USDM STI shortblock?'s

What will be the approximate compression of a USDM STI shortblock(EJ257) w/ US stock WRX heads w/ OEM thickness gaskets?
What else is needed if anything in order to perform this shortblock swap, as far as oil pan, water pump, etc?
Is this block physically larger or smaller than the 2ltr? Just curious as to whether my intercooler, wastegate, etc. piping will fit the same.
Sorry about all the ?'s, I just haven't looked much into this swap. Recent developements w/ current shortblock build have led me to this being the best possible option while I finish my other shortblock on the side.
Thanks much in advance,
-AK

I have the swap and from what most people say the compression is about 8.6:1 everything else will bolt right up, intercooler water pump etc....... to make things easier when you buy the shortblock just get the gasket set its just $200 more and you get every gasket . Just like ds baruuuu said the stock turbo will be too small....i have a vf30 and its still too small . Hope that helps
