Swap'D Motorz

I have eg coupe with JDM GSR swap, im going to turbo soon but was wondering which is a better setup im using Weisco($350) 81.5mm 9.6:1 pistons(or CP($400) 9.7:1) with eagle rods and garett t3/t4 57 trim. so which is better to throw them in? i have b18c block or b20 block... and what is good crankshaft to use? lookin to get around 400 hp its my first boosted b series and need a little help/advice thanks... good setup or different internals?

b18c... don't boost the b20 the stock sleeves suck...
