u will need 4 cams
which might make u a lot poorer (no more karaoke for this month)
ask powerzone, matspeed for local options.
else, u can go look for rpw, piper, hks,tighe and others if u made of gold.
remember always ask the manufacturer the spec and drivability of the cam. tell them ur expectations and ask their recommendations. these are all cool guys if u ask nicely.
good luck
