what hes simply trying to say is that u need to do alot of research. you obviously have never messedwith a car before and ur just listing prices that u found off internet sites. u can put together your own turbo kit and then have ur mechanic install it if need be. the same goes with ur engine parts. if u dont have the resources to do the job yourself, thats fine. but why not do some research on what your buying and at the very least save yourself from buying shit you dont need, like an aem ems, or sleeving your block. ib 2-3 years, there will be some many more advances in this industry, youll be wanting to sell the shit you have for the stuff that will come out.
