I currently have a bolt on 02ws6 with 31k on it. I am wanting to do heads, cam, intake, and nitrous... Is it possiable to just swap out pistons and rods from underneith or does the block need to have some machine work done? Any light on this would be great....
Thanks

 

Take the engine out

 

I would go ahead and pull the engine if you are going to the trouble to change rods and pistons. You will want to probably rebalance the rotating assembly and do a light hone on the cylinders. Let me know if you have any other questions or need any parts and we'll get you fixed up!

Thanks!
