I have a used airresearch turbo for my landcruiser. But there are three AIN fittings on the topof the turbo and one radiator hose thingie on the bottom.
I need someone that knows a bit about turbos to give me a hand. Anyone know any good sources???

oil feed in, oil return to engine, and ???

What's the model # of the turbo?

It is a Garrett Airresearch T04
Which seems a bit large for a motor that never reaches more than 4000rpm....

I think the hose thingie is for the oil return. Does the t04 have a water cooled option as well?
That would be nice...

Also, the AN fittings were connected to what looked like hard compression fittings. redneck engineering??

Also, the carb will be an impco 425 propane unit. So gas issues will be diferent

Yes, they had a water cooled center section option (after a quick look on the net). I'd guess the center fitting is the oil supply and the other 2 are the coolant IN/OUT. Have fun with it.!

Tick Tock Tick Tock...:flipoff2:

Both the water & the oil will require 2 fittings. One for in & one for out.
I would guess the AN fittings are the oil in/out.
The other hose may be for a pop-off valve.

ask superrunner

On my T-03, the oil inlet is on the top, and oil outlet is on the bottom. The water inlet and outlet are on the sides. The oil outlet should be much bigger than the inlet. Turbos tend to whip lots of air into the oil thus they need a bigger outlet. The water fittings should be the same size or close to it. You should be able to blow air through any of the fittings to determine what is what.

Yuck..
But a good idea!!
Thanks!

ANy good blow up diagrams of one of these things??

turbo city has lots of good info about DIY turbo installation

good luck.

Are you going to rebuild it? Looks like it was leaking a little oil at one time... A garret To3 is tiny, more for a 2 liter sized engine, but the T4 might take a bit of RPM to spin up...

What is the a/r on the turbo? It should be stamped on there. Usually, the 04 doesn't spool until 3k or so, but there is a lot that can change that. I'll second Grandpa Jeep on the oil and coolant lines. A rebuild would probably be good for a turbo that old. Are you gonna go with an intercooler?

Probably no intercooler. The Propane going from liquid to gas should reduce the intake temp fairly well. But I will probably put a snorkle on it to make sure that I have ambient air instead of under hood temps..

It is an AR 60 T04
Does that mean much??


The oil leaks were more from using a compression fitting with the AN fittings. I think it seeped quite a bit..

I think the top AN and bottom radiator hose thing are for the oil with the side fittings for coolant. Coolant lines are easy. but what should I run the oil lines off of??

It's pretty big. Can't give you any details, but TO4's are generally sized for larger displacement or Hp engines.

You got it. The "radiator" hose fitting is the oil drain. The oil pressure source it opposite it. The drain when you install it needs to remain at the bottom.

The water lines are on the sides. Either one can be the inlet/outlet. Tie one into a water source like tee'ing into the water heater hose. Run the other up high to the top of the radiator. Don't worry about pumping water though it. It's purpose primarily is to cool the turbo after the engine is shut off with a convection current. Sucks water from the low source, heats it, forces it out the other side through the high line to the top to the radiator.

For oil source, you need pressurized oil. Try looking for plugged clean-outs along the oil galley in the block. You might be able to replace a plug with a fitting for the oil source. If you have a remote oil filter, you can tee into that as well.

The oil drain has to enter the block or pan above the oil level in the pan to keep it from backing up.

Have fun.

on the Dodge Daytona's they took oil from the oil pressure sending unit by uding a T..

Any one know any details about the AR60 desigination?
This is going on a 4.2 liter six. I hope it boosts below 3 grand..

doesnt the liquid to gas thing occur in the lock off or somewhere other then the intake?
the 100 octane rating will be turbo friendly

Jason,

the bigger the turbine, the higher the revs you'll need to spin it up... I'm not really a turbo guru, but if you could find data about the car it comes from, it would greatly help. If it's for a larger engine that revs higher, then you may be disappointed :(
If you want some boost low in the revs, you may want a turbo from a smaller engine.
For instance, I'm planning to put a garret T2 turbo from a 85c.i. petrol engine revving @ 6000 onto my 3.4L (212c.i.) 3B diesel engine. The max. boost will be set up at 6 psi, and that boost should be achieved all the way from 1500 to 3000 rpm. I'll have to lower my. max. revs because the turbo wouldn't handle all the air flow above 3200rpm, but otherwise it should be OK. I'll have to install an intercooler, too, because the small compressor would heat up my air pretty high, which would cause the engine to overheat...


HTH,

The liquid to gas does ont happen in the mixer. But it still is slightly cooler as it enters the mixer..

The turbo was set up for a 2F motor from what I understand. I have no idea what it was originally designed for.
The 2F has a 7.5:1 original compression ratio. I can run a TON of boost with that compression ratio and not worry about detonation with 115 octane.

AR60 desigination???

this sounds like a cool project, id like to make an attempt at turbo-ing the motor in my rover one day, with something small since redline is about 4k :D

I have a Garret T3 on my yota and it has oil in, oil out, water in, water out all inbetween the compressor and the turbo...

Here's a pic before plumbing it up:

So is the cruisers ;)


Here is a pic in the engine bay...


AR60????

the largest fitting will be low pressure (likely) and oil return directly across from that will be oil in (high pressure)

perpendicular to them will be water in and out, you don't have to run the water straight away but it is better to run it!!

i wouldn't worry about it spooling up before 3000rpm, i think these guys, are thinking a 2.0litre cant spool it!

you have 4.2 litres and it'll spool, you can change fins, but it should give plenty, mine off an 8.0litre engine, and we just did some pump work and boy does it spool up

pity about the steering...BUMMER

The .60 a/r is about average. Usually, the larger the a/r the longer it takes to spool. Expect it to take about 2700 or so RPM to get going, and it probably won't spool up all the way until over 3500. When it hits, it'll probably hit hard (nothing then instant torque and hp).


Oh, and check your PM's.

Cool....
