I have an 2003 Evolution and I am rebuilding it this winter, and for my daily driver I am purchasing a 1997-99 turbo eclipse... I was wondering if when I take out the internals of the evo, I can just swap them into the eclipse. I was told that when you go to put in new pistons and rods, that you need to enlarge the cylinder by a fraction, or something to that degree....and since both engines are 2.0 liters, would the pistons and rods still work, or would I need a slightly bigger set?? and no I am not going stroker, so that isnt an option (even though it would be nice)... Sorry for the noob question, I did do a search before looking into this however, and I think I can w/out much problem, just wanted to get some directed answers...

thanks in advance!!!

 

the valve reliefs on the evo pistons dont match up with the eclipse motor

 

Evo 8-2003+ 9.0:1 compression (Evo 8 valve pockets opposite of 2nd gen)

thats what it says on wiseco's listong

 

Wow, i was thinking that this would be a good idea if it would work man that sucks.

 

Evo bore is 85mm. DSM bore for that year I believe was 85.5mm. Either way I know it's not the same bore.

 

eclipse bore is the same 85mm.
