Today I got good news, the problem is a bent valve on the sixth cylinder, pistons are fine. Must have bent the valve when assembling the head ... . Since the engine is apart I've decided to do a full rebuild i.e. new piston rings, conrods and main bearings, valve oil seals, and so on . I've ordered the parts and hope to have the car ready by the end of next week .
Ed, I can maintain a rich mixture with no problem with the current injectors (6x630cc) and Megasquirt. I can even get it into the 10-s with no problem (currently it's tuned rich ~ 11.0:1 at boost, as a rule I start rich when tuning and then go back), I can also pull back timing . The engine compression is stock 9.2:1

those are massive injectors considering what boost level you are aiming for,
have you upgraded you fuel pump also? and what fuel pressure are you running? |

Good and bad, the good news is that the engine is ready and this Sunday the car will come out of the garage, bad news is that I wont be able to make the drag day since I have to break in the engine. Will keep you posted on how the car runs .

Small update, the engine is in the car and it's running very nicely (covered 150km ), however it's still detonating and I can't figure out why (timing is down to 19 degrees at 0.5 bars and AFR is ~ 11.8). I'm starting to suspect the Megasquirt setup (ignition part). Bad news is that something in the clutch broke Sunday so these days the gearbox has to come off, hope there is not a lot of damage. Btw does anyone have an idea of how I can measure the ignition timing with the timing gun while driving the car (i.e. under load) ?

Haven't updated in a while, the clutch problem is fixed. The problem was in the clutch bearing which had melted the plastic part (sachs bearing), swapped in a new one and everything is fine now. Whats left is to solve the detonation problem, hope to do that this weekend. Mean while today I'll disconnect the turbo hose from the throttle body and go for a drive to check if the detonation is boost related or not.

Finally good news. Today I solved the detonation problems, now I can drive the car in boost with no detonation. Problem was in the setup of megasquirt , specifically in the bosch ignitor setting .

I had a Volvo 740 Turbo for many years. It used a reduced compression ration, dished pistons, Bosch LH 2.2, knock sensor and, most importantly, a rising rate fuel pressure regulator. This means under boost, more fuel is injected. Did you use this type of FPR?
Just asking, maybe you already know.
