my freind with an evo and many mods crashed his car for the second time so the insurance company is reposessing it and im taking most of his parts including ported 9 turbo, 10.5 hotside, ported & polished stock exhaust manifold, ebay 02 housing, 680 injectors, aps bov, flashed ecu, tein flex coilovers, work emotion wheels w/ stock advans, evo 7 tails
i already have tbe, intake, fmic, ebc, wideband, fuel pump, ic piping
can i use his ecu in my car even though that he had cams and im not getting them for at least 4 months

1)will my car still need to be tuned or can i just use his ecu?
2)do you guys think that it would be worth it to buy his coilovers?
3)he also has cam gears, if im getting cams would it be worth it to also get cam gears?

 

You do not need his ECU, just download the tune from his ECU and flash your ECU with it. Tein coilovers are awesome in my opinion, if you get get it for less than a grand I say do it. You don't need cam gears.
