evo 9 pistons on eagle rods

[dan2288]

I know the rods can handle a lot of power but how much can the pistons handle? Will they hold up to 500whp? I want to go with the evo pistons because I just want to drop them in without needing to get the block machined for other pistons like ross or weisco. Will I be ok with just a hone and dropping the pistons in if everything looks ok?

similar situation... why not just spend the money on doing a nice full build instead of cutting a corner and saving a buck..

I just want to make the bottom end more reliable and dont have the time to spend doing all that. This is my only car so I cant be left without a car for a week or two.

Regardless you would have to wait a week or two whether it be taking your block apart again to machine the block because of your rings not properly sealing. You should bore and hone the motor with oversized pistons to allow the rings to seal properly. Just sticking factory sized pistons could be bad especially with an aged motor, the cylinder walls won't exactly be in spec. It would be safer and cheaper to do it right than find out the hard way. Especially if your looking to make good power out of the setup.

ok well not sure how many motors they have built but you can just mic your cylinders and make sure there in spec and not out of round cut the ridge off the top if there is one and then hone your block....then mic it again and make sure its still in spec if so then your good there is no reason to bore a block unless needed to...once again NO REASON TO BORE UNLESS NEEDED....im doing a cheap build right now to stock bore 2g pistons on 1g rods i understand that money is a problem along with not having another car....hope this helps u guy and good luck

What are the chances of a 20+ year old block with quite a few bit of miles on it still within stock spec? If he is looking to take advantage of those rods and pistons he can't risk the hole thing going just because he couldn't bore and hone the cylinders properly.

4 cylinders are naturally balance and don't wear near as much as a v6 v8. Keeping your oil changed also deters wear. Mine had 177,000 miles on it when I rebuilt mine. I mic'd the cylinders and they were still in spec. Honed it out and dropped standard bore pistons back in.
