bolt-ons would be more readily available for the 2.0l i´m guessing. may cost more than fabbing yourself, but a lot less time and possible screw ups. though the screw ups would be all part of a sweet learning experience IMO.
Sounds like you have a 2.0 SPI, Yes there is a turbo that will bolt on. The 83-84 EXP and GT 1.6´s. There getting hard to find.
But your motor can not take much boost in the stock form.
