I've never seen an aftermarket rod with an oil squirter. This doesn't mean they don't exist, but it would surprise me if they were out there.

The DSM oil squiter is probably not right for 3S block
DSM 1st gen Squirter
3S TT block
If we section a block we could determine if a better location was avialable, I like these squirters on a 300Z, But I have no Idea if there is an oil passage close enouhg to use this.
It would be interesting to see if a better quality squirter was available like this one for 944's

Oil squirters remove heat from psitons which helps to prevent detonation. I don't feel confident enough to remove them completely.
One other (expensive) idea could address oil volumn concerns too, convert to a drysump sytem that has enough volumn that you dont care if the oil squiters are stuck open. Replace the stock powersteering pump with a drysump oil pump that also has a powersteering pump attached
Or even a half assed drysump system could be used that would provide oil for new oil squirters, turbos, remote oil filters and oil coolers. This way all the stock oil pump would have to do is provide oil to crank, rods and heads.
I just realized I am getting into the practicality level of putting a Skyline transmission in a 3S, It never hurts to dream
P.S.

I used 20W50 at the NG03 Road Course. ALL of the local Porche Club guys strongly suggested this would give extra protection if oil starvation happened because of the banking. The car ran well and the lifters seemed quiet so I kept using this grade. The first day that the temperature was below freezing I got lifter tick (with 3rd gen lifters) so bad I thought I had jumped teeth on the timing belt. As soon as the engine warmed up the tick went away. A quick change to 10W30 eliminated this problem. I think the thicker oil is a little too tough to get through lifters. I might try 10W40 next.
