Hello all,

I’m looking at an engine swap because my big end has gone...
I have found a 118i m sport n43b20a 141 bhp engine for sale on eBaY with the same engine code and wanted to know if this is the same as the 320i msport N43b20a 170bhp as I am after a direct engine swap or is there any differences that might cause a problem before I purchase the new lump . IE :sump, flywheel, or sensors.

many thanks all
Reece

Why eBay when there are so many engine sales in the country?

Willing to bet the OP is from America or somewhere where the use of BHP instead of KW is more prevalent.
