without TPS dont even bother trying

the basic sensors need to work before the car will start

if you have the powerfc plugged in and hand conrtoller you can view ETC, SENSOR SW CHECK to see what sensors are dead (they will be highlighted in black)

main ones

TPS

AFM-1

02-1

WTRT

they are the critical sensors the ecu will need before it will start

Power FC works just fine in the 25GT Auto, it's just the auto GTt it can't run.

Most of the loom for the N/A will plug in just fine to the turbo engine 90% of the sensors are shared between them. The fact you're not running the factory GTt ECU is a big help as it's not going to have a fit that it can't see the TCS and other extras the turbo model has.

You may need to swap the odd plug over as I think the AAC valves were slightly dfferent, but basically google the R34 workshop manual and compare the diagrams and connect all the plugs up.

      I don’t really have any ideas how to set the timing on the CAS 😂, sounds like the top, sounds like it maybe misfiring as well as ticking,  got the box sorted 😌, must of been a air bubble on the clutch side

      Use a 2' length of hose (that's 2 foot, not 2 inches) as a stethoscope to localise the source of the ticking. From cam covers? From exhaust or turbo manifold gasket? From injectors? From lower down in the engine? Etc. Use a timing light to set the timing. Put Redline Lightweight Shockproof in the box. It's not the very best thing for the box, but it will take a box that refuses to engage a gear with other oil, and make it engage a gear. I had to put it in when I installed the R33 box I have in my car. It would not select ANY gear when running. Smurf jizz made it work. That was >10 years ago and I still use it. I'm stuck with it now. Failing that - rebuild the box.

      Well done Duncan. The fuel tank bulkhead lid is also in great condition (some of mine were stuffed). These are now out of production and good ones like that are becoming hard to come by.
