Anyway I'm looking to get the car to the high 800's to 900's so wondering if I need to go a fully built motor to achieve that since when I got a quote it was around 75k to make 1500hp.

It won't last long. Previous owner of my car blew the stock motor in that range. That said, 75k to make 1500hp has to include much more than just building the motor. Get your fuel issues sorted, plumbing fixed, a solid tune, and go from there.
