i was going to post this link but seeing your in asia im not too familiar with the shipping and compatibility issues.
Either way this seems to be one of the best bang for the buck short blocks. RalliSpec - Engine | Short Block
As for differences between the blocks im not 100% sure as im still learning more about these cars. From what most tell me there all pretty much compatible.
BTW if you already blew up a stock block id recommend a slightly built one like in the link above.
