1) Thats probably what 40 degrees past TDC then, highly unlikely its DET.
2) As above.
3) Possibly, I don't think i'd build another engine and worry about it.
4) Yes, the 1 that failed on us at probably 520hp blew the whole cylinder wall out, highly likely it cracked, pulled some water in and hydrolocked.
5) Yes probably more luck/quick to diagnose a problem etc. I reckon it probably cracked when running a full chat on the last pull or something. The crack worsened as it cooled and it obviously pulled some water in when cranking it over.

Yes it seems likely that it started to go under load, then opened up further as it cooled down.

Shit bit of luck, but at least it didnt damage any of the valuable components.

Saab 93 2.0 lump mate (the B204) - the one based on the shared GM platform

It will bolt straight up to my VX220 turbo gearbox, needs different flywheel to use my clutch, new loom to work with the autronic, new engine mounts, cam sensor adding, new manifolds etc, but thats all stuff that can be relatively easily achieved.

Bad news mate but personally think if you can find the time and the money its worth another shot. Most likely just unfortunate and maybe next time round you can get hold of a block with a background.
All the best.

For now im just going to lob a fairly basic spec motor in it that I can quickly build from spare parts I have, as I want to do bedford.
Then moving forward I need to decide if I stick with the LET engine, or go over to a B204/B234 Saab lump.
The B234 is very tempting just because its still a square engine but is 2.3 instead of 2.0, which will spool the turbo that bit sooner
