6 port na/turbo build oil + coolant turbo line questions
Hello all. I have already ported my turbo lim, and moved the turbo front cover over to the NA (so that I have an easy place for oil return.)
I have also had some custom fittings made so I can T off my oil pressure sensor and run a pressurized oil line from there to the turbo.
My question is: Where would you recommend I T off the coolant, and where should I connect the pressurised oil, pressurised coolant, an coolant return lines? Will I need to cut the stock metal tubes that go to the turbo? Although I am using the stock turbo LIM, the s4 na engine does not have holes in the engine for the water to flow through the LIM and go the stock turbo coolant line. Any ideas?
I have this as a hint/tip:
"oil lines:
as you can see in the picture above where i talk about the intercooler pipes, you can see that i installed an oil pedistal. these are mainly used for installing aftermarket gauges, but i used it as my oil supply line for the turbo. i made a custom SS braided line from the pedistal to the turbo, but you could use an AN barb fitting and run some heavy duty coolant line or something. for the oil return, you can use the stock location on the turbo front cover, just make sure your gasket is good or it gets messy
coolant lines:
this will depend on your setup. i used the coolant nipple on the back housing as the coolant supply for the turbo then routed it back to the nipple on the water pump. HOWEVER, if you want to use your N/A pump (it SHOULD bolt right up, but i never tried) you can route the return to the nipple on the back of your water pump housing."
But it doesn't really go into detail. What coolant nipple on the back of the housing? And the however confuses me cause he said he already did it to the back of the water pump but earlier he said he installed the turbo water pump.
..... so confused..
What would you do?
Thanks

oooo I just had an idea!
What if I T off the line that goes to the BAC, run that to the turbo and then return it to another T on the return size of the BAC? Would that work or is there something wrong with that idea?

the coolant line is under you upper intake manifold. Remove the UIM and run a hose from that nipple to the turbo. coolant return line runs to the nipple on the back of the water pump. It points towards the back of the motor
oil line- Put a "T" fitting where your oil pressure sensor goes. Its the round thing under your oil filter. Run a line from that fitting to the turbo. Turbo oil return line goes to a bung welded into your oil pan.

Awesome, so just so I'm making sure my logic is correct.
The coolant line that goes from under the UIM, goes through the throttle body and to the BAC correct? And the line going out from the back goes to the back of the water pump correct?
So I see no reason just putting a T before the BAC that goes to the water in on the turbo, and a T after the BAC for the turbo water return since that line goes to the water pump.
Also I have the turbo front cover for the oil return, and I already got the oil pressure sensor T'd off. I think I said that in the first post....
Maybe I Dont understand how a water in a coolant system works, but is the water pumps pressure alone going to cause the water to go through the T fitting before the BAC and cause it to go through the turbo instead of just going through the BAC? I just want to make sure the turbo gets cooled obviously.
Thanks.

Nothing against aaron or anything but some of the things he does scare me. He does everything to the extreme, and has the ability to put bungs and such in his radiators. I have the ability to go to car quest and get a coolant T fitting.

oh my ....
was going through my parts today getting ready to install the engine and I saw my old turbo waterpump...... ! It had an extra port going out/or in on the bottom of the waterpump that goes to the radiator. I look in my car now (where I have a turbo waterpump installed on a turbo motor) and it goes to the turbo!!!
I feel stupid, its going to make it so easy now to just use my turbo waterpump.
So my only question now isssss, is that the coolant return of coolant into the turbo? I'm guessing return because its so low, but I have been knows to be wrong more than right.
haha

There is a nipple on the rear iron, and a nipple on the water pump housing. Run your turbo between those two nipples.
Assuming you have your BAC and thermowax still installed, the line will also need to connect to them as well.
These are very basic issues and it kind of scares me that people turbocharging their NA can't figure these out, especially with the MASSIVE writeup on my site that covers these issues specifically.

thanks, yeah aaron ive read the writeup at your site hundreds of times (maybe not straight threw each time, but im always checking on stuff there) i didnt remember reading about the coolant lines, and also you did your turbo project a little differently, keeping all the NA manifolds and such so not everything applies.
id rather be safe, double check and look like i dont know what im doing, than just act like i know everything and end up being wrong.

exactly.. "you did your turbo project a little differently, keeping all the NA manifolds" .
i didnt, im using all the TII ones so not every part of your writeup applies to my conversion, which is why i need so much help lol

Fero313 just finished his 6 port turbo. The hardest part of the whole build was drilling and tapping the NA front cover for oil return. And even that was easy (for Garfinkle, LOL)
Actually, using Japan2LA's 6 port LIM made the swap stupid easy, worth the $$$ for Paul.

ugh lame, went to put on my UIM/TB and most the hoses/lines today but i just found out the NA secondary rail wont work with the TII LIM, so now i need a TII secondary rail.
its always somethin hahah
