OK, my buddy has a b17 or w/e motor from a 93GSR in his crx.. my friend says its a ls/vtec but i swear i saw b17 on the block.. anyway... last year he rolled his crx and it ended up on the roof. now i've heard that once a b-series is rolled its no more good.. can anyone help me with this? is that true? or am i going to have to swap in it another car and test it?
i may be getting a 88-91 hatch free/cheap and would love to swap this motor in since all the parts are there and its ready for that year.

if that were true, it would apply to ALL engines
