I can't remember the differences between the two engines, but the US S50 is a glorified M50.

Euro motor has individual TB's, Dual VANOS. I'm know there's more just off the top of my head.

Its handbuilt :)

Most of us here wont know the differences between left and right hand drive cars.

They are different motors completely. The US s50 is basically a bored and stroked m50tu. The euro s50 is a different motor.

Dual VANOS.

Only on the 3.2L motor.

many things r different between the 2...6 individual throttle bodies+plenums, greater stroke, i think round 11.25:1 compression ratio, lightweight pistons, lighter flywheel, better flowing exhaust from the header back, 96+ octane fuel required with proper tuning...which easily makes the extra 46 hp :up:

thanks, but compared to US spec motors what do the EURO spec motors go for ?

You can find a nice S50B32 for around $6-$6.5K in the US.
