T3/T4 TO4E Hybrid Turbocharger .63 A/R 73 Trim 400+ HP
The T3/T4 hybrid is the most popular universal performance turbo ever made: a T3 turbine section for quick spool mated to a TO4E 73-trim compressor for 400+ HP airflow. The .63 A/R turbine housing balances response and top-end for street builds. T3 inlet flange fits the huge ecosystem of T3 manifolds — Mustang, Civic, Miata, 240SX, rotaries, and countless custom builds. Oil-cooled journal bearing, 5-bolt downpipe discharge. Built new, dynamically balanced. We supply performance shops and distributors.

T3/T4 .63 A/R: The Universal 400 HP Street Turbo
The T3/T4 hybrid earned its reputation by doing one thing well: bolting a bigger compressor onto the quick-spooling T3 turbine everyone already has a manifold for. The 73-trim TO4E wheel supports 400+ HP on gasoline, and the .63 A/R housing keeps spool street-friendly.
Universal turbo lineup
| Turbo | Best for |
|---|---|
| T3/T4 TO4E .63 (this page) | Gasoline street builds, 400+ HP, T3 manifolds |
| HX40W Super Drag + T4→T3 adapter | Diesel street/strip, higher airflow |
Installation
- T3 inlet flange — fits standard T3 manifolds. 5-bolt downpipe.
- Journal bearing: run an oil restrictor per your feed pressure; ensure a straight gravity drain.
- Prime before startup. Set boost control before hard pulls — the 73-trim flows fast.
