I already have had a turbo installed. (custom kit I made)I have removed it for the engine's current break in period. I know that some people would have just rather left the turbo installed while breaking in the motor, but I wanted to make sure everything was seated properly before I started tuning. Besides, I had ordered the stage two cams and totally forgot about them (took about 3 months to ship them  ) and wanted to see what they would do for a mildy modded motor. Of course the drop in compression isn't helping matters at all, But I had them and wanted to use them. Even with the drop in compression, they are a definite plus. But yes, I am reinstalling the turbo kit in a bit. Will also be running stock cams for the turbo use as the stage 2's are no good for turbo's. Tuning on a nice tight motor makes for a VERY small margin for error.

piper cams in UK now do a set of cams for the zetec designed for turbo use, they tested them in fast ford mag comparing to the stock cams and got 12bhp gain and a better power curve

Also why the drop in compression if you're running nitrous? Are you planning on a turbo install?
yes...block is cast iron no??

Yes, bottom is cast iron.

The block is paper thin though and easily holed. Once a rod snaps, it's all over, and the rods are weaker than the block. That being said, if deto is kept in check with either a cool enough air charge and good fueling and timing, or/and high octane fuel, stock rods and pistons can do around 300whp.
I don't know the differences with early model pistons vs new model pistons though. The V6s had weak ring lands in pre-2000 year models causing them to fail past 250whp or so, but that was all on pump fuel, don't know if they tried racing gas. But 2000+ models were good to around 270whp or so. All my zetec experience is with 2000+ year models and I don't know how the rings compare with the V6s.

Maybe for a dyno queen? I see 300whp on stock internals not lasting very long on daily to extreme load. Even if properly tuned.

Yeah, the one guy who did 300whp on 91 octane said it probably wouldn't last long. He has been runing on 250whp for over 2 years though.
The first guy who did 300whp on a stock block, did it with race gas and drove for over 3000mi(all on race gas) before deciding to build the block up.
I wouldn't run that much every day, but if you had 220whp or so then put a 50shot of nitrous on it at the track occasionally(on race gas of course) it should be fine.
