Bit the bullet and attempted a start up yesterday. I took a 12v supply off the ignition in the end, a black and red cable that initiates on first key turn, from looking at the electrical schematic it is linked to the alternator. Took a bit of priming and turning over but it eventually caught. Timing is off, no question so will wait on gauge before starting up again.
In the mean time I am working on the new throttle cable and linkage to the pump. I picked up some parts in anticipation for this, I got a link assembly off a surf or hilux (can't remember which) and it lines up with the bolt holes on the air intake manifold.
I'm using bolts to sit the throttle cable mount off its original position, the same with the link assembly. The HPD intercooler piece on the intake manifold has a nice flange on it that I can work off. Hopefully this will pass for mustard with testing centre? I'm using locking nuts to secure everything, just lining things up in the photos and getting the correct lengths to get everything to fit. I am using the original throttle cable, found it very difficult to get something to suit, So I have to extend the length of the cable to get it to reach to the linkage. Planning to use one of these

The gauge won't be here for a while so I am cleaning out the intercooler hoses and lines, I have a oil catch can installed recently so will be interesting to see if it the interior of the intercooler stays fairly clean. I also tidied up the boost gauge and EGT gauge cables in the cab, I ended up putting a switch in the cable from the gauge to the constant 12v supply which I was running from the clock. I think this was causing a parasitic drain (well hopefully that's the cause) the constant 12v supply is for a memory bank in the gauges but I don't really need that so happy to turn them on and off with the new switch in the dash as needed.
The previous intercooler has to be redirected a bit due to the manual throttle assembly so picked up a generic kit to get some more options on bends etc.
