1 : can i use 2.4 4g69 pistons and crank on my evo block 4g63 . can these pistons withstand pressure and heat?
2 : what kind of pistons can replace 4g63 pistons and work without problems ?

 

U mean 4g64 pistons in ur 4g63? 4g64 is 2.4l 4g63 2.0

Stock 4g64 pistons n rods rnt worth anything. These motors are naturally aspirated. The pistons and rods are no good.

 

This sounds right

 

he is talking about 4g69 which is a 2.4 that has the same deck height as 4g63...
Problem is, that is 87 mm bore which is a bit risky on evo block.. Also CR is a bit much for turbo engine on pump... I think it makes no sense..
