New Garrett for my Slant 6!!

[finnman1]

First of all, i'm planning on putting this garrett in my 74 slant 6 dart. I plan to use an intercooler, 2 bbl. intake and junkyard-pick 2 bbl. carb. I read thedodgegarage.com religously and this website http://www.slantsix.org/articles/tur...bo-article.htm which is the biggest help. I got it off a TI 87 newyorker, which i bought for $150 since it had a bad fuel pump. Anyways, I got the turbo off today and i never seen any oil lines; only coolant lines. actually 3 lines w/ coolant in them. No, the headgasket was a steel fel-pro and was fine. In this website, it shows how to plumb the oil lines on his mitsu. Does the garrett not have oil lines cooling it? anybody know exactly where these mystery oil lines are? a diagram maybe? sorry, was a hectic day, probably just didnt see them by chance.
thanks,
chris

there are ALWAYS oil lines. If they all had coolant, then the headgasket probably WAS toast.

There are two coolant lines, they go into Brass "L's", the oil feed is a small metal line that screws into a brass adapter on TOP of the turbo body, the oil return is UNDER the turbo and connects to the tube on the back of the block.

[finnman1]

So, in laymen's terms, the oil lines are on top and bottom of the rusty iron side, and the coolant lines are in between the rusty iron side and the aluminum side?

[TonaChris]

Is it just me or would you guys be leary of that turbo if the oil feed line was full of coolant?

[Phreakish]

if the oil feed was full of coolant, YES, I would NOT use it

The turbo lines should ALSO go into the center section of the turbo.

top and bottom are oil, left and right are coolant. Thats how the connections at the center section should be oriented (ignore the ...)

Post pics when you get it done. I have always wanted to turbo a slant 6 in a nice, light Dart. Sounds cool. Keep us posted on your progress.

Wow, no offense but you need a research ALOT more if you don't even know that oil lubricates the bearings of the turbo not cool it. Oil is the life force of a turbo, without it it will burn up in a matter of seconds.
Also, if you don't know that the ''aluminum side'' is called the compressor housing and the ''rusty iron side'' is called the turbine housing you need to stop and think a little. In between the 2 housings is called the center section as phreakish mentioned, this is where the oil and coolant go in.
How are you mounting this turbo to your slant 6 exhuast manifold? You'll need the exhuast manifold off that same engine you got the turbo from to cut the flange off and weld it to your manifold. Do you have a heavy duty welder or have access to one?
How are you going to add fuel for the boost? The carb isn't just gonna compensate for the boost alone, well maybe 1-2 PSI if you jet it rich.
Where are you going to get the oil supply for the turbo from? Are you gonna hook up the coolant lines or just let it go?
And there's many other questions you need answered before you even attempt this. Research more, specifically how turbo's work.
Here, I'll get you started-

go down the the tech section on the left and go to turbo 101.

Sorry if I sounded harsh but you REALLY need to know more before doing this.

Wow, im sooo sorry moparzrule! It was late at night after going 32 hrs. w/ no sleep and crying babies and 12 hr. shifts at work. Excuse a friggin me if i wasn't thinking clearly as to what the 2 housings were called. This is the first time ive pulled a turbo off an engine before, let alone put one on a slant. Have you ever tried this?... there's a first for everything and i'm learning as i go. Isn't that why this forum is here in the first place??

ANYWAYS.. First of all, there wasn't coolant in the oil lines. (delusion taking over)...Setting this up is pretty well explained in the aforementioned website. I'm just trying to figure out how to plumb this, and what the various components are there for. Like... the one in the pic. Do you guys think the two round canisters on the left are even needed with a carb setup? Should i plug them off? What are they for?
Thanks guys.

That's the EGR stuff. Lose it.

[moparzrule]

The pic is of the EGR setup not needed.

Sorry for trying to help, you still obviously have no idea how a turbo works. If I were you I would atleast find out the basics before attempting to turbo something LOL.
Have I ever tried this? The answer is YES so back off. You obviously didn't know what they were called, stop using staying up as an excuse.

[finnman1]

also, what's the steel line running from near the exhaust pipe off the turbine housing to the bottom of this in the pic? it runs across the whole assembly. EGR too i presume? Is welding these holes shut too primitive?

[moparzrule]

EGR also, welded shut is fine.

[finnman1]

done, hacked off, pinched and welded. also, egr crap off, made and bolted on a piece of sheet metal to cover hole. Thanks for identifying those as egr...common sense really.

Call me old fashioned, but there is no way in Hell I would attempt to bolt a Turbo to a carbed car ANYway! I took in a Turbo Trans Am years ago...was near mint, but ran like crap. Why? The Carb would just flood the engine with fuel, the turbo would lag behind, and maybe, sometimes it would work. All that with 60's engineered spark advance and fuel delivery technology in an 80's car..it was a disaster! I dont see you ever getting it all to run, much less being streetable...I am following on several other site how guys are Turbo'ing cars that were not originally made that way, and the only thing that made them work, was the fact that the electronic mgt. systems and fuel injection compensated for the newly found compressed air....that the found/bought Turbo's that they have installed will function.

Junkyard Turbo, bolted to a 2bbl carb? I see disaster looming....and at best, a loud pop, and an engine fire!

Hey, I had very good experiance with a couple of carbed turbo vehicles, my dad's 1966 Corsa 180hp and my own 1963 Jetfire. Both of these setups used sidedraft 1bbl carbs. They pulled through the carb and force fed the engine. The Corsa used a Rayjay, later TRW turbo and the Jetfire used a Garrett unit with a wild wastegate control similar to the 84 Chrysler setups. The trick would be either find a Jetfire carb (unlikely) or a big SU (HD8) from a Jaguar 3.8L or early 4.2L XKE. Pull through this and feed into the stock intake on the slant 6. Slants have a real good long runner, plenum chamber type intake. Then use a Grainger valve for boost control. Jetfires used a regular vacuum advance plumbed behind the turbo, Corvairs used a "pressure retard" unit. You don't want more than about 30 degrees total advance under boost, maybe only 26-28 due to the long stroke of these engines. Keep in mind, you only have 4 main bearings, and a cast iron crank + if I remember correctly a 4 1/8" stroke for the 225. Good luck with it!
