alright i have a question that maybe some one could help me with. i am going to rebuild my 5sfe engine and i have a set of 40 pistons for a 7afe laying around. they are brand new with the wrist pins and rings. could i use these on my 5sfe engine if i gave the pistons to the machine shop and told them this is whats going in. any help would be great. thanks

I know the walls will be a bit narrower but after this build I don't plan on rebuilding again. If these pistons will work then it will save me some money and get my build a little closer to finish. I'm not going to be turboing or anything crazy. Just looking to make it a reliable car for my wife to drive. I'm picking up a motor that runs with 165k miles and it's knocking in the bottom end for 100 bucks. So I figured I would drop her off at the shop to get the cylinders bored and honed put in some new rods and mains and ur normal timing belt water pump oil pump and valve stem seals. If these pistons will work then I would say it's a go.
