acid pro's probably the easiest to use for that, you'd just have to chop it in certain places to get it to sit on beat

I would render your track to a wave file and open them both in a multitrack editor (Like Adobe Audition/Cool Edit Pro) and there you can chop it up in a non destructive way and timestretch/pitch it till it fits

Try to establish the BPM of the vocal track, in some tools like Sound Forge you can enter the original and desired BPM and it will pitch it accordingly. You can also calculate it easily. Say the vocals are at 130BPM and your track is at 167BPM. If you do 167 / 130 you get 1,2846 which means you have to pitch it up 28.46%.

another good thing to mention, is that you don't have to change pitch of your sample, you can just use time stretch and then you have the same pitched voice but matching your bpm

Oh yeah that's what I meant, simply pitching it doesn't help much ofcourse

opening it up in acid isn't gonna harm the original file

Also try to cut your accapella in a few smaller parts and then mix em to the beats.
Because the time stretch algorithm isn't perfect (I assume), at certain points the accapella will sound off-beat if u use an accapella of let's say 4 minutes.
At least that's what happened when I tried it...
On the other hand I used Cool Edit, don't know if it's the same in Acid.

Try to get it more or less to the same speed with a time stretcher and then chop up in sentences.

The more chops you make the more control you have. Take care that the chops are not audible and that it doesn't harm the flow of the rhymes.
To save time you can just chop every time you notice it starts deviating from the rhythm.
Easiest is to play only a few sounds (eg kick and hihat) while making the edits and placing the individual chops.
Also don't overdo it, you can eg chop every syllable and quantize them perfectly on the beat but then it starts sounding robotic, small mistakes are essential for the human feeling 
Just experiment!! You'll get the hang of it in no time.

I mostly cut out a certain # of bars that can be easely fitted into the structure of the track i want to put it in (mostly 16 or 32 bars of an accapella).
Then just load em into FL and let it fit into 16 or 32 or whatever...
Sometimes this isnt enough (u could've cut the sample a bit too long or short), and u'll have to use the pitch, pitch it till u reach the sound of what the autodetect gave, and then pitch up or down to get it right...

true, what app u using? FL has a great time streching feature i use frequently, i wouldnt advise pitchin the voc unless necersary it can damage a track, although on heartbreaker i pitched the vocals up there and it went nicely

Cutting up and time-stretching is the way, spend some time and you'll get rid of the 'gaps', also reverb and delay will help smooth the vocal out depending on how you want it to sound.

It depends on what the source material is. If its vocals from a "real band" track, youre gonna have trouble syncining it up because the chances of live musicians staying exactly on the beat is miniscual. If its got a sequenced beat then you wont have the timing issues, but unless you get the speed exact the vocals will gradually drift out of time.
I think the easiest thing to do is to chop the sample up into 8 bar snippets and work with those one at a time. That way even if the BPM doesnt match exactly, it wont have long enough to drift out and you wont have to go through all the hastle of automating tempo changes for the whole vocal track. Plus if its a ragga vocal then altering the pitch wont be wholey noticable.
