how much boost can a non sleeved b20z block handle?

 

people are gonna start hating on you and tell you to hit the search button. It dont matter how much boost you put, it all depends on your power range you want with a great tune....its the key to how much boost you will have. The tuner will determine how much your power are capable of....B20z capable of 200+whp easily with turbo;P

 

Think in terms of power not boost...also there is a lot of debate about the B20 and whether the sleeves are good or bad. You're probably going to get a lot of conflicting information...good luck

 

B20z, are the higher compression versions of the B20, so it is really tough to say. I've used those much more effectively on N/A cars. If you plan to replace the internals, then it won't matter, but otherwise, I would not boost the B20Z. I'd find a B20B.
