im going to try this more than likely and was wondering does this stuff come with instructions...i plan on ordering stuff when i get the money for it but not all at the same time and put that part on and put it together piece by piece not all at once...does it matter what goes on first or last? and what type of tr6 plugs the v-power or iridium...and i have u/d pulleys will i have to sell these and get stock ones?.....also does any car come stock with 42# injectors that i can just pull out and use?....and can you use a BOV with these and what type would be best
