ok so i ordered eagle rods and jdm itr pistons for my friends ls/vtec. how are we supposed to make the pins stay in the rods?
any help would be great and thanks ahead of time

 

You'll need to have a one or two grooves machined into the piston for the retaining clips.

It's easier to just use a forged piston already machined to use the wire locks. They would be easier to install and they're lighter, stronger, blah blah blah, etc.

I don't know if it's possible, but depending on the rod and wrist pin diameter, maybe the small-end of the rod can be rebushed to allow for an interference fit instead of full-floating.

 

honda pins are pressed in...but with eagle rods i'm not sure

 

yeah now the pin just falls out the other side where would i be able to take them to have them cut?

 

Do as IN VTEC said and have the bushing machined out to run a factory wrist pin or run forged pistons. Buying some aftermarket pistons is a lot easier and if the ITRs are still new you can probably find someone to buy them. Just my $0.02

 

the pins that fall trough the rods and pistons now are the factory ones.i really dont want to use aftermarket pistons because i want the engine to last as long as possible so i wanted to use factory pistons. i have looked at the pistons and i think it could be done to just need the right machine to do it
thanks

 

Oh okay got ya, you're right then that's not going to work. Well I guess you have two options. Have you had bad experience with forged pistons? Just curious because of the majority of street motors that we build today I'd 90% of them are running forged pistons and they seem to hold up just fine, even under boost, etc.

 

just sent the pistons to reputable machine shop, they can groove the pistons for you
