Yesterday, I had a bad night and one of my pistons died on me
Looks like it is time to build the block

The #4 cylinder wall was damaged a little bit and it looks like it won't be gone even if I bore the block 1mm

Therefore, I will need to get the Darton Dry Sleeves. (I am overseas and can't get an empty block here so please do not suggest me on getting another block)

My goal is to have an engine that can run 600whp w/o any issues

1. What CR should I go with?? I was thinking getting a 9.5CR with a Cosworth HG
2. I was planning on getting 85.5mm pistons but someone told me not to since it won't match the head. If it won't be a problem, then I will consider the 85.5mm ones to stroke the engine to 2.1lt
3. I will list the part that I am planning to get. If you have any suggestions other than the ones I list, please do so...

Here is the setup I have in mind:

Darton Dry Sleeves
CP 85mm 9.5 CR Pistons (for long rods)
Carrillo 156mm H-Beam Rods
