Porsche Type 901/16 — 2.0L Flat-Six Engine (1969 911T) — Numbers & Performance Core

Porsche Type 901/16 Engine — 1969 911T 2.0L Magnesium Case, 2040cc, JE Pistons (☆6196078☆)

Rare, robust Porsche Type 901/16 2.0-liter flat-six built for a 1969 911T, offered as a complete engine core with important performance upgrades and professional machining already carried out. The magnesium case and historic stamp ☆6196078☆ confirm period authenticity. Machine work was performed by Ollie’s Engineering (Lake Havasu City, AZ) — the case was line-bored and machined for standard main bearings. The top and bottom end have been upgraded to a 2,040cc specification using Biral cylinders and forged 81.0 mm JE pistons, yielding a 9.8:1 compression ratio for stronger, more responsive performance while retaining vintage character.

This engine is an excellent foundation for a concours-correct or sympathetic performance rebuild for 1969 911T restorations, resto-mods, or high-quality replacement cores.
