Thread: Are we sure regular SR20DE engines don't have piston oil squirters?

Every SR engines since time have the connecting rod oil squirters. They've been there all this time folks, nothing new.

If you've ever replace the rod bearings, you will notice there are holes in bearing shells. Those holes are for the rod oil squirters. You're supposed to line up the hole of the bearing with the connecting rod oil hole (rod oil squirter).

I've verfied this. Look at the sr20det FSM on Nico. It shows the squirters as well as the piston squirters on the oil flow diagram.

Also, do the OEM rods have an indicator showing which was it is supposed to be installed? It begs the question of how many people have installed the rods the wrong way.

Oh look aftermarket rods do have them, because they are not silly.

Am I missing something here. I don't see any oil squirters.

I see a small oiling hole on the small end side, yes? Must be a squirter, right?

Not a squirter. That is where the small picks up oil. I've seen them in different places on the end of the rod too. And initially I thought that's what it was.



Here is a Borg rod. Same position as the Manley rod you have posted. But lacking the oil squirter which is found at the large end.

I think (maybe?) our vernacular is not concrete enough to decipher which is an oiling hole and which is a squirting hole. (an oiling hole would squirt since an engine is under pressure anyway) I honestly do think this is silly since we ALL know an SR20 engine is over-engineered and designed to be beaten to hell and back. I think this thread is really splitting some finite hairs that may or may not need to be spoken about.

P.S. How much does that Borg rod weigh? Cunningham will make them at about 410-430 grams.

Subscribed, for the shrooms of course.

I'll agree with you kyle. It is getting a little silly for the context. However, I think some important info can come from this. Firstly the de rod that Ben says has the "squirter" pointed towards the piston. While the details rod that you posted look to be more like a 45. This will come in handy if Ben is correct. This will prove that a de motor, aside from the piston squiters and rod structure, is vastly in superior to a set. And I say this because if the de rod squirter faces the piston, then cylinder wall integrity is jeopardized when under a high comp or boosted application. Granted the many solid turboed De's over the years prove that yes, theses motors are vaslt over engineered.

Don't mind me though. This the beer talking.

Me neither.

Not if it doesn't see oil pressure. I don't think that hole sees oil pressure?
