Help for an Acura n00b...

What is the biggest motor in an Acura... the 3.5 liter V-6 in the RL? is there anything bigger... and if so what model\year can I find it... also cam count, and is it a 20 valve, or 24 valve... gotten no numbers on it, just that it's 3.5 liter...

also, mid-80's Integra had which motor options... and what is the largest motor that can be put into one? My friends just got ahold of one, with a blown motor... and me bieng the guy with the internet got put up on the offer to search, and I've come up with nothing so far... any websites which can better state my question is probably best... don't want to waste anybody's time donchaknow :)

anyway, thanks in advance...
