I know it's not the answer you wanted, but if you are on a budget then boosting an auto Z is going to require a significantly higher risk appetite than boosting in general (which carries its own share of risk already).

If you decide you want a boosted Z, find a cost effective way to exchange your car for a manual to boost or buy someone else's build that has a known good history (if such a thing even exists). Otherwise, it looks like a departure from the Z is in your future.
