where do i sit, i have a euro motor in a US e36 shell lol.

suppressor13,please do your homework before you post, the euro s50b30 cooling ports are bigger then a US s50b30,the euro head flows much better,the euro has larger outlet ports etc.....

the us E36 m3 engine is a bored/stroked version of the euro 328 engine code S41 the euro m3 3.0 has a s50 so does the 3,2 series!!!!

That's what I said... Wikipedia's explanation is a little weak but useful. Nonetheless, the S50US is a Motorsport engine.

And US Detuned ///M3 E36 Engine code is S52 same as Euro just 46 hp less I meant to say: wikipedia.com there is explanation of difference between US and Euro M3 E36!

Dumba$$ get education first go to wkipedia.com ,US ///M3 E36 has a detuned engine that looks different that Euro and only 46HP less from Euro 286HP excluding EVO //M3 engine 321HP only imported by special order in US! Your facts is as good as nothing!!!Knowledge matters go get some!!!!!!

Hmmm. Most of you lack facts when you speak. The biggest difference between the Euro S50 and the S50BUS is the use of the plastic intake similar to the one found on the M50(325is) engine. All you need is a set of individual throttle bodies, solid lifters, and the euro VANOS and its the same engine. Regardless, the S50 is a waste of money. Stone age technology, no torque, it's huge, and it weighs a ton. That's why the RB26 and the M50 are being replaced by a V6 and V8, respectively. Inline 6 is what you find in a WWI biplane.

ya first is a e36 325

yes ı do buddy

E36 M3 3.0 286hp us-46hp E46 M3 3.2 343hp us model-10hp
E36 M3 3.0 evo 296hp us-56 E46 M3 cls 360hp
E36 M3 3.2 321hp us-81hp

Your English is fine, but your don't seem to have any evidence to support your claim. Externally it can look very similar, but the biggest difference is the Displacement, Compression, and Intake...
