Hi guys, and shop in my area is selling me an EVo8 engine and were not sure if its the MR or just the GSR....is there a way of verifying it, doe the MR engine have any marks or things that we can look at to identify the engine?

Also what is the main difference between the MR engine and the GSR engine?

There is no difference in the engine. The difference is in the transmission.

Evo 9's have MIVEC. Evo 8's dont.

^^exactly Motor is the same tranny, suspension and other differences make up the MR. Does the valve cover say MIVEC?

If its an 8 it shouldnt say MIVEC

^^Shouldnt but you can swap valve covers......

^^This is true.

There is no difference in the motor, if you have a VIII and buy a MIVEC motor you are screwed. If the valve cover does not say MIVEC and you think it is still from a IX then pull a plug. VII will have a copper plug and IX will have a iridium. It is that easy

^^ unless the owner of the VIII motor runs iridiums like me.... look for a mivec sensor
