Josh- I know u said this would be a future build and what not…but seriously get a replacement stock motor…dont go crazy on boost have a lil fun…slowly build the motor yourself with the help of people here and knowledge from mike and the others…then say in two years ur motor will be complete without totally killing ur funds…also u may want to get out of the STi in a year or so…again I know u said future build do it slow and steady that way u can learn how to do it as you go and have others show u things…
