Converting 136B (mono-injector engine with carb accessories) to 136M MPI — Parts list & knock sensor setup

Hello everyone!

I am planning to swap my current setup to full Multi-Point Injection (MPI / Simos 2P). Here is my exact situation:

Engine & Head: 1.3L engine block from a mono-injection model (136B), but all external accessories and intake/fuel setups currently installed are carburetor-based.

Block/Gearbox Prep: My setup already has the mounting location for the Crankshaft Position Sensor (CKP), as well as the factory casting boss with a hole for the Knock Sensor.

I need advice on what exact parts I need to source from an MPI donor car (or buy new) to complete this swap. Specifically regarding:

Fuel system (MPI fuel tank, 3-bar pump, pressure lines, filter).

Intake manifold with injectors, fuel rail, and throttle body.

ECU (Simos 2P), engine wiring harness, immobilizer module, and key chip.

Ignition coil pack, camshaft sensor (distributor dummy), and MPI trigger flywheel + CKP sensor.

Additional question on the Knock Sensor:

What is the proper procedure for mounting the knock sensor on a 136B block? Since my block has the factory boss with an unthreaded hole, I plan to tap M8 threads into it. What are the best practices for torque specs, surface prep, and avoiding false detonation readings?

Any guidance or potential pitfalls to watch out for would be greatly appreciated!
