You can order the ej257 and the gasket set for a 2005 that's what I did.
The ej257 is aboput $200 cheaper then a ej255. They say it has a better crankshaft. You will get the current version of the ej257.
There's my thread.
199,000 May 12 new ej257 short block, Aug 11 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. CHECK your oil, these cars use it.
