This is great. What size is it compressed?
Would you recommend bothering ARP bolts/switching to studs or just stock items will do?

Apparently the block is taller on 1.8. I have shim-measured it again and the clearance is 0.6mm. I've also just found out the piston's got a bit of an inward dome- that's even better for me! Did you have any luck measuring it's volume? I'd guess it's not much at about 1 additional cubic centimeter but even this 1 c^3 really help in my case!

I'd hope to use "regular" which is 95 octane here, but i believe it's not the same scale worldwide, may be it'd cope with 91-92 worldly-known octanes or something. This one is the most stable here though. 98 and 100 grades are also available but quality may vary and actually i don't think these would give a lot more timing advance for the hassle. I think i'd trade ~20hp off for less chance getting bad fuel and ease of finding a pump.

Sorry i'm totally unconfident in turbos. The only thing i know is it's from some nissan (probable VQ or VG) and i've got to hot housings: 21u (0,46) and op6 (0.58). Later one is now bolted in. Am i good?

I'm 100% not gonna map a boosted setup myself. I'll have some dyno time and a man with an idea how to map cars do it

Thanks, i'm really watching forward this as it's my first engine build (although not fully done by myself) and also this might be the only tuned zetec in this huge country, not to mention there's about 5 zetec powered sierras and most of them got running with my build advices after i've got mine going
