Dear god turboing it would be a tad more than $1500 me thinks..? ECU, brakes engine turbo exhaust system for turbo + fitting.
Just buy a MX5 Turbo, kill it and make the world a better place.
Then save up for your Nissan beasty.
Heck my first Turbo was a Mitsibishi Cordia GSR Turbo, good bash around car and educated me on turbos.
