G13BB engine differances

Hi guys i wonder if any kind soul out there can help , i have a 2002 softtop auto with the G13BB engine in it unfortunately i have the melted version so am on the look out for a replacement . am i correct in thinking that the G13BB in the auto softtop is different than the G13BB in the manual version either soft top or tin top ? In other words do i have to source the said G13BB from a auto soft top or will any connect up to my auto box ?
also i am in Hampshire and wondered if any one might have a spare that they would be willing to sell !! longshot i know but worth asking
thanks if anyone can help

Any should do as long as you have all the parts outside your existing engine to swap over to your donor. The more alike your donor is when it comes to sensors and electrical, that it is period correct so to say, the less problems. you can even use engines from other suzukis. I would without a doubt use the g16b engine. Could be some hassle with adapters and engine mounts and oil pan, but there is a solution to it all and help in here for it everything.

Edit: auto or manual you can reuse your existing flywheel or auto torque converter.
