after market turbo's
 

i have a mk3 gls and i'm looking into making it quicker, and i am doing an wheels and tires right now, and i'm gonna do an exhaust but i would like to also instal a turbo at the same time just so i'm not paying for part's like headers twice, so i'm not looking for anything with a huge amount of boost preferably i the 8 psi range so i don't have to do a turbo timer, i would like to have it proucing boost all the time, with out paying a huge penalty. so heres my question what is available within the jetta comunity as far as after market turbo's normaly i work with lotus's and i just don't have the time to do that much research.(by the way i'm a highschool student so i do have a tight budget). thx
