thoughts on removing oil injectors?
I am having an engine built by Ocean @ Chikara right now and he suggested removing the oil injectors and that he does this on nearly every build he does. I am going FI (Rotrex) and just wanted a second opinion or some input. I trust him with basically anything Miata related but he builds a lot of N/A engines where it would make sense to remove but what about an FI engine? He said his 1.9L N/A is running extremely high cyl head and egt temps (higher than most FI engines, the way he tuned it) and said if his car is fine mine will be as well.
Any thoughts?

FM mentions on their site that their pistons are designed to be able to remove the oil squirters too.... apparently it is a common thing.... that was all that i could find out though.
Maybe call FM and ask them why you would do it, and what their pistons do to offer the ability to remove them.
Im not an FM part *****, but i noticed this when flipping through their catalog.

If you have forged pistons, you will be fine if you remove them. The mitsubishi 4g63-T came with oil squirters from the factory, however many rebuilders omit them when building motors with forged bottom ends with no negative side effects. This also allows for the use of non-turbo cores (no oil squirters) for building new motors as factory turbo motors can sometimes be hard to find for a decent price depending on where you are.
*EDIT* I'm not saying you SHOULD remove them, I'm just relaying what I've seen on other platforms.

Here is the paragraph where FM talks about not needing Oil Squirters.
The skirts are given a moly coating for low friction, and there`s a ceramic coating on top of the piston to protect it from the heat of high power. This keeps the heat in the combustion chamber where it makes horses, not in the oil where it makes the baby dinosaurs cry. We also designed them to run without the factory oil squirters, which gives higher oil pressure, lower oil consumption and higher power levels due to a drop in pumping losses.

You're negativity is kind of irritating me. Do some research on who this guy is, and then tell me he is dumb after. He chooses to run "dangerous" that's fine. AFAIK he also has build the highest HP 1.9L N/A in N. America just chooses not to flog it all over the internet.
