250 crank might be feasible, I think your roadblocks with your setup are being undercammed and you need a good header not the stock JDM one. With your setup you're probably cheating yourself out of 10hp just with that header, and with 12:1 c/r you could be running Pro2's instead of regular Stage 2.
But I digress...here's the build I'm getting started on right now which will replace the stock B18B in my 98 hatch:
B20Z block/crank/rods
ARP head studs, main studs, rod bolts
RS Machines 84mm pistons, 11.8 c/r
all new ACL bearings/thrust washers
GSR oil and water pumps
Greddy t-belt
Fidanza flywheel
CFR aluminum underdrive crank pulley
GSR head
SKunk2 original style manifold
AEBS 65mm t/b
JG 296/300VT cams (like a CTR+ profile)
JG gears
Buddy Club springs
Crower steel retainers
fake Mugen valve cover
NGK blue wires
GSR tranny
Mr. Gasket hi-torque starter
chipped P72 ecu

to make max power out of that setup, your goin to need a bigger...infact a way bigger cam profile then what ur running a stage 2 of any cam really should do u nicely, you have way too much compression to be running a almost stock oem cam.

I know, when I bought these I got a smoking deal & they were advertised as being JG 308/316 cams which are almost like Crower stage 3. But the guy didn't know what he had and they are much milder. They have basically the duration of CTR but higher lift. I ended up getting a partial refund and keeping the cams.
I didn't want to go this high with the c/r, I was going to keep the stock PHK pistons which would give me around 10.1 c/r with the GSR head then these would have been nice, but when I learned I'd have to machine the pistons for valve clearance I said forget it and got the RS Machines pistons which only come in one compression ratio. I also thought it would be safer to keep the stock rod/sleeve B20 block in the 8500-ish range.
There was someone on HT who wanted to trade some S2 stage 2 cams for a set of ITR or CTR cams for a turbo setup. I was trying to talk him into trading for these but for some reason he was bent on only OEM so that didn't work out. I know I could go even bigger but I'm kind of broke and real hot cams everyone wants are hard to find good deals on.

Pockets are much, much shallower than that. I'm unemployed at the moment, not to mention right before I lost my job I got scammed out of $670 which I never recovered from. So there's the cams right there. I'd love a set of Pro2's. But isn't that what they cost from Skunk anyways? And is the cam trade-in policy still going on? The credit to trade up any aftermarket cams to purchase Sk2 cams is more than I can sell these for...if the offer is still going on. But I'm still too broke for that even.

haha, I'm still hoping to resolve with non-violent means. He keeps saying he's going to refund me but he just needs to sell a couple things to raise money. Been a while so we'll see if he makes good or not.
Yeah I'll keep peeping HT, I'm patient so I may score a good deal...
hold on............this is an all motor thread first of all...but your gonna run s2s2s with 10 to 12 psi AND a 50 shot on a stock bottom end
? that thing is gonna pop plus why would u want all motor cams for this kind of setup? you will have crazy valve overlap with that duration
