I think tranny is different from sc and is, but I could be wrong.

The motor should bolt right in as far as I know.

yeah, but use the SC's computers, etc, because the trans is different (I think) and it might cause some funny business. But, it should bolt right in.

put engine in, use sc harness ecu sc trans drop in plug and play. done.. why r you swapping them? does one have 200k miles and one has like 10k?

Use the SC harness , ecu , trans and the rest of the stuff the trans is not the same .You have to change the motor motors because the IS300 uses some weird one. Swap the oil pan because all lexus and toyota rear wheel drive 4doors are front sump and all the rear wheel drive 2doors toyota and lexus are rear sump so you need to swap the complete oil pan setup.

Just use the long block only , and transfer the rest of the stuff .Tthe stuff may look the same but it's not !!
