Where to install on oil return plug

[DammitBobby]

On a S13 where is the best location to install the oil return plug? If it is possible do you have any pics?Thanks

If you mean the oil return bung that gets welded to the pan, I weld them on with the center of the bung on the drivers side of the pan exactly 6" back from the front body of the pan (not the flange) and 7/8" from the underside of the top rail. You will find it to be pretty close to the spot weld that holds the windage tray in place. This will place the return between the front of the motor mount and the back of the AC compressor. We do things the best way at http://www.phatka-t.com / http://www.sound-performance.com and actually use AN fittings and braided steel line so what is pictured here is a steel weld on -10 male fitting.

Thanks Ivan that is exactly the info I needed.

Do you mean 6 inches and 7/8 on center, or to the edge of the fitting? Is it really that important?

[IvanAtSPRacing]

Yes, if you carefully read the first sentance of my post you will see "center" is mentioned. Yes, its its important to get it in that spot if you want to be able to get a line on the return fitting without interferance.

yeah its important to get it right, I did not measure correctly for my second drain and it contacted the engine mount, so now I need a new oilpan to do over. Its a lot easier to take the time to do it right the first time.

sorry for bringing up an old thread but i just have a quick question that I dont think deserves a new thread. just want to make sure the pan is steel and not aluminum. I would assume steel since you guys welded a steel bung. TIA

[DammitBobby]

Yes it is steel.

[andrave]

its steel, but man I didn't notice that 10 AN bung before ivan, thats nice... I'm using 1/2 steel bungs with 10 AN adaptors, but yours is a cleaner (and more space efficient) solution. where did you get those?

[IveBeenBad]

Ivan, where do you mount oil temp and pressure senders in your KA's?

[Jookmasta]

ya where did u get the AN adapter which u welded to the pan? was it an Earl's fitting or something similar?

[DammitBobby]

Here is the pick of the BD oil return setup

[Jookmasta]

hey rseabrooke, did u also use an AN fitting? or did u use something else? where did u get ur fitting from?

[DammitBobby]

I am using the one that comes with the Stage 1 kit from BD. I really don`t what it is to tell you the truth but you can ask PJ at Boostdesigns.com.

[Jookmasta]

i was thinkin about the placement of the plug and did a little research. seems that the other resources on the net say that it needs to be only 3 inches from the front and about an inch down. this info comes from nsport. now i know that judging from the pic that ivan posted, it seems that there would be no interference from how the plug is set by ivan's directions, but which is best? i figure that the location of the plug really depends on the mani that your using but for us DYI people that are piecing together custom kits, this could make placement of the plug a difficult issue.

BTW, i already got a pan tapped using Ivan's directions so this is really just out of curiosity.

[DammitBobby]

The location that Ivan gives only has one problem. The return bung covers one of the bolt holes for the oil pan. So I modified the measurement instead of 6 inches I moved it back towards the front of the pan 1/4 inch. I did this and had to grind the air conditionar bracket to allow room for the return line. I couldn`t install the return line because it was touching the air conditionar bracket. Notice the picture it is a tight fit.

But can you do a 90 degree turn to the back and then up to the drain?

what if i install the drain plug a little more toward the back?

[DammitBobby]

It will be a PITA to weld it further back and you will have problems with the motor mount being in the way. I would stick with what everybody else is doing. Working on the oil pan is the hardest part of the project!

[npaulseth]

Nice skyline you have in the background.

[Jookmasta]

ur absolutely right as the bung does partially block one of the holes for the oil pan but if it does eliminate the grinding of the AC bracket, isnt it worth it? im pretty sure i could still get the bolt or screw or whatever it is that goes thru the hole to get in there with a little "persuasion".

And yes i hear from everyone that the oil pan really is the hardest part of the project.

[turbo90]

seems to me, about 7/8 of an inch on center down from the flange is all you have to adhere to (to miss the windage tray== SAME E/DE). adjust given your custom instal, look at your N/A motor to judge the distance back from the front of the pan

[DammitBobby]

Yes I had to grind some but it really wasn`t that much. I rather be able to get to the bolt easily. Either way it is going to be a PITA.
