I am currently running the Si gearbox on my 2.0 silvertop in my mk3.5.
I am breaking my escort estate so was going to fit the ib5 box from that as it's a rear starter which will help out with my manifold issues.

1)Will the ib5 box fit?It looks like it will fit but want to double check.
2)Will the lsd from a S2 fit the ib5?I am sure I have seen somewhere that it does.
3)What release bearing do you use when fitting a RS turbo clutch as I have read the RS turbo one won't fit.

Yeah mate ib5 box will bolt direct into a fiesta, you just need to swap some of the studs that hold the gearbox brackets on from your old box into the ib5 one.
Pretty sure the lsd's do fit as ive seen ib5 boxes with lsd fitted
As for the realese bearing you need an ib5 one as it has a larger input shaft so the bc one is 2 small

So your telling me, that if i wanted to fit a rear started IB5 box in place of my front mounted starter BC box i wouldn't need to alter one cable?! Not even the main 12v live feed that comes from the battery, to the starter, to the alternator or the trigger cables would need to be lenghthened?

Nope, this is just plain mechanics. All cables reach it's just a case of routing them efficiently.
