| ok someone posted in search saying.. AMZ stage 2 is about Z1 stage 1.. around the same price... i would chose either one of these.. AMZ is closer to home.. and seems like they could use the business.. Z1 is.. a gift from GOD when it comes to 300zxs.. sport 500.. not sure.. it seems these turbos outdo the standard sport500 design.. because they use sport 500 as a comparison model..or standard.. does anyone have any information on AMZ Stage 2 or Z1 Stage 1 the quality, reliability, response/lag, overall power? im purchasing a set by tonight.. no holding back..
