Hanap ka c160 tranny - ito yung six speed. Need mo din ng 6 speed shifter. Or C56 tranny - 5 speed tranny ito pero close gear ratio at mas mataas final drive. Kung naka stage1 (Intake-Headers-Exhaust) kana, need mo ng AFC (air and fuel controller) para mamaximize yung mods mo at tuner siyempre.

Pero at the end of the day, hindi ka pa din aabot sa 4age. Pero mas malakas ka sa ibang 4afe

Mas mainam na ipon mode then change engine na lang

Or hanap ka ng complete 4age head with harness at complete sensors. Bolt on ito sa 4afe block. No need to process change engine sa car registration. Pero bihira nag bebenta nito, kadalasan buong engine talaga.

Goodluck sa proj bro.
