 |
|
I am going to have Porsche oilsquirters on a type 1 TF-1 case engine. Crank is scat flanged all t4 mains.
From watching the pictures, it looks like i need type 4 bearings that have OD groove, ok?

Yes, and a little 'carving' on the bearing to line up the oil supply. I used a dremmel with a small burr.
i can't remember if it I got it from the instructions with the pic you have, but I used a tapered drill so I could tap the squirter in firmly |

If your oil channel is located at the bearing ID, merely drill four small holes outward lining up with each squirter. A tapered 1/4" drill is the way to do it .. but use a small end mill first to start the hole straight.

Bearing options are then:
-Silverline T4 bearings and alignboring to T4 size
-BMW style T1/T4 bearings and modifying them for oilsquirters
-Scat bearings? Do they have bearing kits with T1 OD and T4 ID for flanged cranks?

Trying to learn something here. I see the hole for the dowel pin and another hole for what I think is the oil to the main bearing. Where is the oil squirter. It looks like the oil supply has been tapped for an orifice of some sort. Or is that the squirter squirting out the backside of the web to the piston.

the first pic shows the squirter in the hand next to the hole it will be placed in

You are looking at the right side of the case only in these pics. The left side is the oil supply side, but its not shown in these pics, Notice its only showing the center main pin. The left side has 3 of them and an oil supply hole on every main. Hope that helps.

Yes, the nozzle is a Porsche 911 nozzle, and squirts from the back of the bearing web. They have a small check valve, so they only operate at pressures above idle. A very nice design, but they are now over $30 each, used to be under $10 from what I've read. It's that damned P-word that makes the $ go $$$. |

Sorry about that, John  I found a T1/T4 adapterbearing pic from my old post at cal-look.no, looks like this might fit with squirters.

I can't imagine why so much material would be removed from those bearings. Only a small connecting hole is required.

Is that particular BMW shell the right dimension both out, and inside? Or is lineboring/grinding necessary?

that looks like the adapter that JayCee sells. I believe it fits a standard bore type 1 case and standard type 4 journal

Those adapter bearings have such big holes from the package.

go to aj sims his oil squirter will work at low rpm and above. the Porsche style will only work at 45psi. the draw back is your oil will be hot like mine 240*  ps. I have dtm shroud and type4 oil cooler.

Your oil being hot likely has something to do with AJ Sims being in your case - Note - He's been banned for a reason. Enough said.

Roger Crawford said that the Porsche pistons had a pocket under the piston that the oil went into and the idea worked but with standard pistons it causes oil problems.
But i havent seen on most porsche pistons any pockets, stock or aftermarket.
