thanks for all the info, i will prolly upgrade everything as a whole later. i haven't even been drifting yet with 15psi so it might be enough for awhile. i was slow for soo long that as soon as i got my 1st taste of fast i already want more. 400hp at the wheels would suite me fine hehehehehehehe. there is just something about my car, ive riddin in 300hp 240's that all they did was spin, but in my car it just squats and goes. i can floor it in 1st on 195/60/15's and my car just spins alittle then is gone.
