Block guard/saver???

[gettocrx]

Hey guys! I'm building a b16 motor for boost.. and planing on to put a block guard/saver. I was wondering how do these block guard stay in place. After pressed/tapped in, Does It need to be weld it in place or does it stay in place with out weldin it? I'm planing to get a nuformz or eagle one, or any suggestions?
It's a B16 with stock bore, crank , 9.1 je pistons, and eagle rods. hoping to put out at least 350+whp

dont use a blockguard. stock honda sleeves are good to around 500 whp. blockguards cause a lot more problems than they solve. if you want more than 500 whp, get real iron sleeves.

OIC! Maybe I'll just save my money and do something else with it... But why do people use these guards in the first place???
