Hello guys.


I have here 4G63 block that I was told that it was from Evo 8.


but how come my evo 8 water pump is not covering the cavity of coolant passage?


please tell what 4g63 block I have.


im assuming its from 2003 4g63T jdm outlander, or jdm evo 8 block?
but not positive.



Thanks



This is the original pump



With new water pump. See the exposed cavity?

 

It's an Evo 4 block.

 

Handy thread here: http://www.evoowners.co.uk/threads/mitsubishi-lancer-evolution-engine-codes.2401/

You got the worst bottom end of all the rotated 4G63s.

 

wow, that F***** sucks

 

And Why is that?

 

Prone to crank walk, ring, piston issues that were said to be sorted in the Evo V and up.

 

Even with fully built?

Forged rods H manley
Wiseco Pistons
Acl bearings
Evo 8 crank

 

Other than the prone to crank walk thing the rest is bogus as far as I'm aware. I've had 4 blocks apart side by side to a 5, 6, and 8 blocks and have seen no difference in regards to pistons etc. I believe the part numbers were even the same.

 

an 8 block would have a balance shaft belt area near the crank pulley

 

Can one simply use an evo 8 block and evo 4 head? I was planning on building my evo 4 and wanted to just use and evo 8 block....

Other option would be to use an entire evo 8 motor....but would the evo 8 motor bolt up to my evo 4 transmission and tcase?

 

Nevermind.
