i got this turbo for free..jw what it is. i saw a sticker on a piece of it..the 'unkown piece' that said chrystler on it. will this work if i wan to boost my ls motor? also how many pounds do u think its set at internally? 1 more thing..how do i tell if there play. i was trying ot spin the thing inside and it took a little bit of effort to get it ot move, and didnt move side to side but moved maybe half a millimeter in and out. should it be ok to use. and will that exaust section work???
