So as promised, we start the extensive log of how to install an Ebay GT3582 turbo. The real issue is none of this is going to really bolt in. The only thing which bolts right up is the turbo to the manifold and that is only because I can demand both have a T3 flange. Other than that, everything is new and will have to be sourced or made.
Today I started with supplying the thing with oil and water. I am not interested in fitment as of yet so this is truly just, get oil and water to the thing however it has to be done.
These are what I have thus far. The oil inlet is a reverse flare of some strange size. Tommy at Kendrick happened to have on which goes to a -6 AN. The problem is, the oil feed off the head, yeah, it ain't -6 an, it's the normal flare fitting style. So I have to get a 90 degree to clear the exhaust flange and some adapter to make it all work. Should be no problem but ehh. The water fittings are however standard but I figured, let's treat this thing to the royal treatment. I could have just hacked up and reused the old banjo fittings, but screw it, this is an Ebay turbo, not some piece of crap Ebay turbo. I opted for the high dollar Earl's 14x1.5(1.25?) banjo fittings which I will press fiber line onto and secure with Fuel Injection clamps. The other hunk of steel is the return flange, but more on that, well, right now.
So I figured one of my problems with the last turbo, which is getting rebuilt BTW, was lack of proper flow out of the center cartridge. The hole on the cartridge is rather small but the one on the flange, even smaller. I am going to drill it out and tap it for a 3/8 NPT to match the flange I had made for the oil pan return.
Here is how the reverse flare of some strange size fitting sits. It will definitely hit the exhaust flange in it's current position, so I will have to clock it more and get a 90 degree bend for it. Again, it's -6 an and I got Flare on the hose. Another solution will be plotted for that issue, probably a -6 an fitting off the head, a few 90's and some SS braided. Seems easy, I'll let you know.
Here is the Banjo water fitting set in place. One of the fittings will point up, the rear one actually, and one will face down. There is logic behind this. First, the front one pointing up is not possible due to proximity to the exhaust flange of the housing. If it didn't melt the hose, it would surely heat the hell out of it. The rear fitting however has enough vertical clearance to make the bend required to get where I want it to go which is...
...right here. The inlet on the thermostat housing, where the hacked fiber hose is in this picture, will be the return side since it feeds directly into the top of the radiator. The feed side will come from...
...right here. This is the factory hard line which I am going to cut down, again, flare, again, and run a fiber line or -8 an braided under the center cartridge up into the forward water fitting, which is pointed down.
All of this is speculation at this point as I am yet to mount the thing in true fashion. I have temped it on the head but that's about it. I am sure I will have to mod the water cross pipe as the compressor will most likely interfere with it. Other than the oil feed line solution which I think I have a handle on, should be similar to what I described. For reference sake, all the stuff thus far has been around 30 bucks, fittings, etc. I expect another 50 or so for the line and AN fittings, maybe more.
The next major issue to deal with is the 2" hot side IC pipe being changed to 2.5". I have no desire to simply use a transition coupler so I want to find a full 2.5" solution for it. I can weld a pipe on at some point in the future once the car is moving again, but for now, the solution has to be something I can get cheap and local. I am thinking some large diameter radiator hose from Advance will do the trick. An issue I have is I need a full 2.5" 90 degree bend with at least one leg of about 6-7 inches. Most legs off bends are 4" max and that's too short. Another day however.
More to come.
