How much Hp?

[Streetported 1st Gen!]

Hey guys im new to this forum. And i have a couple of questions for you. I bought this 83 first gen when i was 13. Now im 15 lol. So im in the process of fixing her up getting her ready to start driving to school. Its got a 13b swap, Street Ported, High rise intake ( Aftermarket ), 650 holley, Full exhuast dont remember the name but its a good brand, Brass Clutch, And other odds and ends. How much hp should she make? Another Q. I recently blew my diff and i wanna know whats the easiest posi differential swap i can do, BOLT ON. And also if i throw a cheap turbo on her and boost like 5 psi's . How much Hp gainage would i get. Any help or advice would be great.


Thank You.
