z infront of the R) and I was cutting alot of 1.6s. If 12s are your thing Big 16G turbo is good enough and you can still do AutoX. I have a small 16g and it isnt ported or clipped. You dont need to weld the center diff for mid 12s. When you get your 60s down low enough you might want to think about it. Make sure you get and AWD with an LSD in it. These cars are not as reliable as a Honda except turbo hondas well the ones Ive seen anyways. Sorry to say that but it is true. They are not a POS either but things will go wrong time to time. You need to know how to work on a car or want to learn how because they make alot of power to move their heavy asses and they can break down spring a leak etc. But that is the fun of things knowing that you can fix your car.
