I would like some comments on a different type of oil drain. I know I could do the normal hose with hose clamps but I would rather do something like this.

This is in relation to a t28 gtir turbo.

Instead of the the normal drain on the turbo I would like to replace it with this.

I believe I will just have to enlarge the holes so the flange will fit.
I belive it presents a 1/2" NPT fitting so the next fitting I would use would be this.

That would have a 45 degree angle so it will point down toward the drain hole in the block. Then I would use a length of this hose.

The swivel 45 degree flex fitting would take the hose and make a nice snug fit. The end that plugs into the block I would like to use the same swivel fitting as before but I'm not sure if that would be the best option.

Opinions/Comments/Flames?

it would cost a lot less to use barb fittings instead of using AN fittings. i you want, i could get you all the fittings for the oil supply...
1 - 1/8" bspt tee, 1 male to 2 female

2 - 1/8" bspt to 9mm barb fitting (one for the oil pressure sensor, one for the block. the reason i use 1/8"bspt for the block is to keep the fitting sizes simlilar and eliminate any chance of screw up)

2 - 1/2" npt to 9mm barb fitting

I'm trying to stay away from the barb fittings so I don't have to worry about them leaking later down the line.

I figure spend the money now and do it right.

You don't want the 45 right out of the turbo. You want it to head straigth down out of the turbo and then have the bend later. Having a bend right out of the turbo can be enough of a flow restriction that the oil could stay backed up in the turbo which is bad for the bearings.

Then why does the stock oil drain fitting have a 45 degree angle right out of the turbo?

The stock drain has a 45 degree angle on it. Well maybe a bit more.

You have to remember its a gravity feed, its not pressurized so you have to have some sort of downward bend or it will get backed up like you said.

What I'm trying to accomplish is the same thing the stock drain does but without using a hose with hose clamps.

It would definately look good with the A/N fittings but I doubt a barb fitting for this application would be prone to leaking simply because it's a "drain" and not pressurized like david mentioned.

I considered the same thing for my T3/TO4E and I think I need the first item you posted. I've decided on a NPT to barb fitting for the turbo drain. You can see the fitting I JBWelded into the block in the top left of the pic below:

For the oil feed to the turbo I will splice into the line coming from the oil filter relocation so the turbo gets freshly cleaned/cooler oil. Let me know if you want the A/N part numbers.

hmmm....... can't quite remember what the drain on my t25 looks like. Damn, haven't had to look at it which I guess is a good thing! Well, i guess you want the oil drain line vertical because it's draining because of gravity.

Hey Jody, so whatcha got going on there....

1fastser, you JBwelded a fitting to the blcik and your worried about a leaking barb fitting?

I never said *I* was worried about a leaking barb fitting...that was a response to david's comment: I'm trying to stay away from the barb fittings so I don't have to worry about them leaking later down the line.

And, trust me, the fitting will not leak. It is a professionally done ghetto job that far exceeds the infamous scoop. ;)

Hey Jody, so whatcha got going on there....
Same as you Khiem, "a few tweaks here and there... :)"

Take a gander...

ohh im sorry, i read you wrong. hey you got any close up pics of your JB weld oil drain. did you ever consider using a sort of silicone instead. something flexible so it doesnt crack, but still holds in place.

I don't see why it's necessary for silicone. It's not rigid or under tension, just a drain hose from the turbo. I'll try an take a pic.

Jody

So, does ANYONE make an oil feed and drain kit for the T25/T28 setup? I would like to buy some!
Travis

Julian, here's a pic of the JBWelded oil drain. Factory, I tell ya. ;)
Note the "cast iron grey" paint...daddy likes.

Where can one purchase this piece from? I need one too!

The drain from the T3/TO4E turbo looks like this:

I need that piece david...where, where, where!

laterz....Jody

Is this the fitting you need?

turbo drain (http://www.store.yahoo.com/sr20performance/t3oildrainfl.html)

Or carve one out of a steel pipe floor fitting from Home Depot for $1.25 ;)

Cheers,
Charlie

Looks like the one...Thanks Charlie.

I just emailed Louis.

1fastser, has the oil drain been tested yet? i would hate for it to crack. as for the oil drain flange, look on ebay and search for "t3 flange". i got mines from there for $16.00 and it looks a lot nicer.

What makes you think it would crack? It's not like I JBWelded a cracked rod. There are no forces acting on the drain and heat is not a problem.

Thanks, I'll check ebay for "t3 flange". What's nicer about yours? The one Louis is selling (posted by CharlieH98) is a billet Al piece.

the reason im worried about it cracking is because of the different expansion rates of the aluminum and JBweld when heated.

...not worried...till it happens...don't think it will...we shall see...

...nothing on ebay
