- Ported 14g turbo at 15psi
Actually I don't think you'll get anywhere near 300 HP on TBI with a 14G, maybe low 200's HP range. A 14G doesn't support enough airflow to make 300HP. The ones I've seen who have done it used modded 19C's, 18G's with TD06 or TD05H hotsides, or something bigger and non-mitsu. Starquestrescue is one of those people if I remember correctly.
