Scratch that, I was diagnosing the original ecu incorrectly. Plugged it back in, it's giving me code 21 for ignition.

Replaced the Power transistor with my old one after cleaning up ground points etc still had code 21. Then started getting code for maf. Removed and tested the maf with the battery and multimeter, all ok. Then tested the loom, all ok.

Installed the ecu from my old et, ran it for a while and now getting code 44. Everything all good!!!

HOWEVER still spluttering and backfiring but not as much as before. I'm lost now guys...

Can someone confirm timing etc?

Update!! It had a random fuel filter on it, replaced it with my old filter and now revs up to red line with no spluttering or backfire when driving!

However acceleration is so bloody slow like misfiring but not 100% on that. More diagnosing to be done. Any suggestions fellas

Cheers for checking the timing Tim! Turbo seems fine no smoking etc so I'm just assuming...

Does the turbo make good boost? could it be jammed or tight? Many of these cars have been stood for long periods now so it could just be that?

Turbo does spool up when stood still can even hear it chatter when throttle is closed quickly so I reckon that's alright.

Got myself a timing light, going to give the injectors plus leads a once over a bit later today.

Here's a question, when setting the timing is this correct:

Bottom pulley to 15 degrees
Set distributor to one gear out to the notch and install

Or set the set the bottom pulley to 0 tdc and then align the dizzy to give me 15 degrees when the engine is running?

Cam timing was out by about 180 degrees. The previous owner must have aligned it with the wrong timing Mark on the pulley. Sorted now and acceleration Is all good

Schutz applied underneath, sills surface rust has been treated and painted up a bit. Insuring it tonight and will be my daily for a while!

Cheers mate, I was shocked and had a mini panic attack and thought there'd be some major damage somewhere but got away with it!
