I have yet to see a stock Evo get in the 12s. Most of the ones I see at MIR are in the mid 13s. You have to consider launching the hell out of it to get into the 12s, most owners aren't willing to break their transmission just for a good track time.
On the spray, it should be close Guero. Good luck.
I ve drivin the piss out of one of those and I tell you they run and hook hard. Off the line they are going to pull on you, your best bet is to try to get your car to stick but it should be close. If he has a manual boost controller and bump up the boost its going to get ugly. Ive taken a couple but I run in the mid 12's on juice.
good luck man ive seen some race round my parts, they pull hard and like everyones said its gonna probally get you pretty good off the line so make it stick as much you can, spin'em too long and it might be too much to come back from
