t5 trans swap?

Im looking for the most economical swap that will withstand 650 h.p and give me and o.d that wont grenade easily. I dont want a huge transmission tunnel either,it just looks terrible. An A 518 wound be o.k,it doesnt make too huge of a floor hump but apparently the o.d units arent very strong and dont last.

So now Im looking at manual trans,with a 5 or 6 speed being the most desireable.

An 833 o.d with passon hemi gears o.d set would run better than 2 grand,but so far it's actually looking economical compared to some of these other trans

A viper trans is a huge floor hump,me no likey.Im assuming the same trans from any car would be the same size.
