Evening, engines in and running here’s a bit of a write up about it.
When I say SAIC I mean the engine from the 2012 MG6
Differences that I could notice:
Oil Filter Housing (SAIC has 1 less sensor on it, fit 75/FL1.)
Block Coolant passage with coolant sensor (it’s the same as 75 so fit FL1.)
AC Pump - Pump Mount (AC pump sits to close on the SAIC, fit the pump mount from the 75/FL1)
Crank Sensor Wing (0.5cm thicker and mounting hole in different place, cut .5 off the wing and drill and tap a new hole.)
Sump casting (SAIC has a casting on the rear of the sump that allows something to mount, this fouls the IRD majorly and will not allow the engine to mount to the gearbox properly you need to cut a 1cm off.)
Cam Sensor (completely different, fit 75/FL1 sensor it’s a direct bolt on.)
Intake (SAIC has electronic TB, fit 75 not FL1.)
Exhaust I already had a new turbo so I fitted the 75 turbo and manifold. I had to remove 2 studs to allow the 75 manifold to fit.
EGR (the SAIC has an EGR system which I completely removed and blanked, the FL1 doesn’t support EGR and I don’t see a way of incorporating it.)
Flywheel (Trigger pattern and type is different, fit FL1.)
IRD 15mm bolt ( 3 bolts on the IRD are 15mm one of these doesn’t have an thread not a major issue just don’t fit one bolt.)
Engine Mount (SAIC has the same mount as the 75, fit FL1 mount.)
The SAIC is nearly identical with very few major changes. Unfortunately I don’t know how to add images but there’s not much to the mods I did, they were all pretty simple. Most problems could be fixed if you have a doner 75 engine.
