The bottom end of My high lsvtec build plan is to use a b18b block, and stick in my USDM b16a2 pistons to get 11.9 Compression.
However if you use USDM b16a2 pistons you will only get 11.31 Compression Ratio, However if you JDM B16A Pistons you will get 11.53 which is almost the same as a JDM ITR Piston.
Basically you will want to swap out pistons for something with more compression. I would also recommend arp rod bolts as OEM Rod bolts are a known failure spot. Its cheap security.
Play with
This, Its a B Series compression Calculator.
A Type-R Intake Cam would also be a good addition. The Type-R Exhaust cam only adds an extra 1hp at peak, its worth the extra money IMO. If you decide to go with the Type-R Cams going with Type-R Valve springs/retainers on both sides is a good idea as to get the most power out of them you will rev to 9k.
Hope this good you some good ideas to start from.
