You'll need. Custom head gasket, adjustable cam gears, water pump spacer. Those are the big things.

I would contact the seller and return/ sell them back

 

Hi!
I sent 2 e mails but no reply.
I will try to sell them here in my contry but there is not many EVOs here, so I guess is my loss! )

Can someone tell me what is the best thing to do:
to buy a 4G64 Block and crank or to to to a machine shop with my OEM 4G63 EVO 8 ones and made theme with the 4G64 specs?

Thank you very much!

 

if you want to use those pistons you need to take them to a machine shop and make sure they are compatible with each other. If their weight is too different, they have different shaped tops, or they are for different bores then you will be SOL on using them together.

 

To be honest I had enough of disappointing, so I really hope that I will sell them.
I will try to find a bloc and a crank of 4G64. Machine them and after that another pistons!

my dilema now is if I should buy a 4G64 block or just machine mine (OEM EVO 8)

Thank you for your answer!!

 

If your block is good just use it. No sense in buying another block unless you can sell your current one to offset the cost.

 

To be honest, I do not want to touch the 4g63. I know they are rare and kind of expensive. That is why I asked!

Thank you very much for the support guys!
I really need it and it will really help me!

 

Can someone tell me please if this block and crank is working for a 2.4 stroker. Is it 4G64 engine??

Is a 2000 Galant!
