slightly faster than a stock itr even with the smaller gsr cams. these often have a short life though. one of my friends created one from a wrecked crv they had at his work. wound up running a 14.5@98mph
now on to the bad. the engine made it 3 oil changes before a rod broke
the b20 and b18b stock were never designed for 8,000+ rpm

yea deff install a block guard!!! b20s have mean cylinder walk after 5k, also if you could get your hands on a 01 b20z2 or the jdm 01 b20b they are the best ones to get. the b20b has the highest compression for b20s

hmm that's a thought if you redlined the engine at 7000 the b20 would probably live awhile and you would have a fairly quick car. even if you're down 10-15hp compared to 8000 engine life is drastically increased.

block guards are ugly creatures... Essentially you're fixing the top portion of the cylinder from expanding so the middle part of the cylinder actually flexes more and can cause damage... I'm not sure about the cylinder walk issue, but I can imagine it does because of the longer stroke.
On that note, because of the longer stroke, the rods swing side to side further than a short stroke engine... So at least get some beasty rod bolts if you're going to do it...

block guards help to prevent blown head gaskets from cylinder walk. they are what they are. as always if you want to make a high spinning motor or a lot of whp boosted you go sleeved or dart

i have b20 vtec with gsr head dont need a block guard waste of time and money doesnt do anything if your sleeves are gonna crack a block guard wont help.
look into upgrading your rod and rod bolts. either shotpeen or get some forged.
im running stock just upgraded rod bolts and i take it up to 8k all day. now i dont leave it at 8 too long and i take care of my motor. if your stuff is built right and you checked and double checked your motor should be good.
have faith in your setup and know your limits you should be okay. b20 is good but if you can go lsvtec
