08-14 STi Modification Minimum Recommendations

Common issues to look out for before modification

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.

Stock Turbo Level (VF ~300whp max)

Mild Turbo Upgrade Level (18G, or similar ~350whp max)

Moderate Turbo Upgrade Level (20G, Dom 1.5 or similar ~400whp max)

Reasonable but not required upgrades

For power levels in excess of these I recommend direct consultation in order to help you tailor a setup to your needs. Upgrade paths can diverge depending on specific requirements.
