how do you think "normal" motors get the pin and cylinder walls lubed?
it comes from the rod bearings.. that sprays onto the cylinder walls, then the oil control ring forces the oil on the cylinder wall through the holes in the piston to the wrist pin.

This motor being a 2.2 isn't seeing a ton of R's, nor is it daily driven. It will be a fun weekend/light duty track car.

Agreed.

Eh.... I don't like the idea of getting rid of the oil piston squirters. They are there in the first place as a reliability feature. They help cool the pistons which in turn can help reduce the chance of detonation.
If the car will just be used as a DD with little time spent in the high hp range, then it's probably okay.
But to eliminate them to increase the oil flow to the bearings is thinking backwards in my opinion. The solution I would have gone with is a bigger oil pump.

I dealt with the question of removing or keeping the oil squirters back in the day on my boosted B series motor. Even though I ran forged pistons, I opted to just leave them in. On primarily a street car, I'd certainly leave them in. The oil spraying on the bottom of the pistons is (obviously) meant to cool them. People say it's to reduce detonation by cooling the pistons, and since many OEM mfrs run them, I figure it can't really hurt (better safe than sorry imo). Hondas generally don't have main bearing problems, so I tend to think more oil pressure isn't necessary, but it certainly can't hurt.
Basically, seems like some people remove them, some people keep them. Seems like you can't go wrong either way.
Like wadzi said, the squirters are not the way oil gets on the cylinder walls. Economy cars don't have oil squirters, but many performance engines do.

If you spend anytime at all researching other BIG motor builds, and I'm talking about guys making 1000whp+ on smaller honda motors than us, the first thing they do is block them.
If this car was DD or not, I would have done it, they aren't needed and imo a few extra psi of pressure and cooler oil temps is a much better trade off @ this power level.

High performance engines have them, base engines do not. Like a regular SR20DE does not have them, but the DET does. I think everyone would agree the F20/22 falls under high performance, and it has them. Do you think the Honda Fit has them?
Following the train of logic that high performance engines have them, and non-performance engines do not, it follows that the oil squirters are there to aid either performance or reliability. In this case, I'd say reliability.
For a car that only spends short bursts at high power levels, then they probably are not needed because the engine does not get heat soaked, i.e. everything gets hot. So on a drag car, you don't need them. Like on a drag car, you don't need a bigger radiator or an oil cooler. The car isn't run hard long enough to heat soak anything. On a road course car, you certainly do need all the extra cooling.

Sweet build. Motor looks stout. Ill be sure to block my oil squirters when i do my build this winter. Also, if you decide to sell the ELT, ill be happy to take it off your hands
