Im hoping more comes out in the next few years
What is ITB, and where can we get 3.0 non stroker cams?
In all honesty this is the most passionate thread in the 128i N52 forum. Keep the debate civil, we all have valid points! The issue is definition of performance.
Has anyone actually boosted N52 to the point of failure?
I know an ARMA supercharger blew up for a e9x guy, but thats an after market super charger. So other than that case there is nothing. Therefore, the strength of n52 block cannot be argued about unless some shop takes a salvaged n52, slaps on a Garrett snail and blows it up.
Whats bad about is that n52 is fused between alu and magnesium parts so a new block would be needed to replace any such event.
I even recall a few e9x guys scratching their head over using n55 turbo on n52, because they read that n55 came derived from n52. I dont know where that thread went but my RealOEM odyssey revealed that n55 looks alot like n54 and the airbox/intke all that is on the wrong side of the engine. Anyone care to comment?
