Hello guys,

I have a very big doubt. How mutch power can handle stock sleeves?
I'v seen A LOT of people on internet saying that his car made 300-350-400-450 and even 500whp with stock sleeves.
In evans-tuning parts-chart it say that stock sleeves can handle up to 400whp.
But here in my circle of acquaintances there were 4 b16 with cracked sleeves, 2 of then with just 280whp, another one with 330whp and another with 420whp. Other people in my country experienced cracks with 300whp+

I am now with [email protected], and very afraid to boost it up.
So... is there any secret? or it is just matter of LIFE-TIME?

There is no set in stone as to what the limits of stock sleeves are but if the engine is suffering from detonation under load it's only a matter of time before something gives. We pushed 411bhp on a stock b18c4 recently, so far it's holding up well.
