I just got a 1jz about 2 months ago and i told myself that i wouldnt buy another bov to save some money. a month and half goes by and my friend gives me a pair of Apexi twin chambers. Now my question is that these BOV's are used and came off a nissan 300zx. now my question is that are all of the BOVs made the same way, but with differnet kits to attatch to the stock location or is it different for every car? also, if its the same BOV with differnet kits, then does anyone know where i can get the flanges and piping that is needed to get this thing working on my 1jz?
