TB42 carby and EFI engines are basically the same but unless you are technically minded and able to do the EFI conversion yourself the cost involved would far out weigh any benefits.
Converting from carby to EFI would involve sourcing and fitting the complete inlet manifold with throttle body, idle up solenoids etc, airflow meter and airbox (good luck finding an airbox in good condition), electronic distributor, wiring loom and relays, high pressure fuel pump, filter and lines, accelerator cable, and probably a few other bits and pieces. It would be cheaper to sell your pre '92 Patrol and buy a post '92 model instead.
Scott, if you are interested in turboing your original engine talk to Darren (Blackers) at TJM Coopers Plains. Last time I spoke to Blackers he was just finishing off and tuning his TB42E turbo.

Thanks mate - appreciated, but at the end of the day, I only end up with a turbo charged engine that still has just on 300K on the clock and whilst I take care of it, it is bound to let go at some stage, and as per Murphy's law, that'll be at the moment I most need it!!!! Hence I'm going for full replacement ...
hey big rig, what did you do in the end?
Yep - due to arrive today ... I'm going down to check it all out later and give it a hug!!! lmao
