So if one had say $2500 to spend on mods, where might the money be spent most efficiently (assuming NO juice)??? If one had an A4 it could be argued that a torque convertor would be the best first mod because while no HP is added, a reduction in times of .3 to .5 is done routinely. The same thing can be said of suspension mods in that while no HP is added a reduction in times are easily acheived with the right setup. But disrearding that, it seems to me a lid (199.00), cam (1,100.00) and headers and duals (1,200.00) would be money very well spent. At some point in time you may do ALL these things but in my opinion it is useful to see what the HP gains are costing you.
