To be honest since I've put it on The car hasn't seen much action when I got it from my buddy it had 2000 in it and I've maybe put 1000 on it tops. I only run 10 Boost controller hasnt worked lately and have been to busy to fix it. I drive conservatively with gas prices the way they are. I'll throw in the 650s if you want because if I go bigger I'm going to want to get a little bigger injectors. Still have the balance shafts but when I'm rebuilding I'm taking them out. I can send you the evo 3 manifold too If your interested!! trying t to make it a fair trade. I'll take it off tonight and take pics for ya. Like I said before I'll throw in the j pipe as well with is like 80 bucks on slowboy I bought it with the sbr front mount kit and I obviously won't need it. I'll try to put pics up asap I have to go to work till about 8 and i've been putting a new engine in a friend wrx so havent had much time.
