hey man cool idea and im not saying this to be mean or and ass h0le. but i really dont think you can build, market and produce a turbo kit that is cost effective enough for you to make any kind of profit. companies like HKS GREdy and T1R spends mega moneys developing these kits. i see you are and avid honda tuner and u obviously know what your doing but the average consumer that is willing to spend 3 to 4 thousand dollars on turboing there car probably wants a multi million dollar name to back there kit. but what do i know good luck and i wish you the best all im saying is be care full.
