i have a 97 gsr block and was going to sleeve it for 84 mm. question here is what crank rods and pistons do i need to make it a 2.0. when i research at eagle they have 3 different sizes for crank and rods. i was told ls/b20 but want specs of the ones i need. other question is do i use ls pistons or gsr pistons.

 

I wouldnt put stock pistons in a sleeved block, if im spending the bread to sleeve a block, Im going to use forged pistons and rods. Pretty sure to get a true 2.0 youll need to use an LS crank, and rods that were designed to be used with an LS crank. LS crank, you use LS rods. GSR crank, you use GSR rods.

 

For true 2.0 Litre, B20 or LS Crank (with B20 or LS Rods), they are the same length. But this is only if going to sleeve to 84mm

 

So on the forged pistons are the wrist pins in the same location for a ls and Gsr preferably talking about cp 84 mm 9.7:1

 

So is the Gsr stroke 3.4330 and rod length 5.430 and for the ls it's 3.5040 and 5.394
