[quote name='knonfs' date='May 26 2005, 01:16 PM']What's the purpose of these two, and where do they connect?

Top One: Front Main Bearing Feed, Fed from the modified oil filter pedastal



Bottom one: MAin oil pump discharge: Goes directly to the oil cooler. It eliminates 3 90º bends in the oil flow path

Thanks for the info



One last question, does it needs to be drilled and tap, or just tap?

You have to drill out the factory brass galley plug, then drill to size and tap.

 

So Banzai, when you drill out the lower plug do any other passages have to be capped or eliminated?

 

Banzai...



Have you blocked the oil gallery going from the filter pedestal to the front bearing? I have just done these mods to my 13BT and will hit the engine dyno this week or the next.

Oil Pump gear sets.

FB 13B gear set 1.347:1

FC TII Gear set 1.5:1

FD Gear Set XXX:1 ????

13B-Re Gear Set xxx:1 ???

Anyone know the FD ratio?

 

If you connect your oil cooler oine to the "Discharge Oil Galley Tap", wouldn't it be good to put a bolt in the hole where normally the O-ring would be, by doing that you eliminate the possibility the oil ring isn't fully sealing..

No, you still need flow to the front relief. The O-ring problem is currently being engineered out of existance. Stay tuned

 

Do you really need a relief, isn't it possible to get rid of it if you make your oillines big enough till the rear housing where the oil pressure regulater is located..?

The front relief is to protect the oil cooler. It is set at about 140 pounds and in general use will never open. It has to be there for those few idiots that jump into

an ice cold car and scream the engine right off the start.



Adding the outside oil line from the filter adaptor to the front main gallery more than doubles the available oil path cross section. Plugging this gallery (the dowel gallery) inside the engine defeats the whole idea.
