Head down to your local hydraulic hose store and they can make you whatever you want. I've always ran 6an for an s400. Usually runs about 40 bucks to have a stainless braided line with all the fittings you need made up.

I have a set of oil lines for a twin kit. Only problem is you'd need to adapter to tap into the valley turbo feed and an hsp turbo bracket for the drain line since they drain the oil threw the bracket. Then out the bottom of the bracket to an oil line to the upper oil pan.

What are the fitting threads for the feed line at the 475 and where should I tap the keg?The drain I can magiver.Thanks for trhe great info,Cant wait to bend some rods

I believe borg Warner uses a 1/4"npt for the oil inlet on their s400's. I can't remember what fitting I used for the block. But if you look down kind of by the manifold passenger side at the front of the motor you will see a plug. That's where I feed my s472 from. I will see if I can snag a pic of it in a few.

I think the thread for the fitting on the block oil feed is m14x1.5

Thanks for the great info.helped a lot,Only have the drain left to do but have to figure out how to plumb it in.How is yours coming along?

 

[dirtydmax]

Does the drain have to flow down or will the pressure push it down?Just brain stormin as I will be finishing up today and looking for other options and thanks for all the good info.feed is in and looks great,will post some picts when done.pulled the bolt from block and it was a 1/2'' npt.

I'm not aware of any 1/2npt oil galley plugs on the engine block...you sure your tapping into the right spot? And yes the oil return needs to be straight enough/high enough to gravity drain itself or else you will pump the compressor housing full of oil.

I hope I tapped the right spot!It was a 19mm plug I pulled,i was suprized when I pulled it it was that small but I got some oil dripping so I ASSummed it was right.My 475 drain is not tapped but can it be done or should I make a bracket up with a bung?

Post a pic of where your getting your oil from

On DF there is a thread on oil feed for twin setup with a pict,I went by that pict,check it out if you don't mind and let me know if I should move mine or its ok,heading out to do the dump so I might be a bit before I can repost,Thank you very much for your help!!!:hug:

 

[mike diesel]

This is where mine is tapped into. Passenger side towards front of engine.

Got it mocked up while I wait for the rest of the parts,boots,flanges+bands ect.Welds need cleaning but its all functional.I was unsure about my oil feed due to no leakes anywere and got scared so I put feed line in a water bottle and fired for 3 sec,took 1 sec to fill bottle and the other 2 sec ended up on the floor.sorry for the poor quality picts.

 

[mike diesel]

Well if it's pumping oil then i guess your good. I hope your not using those worm gear clamps for the boost tubes. Those will blow right off.

 

[dirtydmax]

Just mocked to fire,still waiting on all the good stuff as it takes forever to get anything.Got my clamps but waiting on boots and the v band for dp.Still undecided on intake though.Thanks for the guidance along the way.:hug:

 

[dirtydmax]

Well took it out for a shake down tonight and couldn't believe how it performed,going from a strait pipe lb7 this thing was strangely quiet with the 475 until I got on it a little and than it sounded like a jet,unbelievable difference in every aspect of how it performed and this is on a stock tune,so now im on the hunt for some info on tuning for a twin setup and what my next move should be.More fuel,air or just bite the bullet for rods?Any suggestions will be appreciated.

You can make your rods live but you won't be getting full potential out of your setup. It all comes down to what you want your truck to do and how much your willing to spend
