I want to add more displacement to my evo 8 4G63 motor and was wondering if 4G64 crank(100mm) will fit since there are a lot of those cranks out there for sale

 

Yes

 

I believe there are more technical details than simply putting in a larger crank. Engine size is what displacement is not necessarily crank size alone. The block is bored larger in a 4G64, meaning that the pistons are larger and heavier, thus requiring the larger crank.

 

It will fit you must modify your 2.0 slightly depending on rod selection, orr in any case perhaps. there was just a thread a couple days ago on this

 

85.5mm bore + 100mm crank = 2.3L that everyone talks about.
86.5 or 87mm + 100mm crank = 2.4 that everyone talks about.

Heard of a 2.3L? That's the combo to get you there.

Aaron beat me to it.

 

what rods do u need to use with the 100 mm crank.

i was told u can use a 4g63 block with 4d68 150 mm rods and 4g64 100mm crank with vg30 pistons
