This doesn't explain everything. But....the W58 5-speed Toyota box is now quite expensive, while the J160 Lexus is much cheaper and good for 300+ HP. That said, when starting out we thought it would be much simpler.
Shortening the drive shaft is the easy bit. But that's where it stops.
The top of the Getrag bell housing has to be used with the base of the J160 bellhousing - so this involves aluminium welding. We sent this out to a specialist.
The hydraulic release fork on the J160 bell housing is on the wrong side for LHD cars so you have to cut out a trap door - no big shakes. We then prepared a mounting point for the slave cylinder but at the end of the day I don't there was space inside the engine bay what with the exhaust manifold.
Mating the pedals to the hydraulic clutch is also a challenge as you need to find a place for the slave cylinder - eventually we found space in between the walls that make up the fire wall. I don't have pictures but I can get under the bonnet and show you. The slave cylinder came from a Honda or Nissan. It is small but does the required.
In short, chopping up the Bell Housings was the hard part and realising that a trap door/hole for the hyrdaulic release fork was needed - but it works. Is it cheaper than buying a W58 amnd getting a kit - who knows. I paid about $700 for the J160, and probably $1000 for the hassle. I sold the 5-speed Getrag without the bell housing for $500.
