Don't go 40 over unless you have to... on a turbo block bore it over as little as possible. That extra .15 liters (No, I didn't bother with the calculator for that number, but if you need we can) isn't going to gain you anything that's worth the extra meat between the cylinders... the 7M's cylinder walls are fairly thin as it is. I'd keep the walls meaty and add the whopping 1/2psi it'll take to make the same increase in power with a manual boost controller.

If you just want stock, Toyota or NPR are good. The NPR are available with a molybdenum coating too. Personally, at this point I'd put in something forged (never know how power hungry you'll feel in a couple months

).
