So what are the specs for this one? Bore, stroke, rods, CR,... don't have to tell all the secrets but give us something. ? BTW, how much you managed to shave off the weight of the bare block? half a kg?

Ah dimensions… they are so boring ;j

well it’s tad under 1800 cc ? 

I’ll start with weight issue. Bare block, just main bearing caps & bolts on my bathroom scale said 37.5 kg. So something over half a kilo is close. Should weight std block with better scale. Maybe i find some time to do this.

Come on, that's just teasing us! You must be using 80mm crank then. Did you consider shorter stroke ratio, like using 2-liter S14 crank? I've thought that as an intriguing option but I have no idea about pros and cons in turbo app.

Confirm. Yea S14B20 crank was my first thougt - have one brand new on a shelf. Maybe i’ll that route someday. So far this concept has worked very well.
