Dude, trust me. Go with suspension first, and then worry about going fast. A nasty suspension setup will make you feel ,uch better than the generic B-series swap.

I'm sure the speed will get your attention for the first month, but as soon as you try to take a turn, your going to wish you would have spent that money on some 36-way adjustable coilovers and strut/sway bars with a nice set of stickies.
