Second, what is different? Is the Si stonger? Are each of the gears (1st, 2nd, and R) going to all have different ratios?
Thanks for any advise you can give.

transmission will bolt right up and use your existing axles
the only difference in the DX and Si transmissions is the differential Final Drive - DX is 3.888:1 - Si is 4.25:1 - gears 1 thru 5 are the same - what this means is that the Si is geared lower in every gear because you multiply the individual gear ratio by the final drive ratio
