oil feed/return setup something new, i swear ;P

[DRIFTEADOR]

I tried explaining this to wd earlier, but a customer came in and by the time i got back he signed off. I was thinking about running an oil cooler right after the turbo before the boiling oil goes back into the motor, and at the same time make the feed/return plumbing a little easier/cleaner.

my mspaint skillz:

green lines are for the oil cooler, you could have the same setup without it, but the reason i came up with the idea was to have it.

The sanwitch adapter looks like this:

i know its not the best picture. basically it installs between your block and oil filter and has a 1/4" port (for oil feed line so you dont have to tap your sender unit) and your choice of -6an, -8an, or -10an fitting (I'd go with -8an since most scavenge pumps i found had 1/2" ports which translates to -8an. -10 isnt necessary like on gravity fed setups; technically you could have a -4an return and have no problems with puddling because the oil would be pumped out the turbo).

bump....I hope someone knowledgeable chimes in... the only problem with this is will the pump pull too much/ little out of the turbo... also I guess the pump is electric what happends if it fails? just my 2cents

ya someone with more knowledge can chime in................i think that kapower has a good point. should the pump fail, ur turbo is gone. While with a traditional setup, the gravity fed oil return cant really fail unless the line fails or gravity fails. its a good idea but is it cost effective and does it really improve efficiency?

[WDRacing]

OK here's the deal, It's almost exactly like I have mine right now. Which is completely operational. Have the pump mounted anywhere on the return side of the oil system, it then feeds the oil through a cooler, or not up to you, and back into the valve cover.

Here's a bonus, I'm going to make a maniold type thing, well eventually, but in the mean time, if you run the oil through a cooler, it will cool off the valves springs which will enhance their ability to rev.

It works like a champ and you never have to worry about the return line being big enough or at the right angle...and no more drilling.

aha, the secret is out................reroute oil return to valve cover. i guess pics and part numbers are the only thing missing.............

[vvaffle]

I'm still a little confused on the exact details but that could be because of my lack of knowledge. No need to spend more time explaining it to me now, but once you get the whole setup done WD, I would like to see some pictures, with arrows pointing out important parts if possible.

[PapaSmurf2k3]

wow, this is a lot like my system that i thought up, except mine didnt have the pump for the return line, or the oil cooler. great minds think alike?

[kapower06]

thanks for chiming in WD. What kind of pump should we look for if we attempt this setup. Does it matter if the pump goes before or after the oil cooler? Also were at on the valve cover do you have the return line plumbed to? Sorry for all the questions but Im about to start my kae-t build. Thanks

THe pump is the whole point of the system-the oil isn't going to just mysteriously flow uphill.

[DRIFTEADOR]

there is little to no pressure at the oil return so I'd think you'd want the pump as close to the turbo as possible.

WD, so you didn't drill into the vc? what's the flow rating of the pump you are using? the one I'm looking at flows 7.7gpm which obiously the -3/-4an line wont be able to flow. will that be a problem? would it be a good idea to upgrade the feed?

[virus77]

It seems like its easier to do it the conventional way, no pump involved. The oil pan isnt too hard to deal with (with a gasket), I even used a bolt on oil return bung with no welding and it hasnt leaked one drop of oil.

[WDRacing]

The way I have mine setup...is WAY better then the traditional pull off the pan, drill a hole and install a bung. For one if the line ins't exactly the correct, you blow turbo seals, several of our members are forced to run 2 quarts low just to keep the oil "gravity" draining.

The pump I have is only 2.8 GPM and will pull liquid from an elevated position 12 feet away. I tried it out to make sure it would work. So I have the pump mounted next to the fuse box, the other side is to hot and crowded for my liking.

You should look for a Shurflo pump, they are used in the RV world for water pumps and such. But many people use them for Methanol, so oil won't be the slightest problem, plus its a run dry pump, meaning it won't burn itself up by running dry. But please try to limit the amount of time it has no fluid flowing through it.

[kapower06]

WD could you please post up some pictures of your set-up, things such as the cooler, pump and drain in the valve cover. also what kind of lines should be used? Is it possible that too high flow of a pump could actually suck the turbo dry if the feed doesnt flow as much as the pump pulls out? hope thats not too cornfusing...lol...on the brightside if you could match the flow of the feed wouldnt that take away lots of stress from the seals and allow a faster spool by having a higher flow of cool oil on the shaft and bearings? thats all I have for now...

[turtl631]

Is it possible that too high flow of a pump could actually suck the turbo dry if the feed doesnt flow as much as the pump pulls out?

That would require the pump to create a large amount of vacuum...very unlikely.

This won't change the spool time at all. That doesnt even make sense.

[ILikeMy240sx]

WD... you would still have to drill the valve cover right? Otherwise you would use the PCV nipple but I dont think that would be a good idea because of blow by...

[kapower06]

Hey turtl631 what I said was in question format, sorry to confuse you, just an idea that I thought about. thanks for correcting me, im used to it.

The easiest way to get the oil back into the motor is to drill a hole into the oil cap!!! Just like I did, then thread in an elbow and BAM!!! Instant oil return...

Now why didnt I think of that??? lol WD you rock!

I cant wait to see pics of your setup and how it runs.

[WDRacing]

You got any more pics of your car? Website maybe, I like the B-Kit.

[erollinc]

i want pics and part numbers! sounds like a great idea

[DammitBobby]

Crap! I wish I knew this last year save me a freakin headache with all the dam trouble of getting that dam )(*&)_&_(^ pan off and crap! Fixing leaks as well!!

Werd...

Exactly the same setup as me. But I also put a good amount of gasket sealant on as well.

That's suprising... Not many people do but Ive grown used to it. Its about an inch lower now which makes the car look alot better

These are the pics before Nismo S-tune kit went in.http://www-personal.umich.edu/...4.JPGh ... u/...1.JPG

[ILikeMy240sx]

I think the only problem with having the oil return line hooked up to a pump is.... when the pump fails. I would definitely have some sort of device to make sure that the pump is operating... or a way to route the oil somewhere else when the pump fails.

[onosqv]

The oil return bung, bolt-in or not, where are you guys buying this? I realized after I posted requestinga pic of the oil return bung that I was trying to put an an fitting as a bung, whoopsies .

That's suprising... Not many people do but Ive grown used to it. Its about an inch lower now which makes the car look alot better

Plenty of ppl love that kit... back in the 90's, hahaha.

That's the Vader/Shogun/Veilside style body kit yes?

I have basically the same kit (front & side skirts) for my s13 (I didn't choose the kit, though). I've gotten relatively used to it, too.

for any type of fittings or tees anything related to plumbing something go to mcmaster. They really have the cheapest and the fastest shipping all around

[Craving4Boost]

Just wondering....do you HAVE to take off the oil pan to put an oil bung? is there any other way (maybe cost more money) but yeah is there?
