15+ WRX Modification Minimum Recommendations
Common issues to look out for before modification
- Low Compression or Bad Leakdown
- Incorrectly gapped, old, or completely wrong spark plugs.
- Excessive carbon buildup
In general, you want to minimally have the equivalent of a fully functional stock vehicle BEFORE you start modification.
From there, here are my minimum recommendations based on approximated power goals. Each list is inclusive of the list prior.
