Would a b16 block be better for a turbo then a b20 block? Why?

 

what does "better for a turbo" mean?

 

What block would be better for a turbo motor? I have a b16 block now. But I have 84.5mm pistons for a b20 block. I wanna know which one would be more reliable to build. I'm going to send it off to have the CSS put in it. So would it matter really? Thanks

 

If you are going with stock sleeves I would recommend an 81mm block such as your B16 or a B18 with a 81.5mm pistons allowing for additional support. Of course power goals and tuning will come into play with what ever route you choice.

 

B16

Stock B16s have seen 300hp while built motors have seen 500+ horsepower

The B20 The only advantage of the B20 over the LS motor is the extra two tenths of a liter displacement. This extra displacement comes at a price however. In order to achieve 2.0 liters of displacement the cylinder sleeves are manufactured at 84mm instead of the 81mm on other B series sleeves. The design of these sleeves varies slightly from other Honda sleeves which accounts for their cracking more easily.
