hi guys

i want to build my evo, since i read in this forum talking about using 4G64 crank, can stroke up to 2.3 ltr
i want to use 64 crank which engine bearing should i use the original 4g63 engine bearing / use the 4g64 engine bearing, or do u guy's have any other option
because when i saw both of them is different and also the 63 engine bearing is smaller than 64 ( 64 is wider )
and the 64 still using thrush bearing and 63 already one piece with the engine bearing

 

You are probably looking at an older 64 because the compatible 64 block uses the same rod main and thrust bearings as a 4G63.
