My DD ej251 in my 00 RS is going to die eventually. I have a set of ej251 SOHC heads. However junkyards around me only have ej25d engines. I want to use a EJ25D block with EJ251 Heads. Through my research here is what I found I need to use from what.
EJ25D; Short Block
EJ251; Heads, Intake manifold, Wiring, Sensors, Head bolts, Crank gear if reluctors are different
What head gasket should be used?
EJ251, EJ25D or I’ve read 11044AA642 which is for the STi, it is 0.7mm thick
What about timing belt tensioner?
I realize compression will drop, but is there anything else I should be aware of?
Thank you,
Kyle
