420a oil line install

[Jeff99GS]

Okay I am ready to install the Braided SS oil lines for my turbo 420a
I have a few Questions about doing this. The guy I bought it from said to drill and tap the oil pan and thread the bolts right to the pan to secure the oil return flange.....Is that oil pan thick enough to really get a good thread on it?? I think it needs a backing plate thats got nuts welded to it...but I'm not sure. Or can I just put nuts on it from the inside of the oil pan.... will it leak? should I just get the flange welded on? it came with a gasket, will that gasket be good enough or should I put some RTV silicone gasket maker on there to prevent leakage?

Any tips on doing these oil lines for a 420a would be great!!

I need help with the supply line too, I have been told to just T- tap off the oil gauge sending unit??? is that correct??

conceptillusions.com sells a kit for this... Drill the hole in your oil pan. You use a flange that your braided line screws into. It screws right into your oil pan.
for example check out this picture here:

Thats how i did mine and it's never had any leaks or problems

As far as your oil feed line, get a 3/8" threaded T fitting. It goes into your oil pressure sending unit hole which is on the back of your block on the left side below the freeze plug.

Thanx man!! that picture is worth a 1000 words! How did you run your oil supply line? did you T off of the oil pressure sending unit into the turbo

Oil Supply-- this is one way you could go:

Or you could just go through a regular T fitting, however i'd recamend filtering the oil but you dont have to. I ran the T fitting into a filter then through my braided line and into the T fitting for my turbo.

 

[Jeff99GS]

Damn thats a badass block man....so what kind of filter is that and where did you get it? do you think that could restrict oil flow and starv the turbo for oil? Thats a good Idea though! clean oil is good oil!

 

[htaracing]

haha that's not my block, but it is really nice. i didnt take pics of mine before i put it in, wish i would have. Here is what i would recomend. Run your regular T Fitting from the block then run into a filter and then to the T fitting on your turbo. Here are some pics of what you'll need

I do believe thats what ya need here is the website i got mine from:

I'm not sure about the other T fitting starving the turbo for oil... probably wouldnt but i dont wanna steer ya wrong. I can only speak from experience of what setup i used. I'd recomend calling Slowboy Racing and asking them what fittings you'll need exactly so they dont get mixed up. Or call Concept Illusions and ask them, they're probably cheaper.

...lowes has all the fittings you need

That thing on the right of the T is the sending unit for an electric oil pressure gauge. That would be the best way to go....T the block, oil pressure gauge on one side and feed line on the other...you don't need to keep the factory oil pressure sending unit sensor dealio, all it does is activate the dummy light in the dash (which of course comes on too late and is useless when u have an aftermarket gauge)

Hope that helps

The tee won't starve the turbo for oil at all. The 3/8" fitting that threads into the block is much larger than the actual 4-AN line that feeds the turbo.

NO no I meant would an oil filter off the Tee starve it for oil?? cause that other guy suggested using a filter on that line. would a filter slow the flow of oil to the turbo?

 

[VelocitàPaola]

Probably not... the 55psi+ oil pressures often found in feed lines are usually more than enough pressure for a turbo. A high-flow inline oil filter shouldn't reduce the pressure/flow that much.

I don't see the need for a secondary oil filter, though. The primary oil filter does the job just fine; a second filter won't do anything but complicate things.

 

[XMasta19]

+1... you don't need a secondary filter, it's just more of a hassel to have back there.

Well im working on my turbo kit right now (almost done by the way ), and concept will give you everything you need for your oil lines for 150$ and SBR will give you all of the fittings for 65$ ( I bought mine from SBR). It was cheaper for me to go with SBR because i was able to buy the hosing from autozone for 45$ steel braided. I was going to get all my oil line stuff from home depot but i was a little leary when someone told me that there lines wouldn't withstand the kind of abuse i was going to be putting them through.

Wait a minute here. .. You actually REMOVE the stock sending unit? I thought you just removed the sensor and tapped into it. There would be 2 outlets, one for oil pressure gauge, and one for oil feed, correct? If I weren't using an electric oil pressure gauge, would this outlet from the tee still be of use? I doin't think I'm going with an electric oil pressure gauge, but I could be.. What other types are there? I know standard and electric..

But wouldnt the standard require a line to relay the oil pressure up to the gauge?

Sorry for the confusion, I've got everything for my kit except the gauges.. Just wanted to clear it up before I " BUY IT NOW"... ... dont act like you don't know what I'm talkin about

"On the driver side of the back of the block there is a bright grean plug. you must first slide the red lock to open, then pull the plug off. use the socket to remove the stock oil pressure sending unit. i didnt have any oil come out but it wouldnt hurt to have some towels handy just incase. the 3/8 nipple screws into the block. next put the 3/8 tee on that. on the back of the tee you can reinstall the stock sending unit. on the opening left in the tee, put the 1/8 reducer in. then the 1/8 to 1/4 flare fitting. the SS 4 -an line attaches to the flare fitting. now on my turbo i threaded the oil feed hole for 1/8 NPT threading. i then got a 1/8 NPT elbow, and connected another 1/8 to 1/4 flare there to feed the turbo. Make sure you use teflon paste on all of these connections." I am quoting this from gsgoinfast from his forum on building a turbo kit for the 420a.

yeah, um, i got all of my fittings and lines for my feed at home depot. i got a stainless steel line that was for a dishwasher (really looked like it was going to work) and it keeps leaking from the emmense heat . other than that, the fittings and everything for it is solid, no leaks.

as for my oil return, i used heater hose and the flanges from a 1g and clamped them to the hose. works good until it hits the oil pan then it leaks pretty bad. i ordered new ss oil lines from www.turbo-supply.com. DO NOT cheap out on the oil lines.
