One of my buddies wants to build this setup and then boost it. What do u guys think. What kind of horsepower/torque would u expect this setup to put out stock? Thanks.

 

tell him to sleeve the block and run a crazy amount of boost. b20's cylinder walls are a lot thinner than that of a b18 because of the increased bore size, and they aren't really designed to rev past 7-8k like a vtec b series. if built right it can be a very powerful and reliable engine, but take any short cuts and your screwed.

 

ah the cyl walls are only 3mm thinner but I do not suggest reving it high unless you plan on having a blown motor.
