Upgrading to my new gt28, one question

So I currently am set up with a Shit eBay turbo, but the seals blew out on it and its been blowing oil so ive gotten my gt28 just today in the mail. My question is, the way my Mbc is set up, (a hallman pro) the line that goes on the bottom port of the boost controller is pulling from the turbo I have in my car now via a nipple that is on the compressor side. My new turbo doesn't have said nipple or any of those connections, and I don't really want to tap into the turbo right now to get a nipple on it.

Where can I run that line to instead of off the turbo? Here's pictures to show.

Sorry the line is hard to see, its close to the radiator




And if anyone cares, my new gt28

Didn't I tell you that would happen with the eBay turbo? Make sure you run a .035" restrictor on the oil feed. And please dont run the oil feed line between the manifold runners. Im shocked it hasn't bursted and caused an oil fire. Its rubber or Teflon on the inside of the steel braiding.

In regards to your MBC, you can tap a boost source from anywhere between the compressor outlet and the intake manifold. Any place that see's boost pressure will work. Its also very easy to drill and tap hole in the outlet of the compressor housing.

I'm still on the same one that blew a few months ago, just took me forever to get the money haha.

And believe it or not, the "professional" tuning shop ran that oil line that way.. I just didn't know it was a problem, I figured it was ok since it was steel. I'll change it. They installed the oil line that way when they made my downpipe. Needless to say I'm not going there ever again

And as far as the oil feed restrictor goes, my oil feed line is already like a pin hole size on the end, but I don't know that its exactly that size. Is there any way to measure it or tell? I don't have anything to measure that small right now..

Since this turbo can be water cooled, do I NEED to rum water lines to it? A buddy of mine who owned a shop told me I might kit need to. I wanted to make sure before setting it all up. If I do need to, where would I want to pull that from?

Yes, its a requirement, not an option. Especially considering the cost of a Garrett GT turbo, you don't want to mess around.

You can get creative where you tap the water lines. Its really doesn't matter. The easiest would be to extend the hose that runs from the idle valve (from the throttle body area) to the front water neck on the head to put the turbo in line.

So it would go - idle valve > turbo > water neck.

This is how I set mine up and you definitely want to run these lines if the turbo is setup for it!

You have any pictures of your set up? I don't have an aluminum radiator right now, well I do but its not on the car because it is too big and won't clear the turbo.. so in hopeing there's a way to do this without running it to or from the radiator as I see most set up this way

It's raining outside right now, but if it clears up I'll take a picture for you. The line that goes from the throttle body to the coolant spout of the front upper radiator hose is what you'll be using. I think it's like a 5/16" line. You basically run a longer line from the throttle body to the turbo and then another one from the turbo to the nipple where it goes into the cylinder head if that makes sense.

What radiator is in your car? I've read that hooking the coolant up through the turbo heats up the coolant pretty bad causing you to need to upgrade to one with a higher cooling efficiency, is this true?

I run a half mount Koyo now, but I used to use a regular B16 Del Sol OEM half mount and it cooled everything just fine. You will be fine if you run it the way we suggested.

This should give you the big picture. Ignore the corrosion and whatnot. The car sat for a couple of months on the side of the house and it's been raining like a mofo as of late. Iol
