help with turbo!!

i was wondering what type of turbo would be the best for a '93 Sentra XE with the ga16de engine. im looking to boost to around 15 psi. if there are any turbo kits that you guys know of that would help too. i would like to built the turbo system myself cuz that would be cheaper, but a kit that isnt expensive would work also. thanks
