The conversion is hopeless, at least at any sort of reasonable cost. In any case, it's more than just a software flash away.
I know this is old but..
130i has a gs6-37bz - and a 3.46 final drive - 135i has the gs6-53bz and a 3.08fd (manual)
So yeah very different
And no i cannot fit the 135i rears with no mods.. Sadly lol
Ed: a quick google says the mt128i has the gs6-17bg?
