ScottyB Wrote:new factory, sealed EJ257 shortblock is like $1500 from subaru NA.Any need to replace the top end on these engines? Getting a long block vs short block for example? The performance engine i was looking at also said they came with the sti crank. This was for an ej255 btw. Is the sti crank that much better? If i do it, ill want to shoot for like 350whp with upgraded turbo and what not. Would there be any benefit getting the 257 and would it come with the crank? From what i understand, you could use the 255 head on the 257 block cause its the same block with a different dome shape, right?
budget another grand for stock-fitment, stock compression forged pistons and installation before the engine ever sees the inside of your engine bay.
install, carry on. this is the standard procedure for any factory shortblock now, the stock pistons are a known quantity for their weakness at this point.
Scotty, learn me on what i need to pull all this off and if its worth it.
