Visit Preferences to set your user name Summary of change: '''Overview''' 2.6 litre ADV I5 in my VW Microbus Syncro ceased due to oil starvation. I am now rebuilding a second hand AFU (2.3l 10V) and want a modern ECU with knock sensors and lambda control, hence this project site. * Engine: Audi (VW SA) AFU 2.3 litre I5 with Motronic 1.5.4 ECU. * Goal of rebuild: I want to re-build the engine with low-end torque in mind and max power around 4500 - 5000 rpm. Normal cruising speed at around 4000 rpm. . ---- '''Engine Build''' * Block (measurements) * Crank (measurements) * Pistons (measurements) * Conrods (measurements) * Oil Pump * Head (measurements) ** Porting or not? ** Port matching opinions? ** Camshaft timing for torque @ ~3000 rpm ** Inlet Manifold options?
