new take off 2403t exhaust manifold
 
These are not mine! Just passing on the deal. I purchased 2 .

They are center dump at about 45* up. And already have a 4 bolt turbo flange. Not sure what flange though. A very nice option

Hope that works.

Thanks

Hey thanks for the find! I just ordered one, it looks very similar to the turbo manifold off the V2003t that I have with just a little different angle to the flange. This one angles away from the motor, the other is slightly angled toward. These should be a great improvement over the Carrier manifold.

yellow68gto 01-19-2015 12:40 PM

I was planning on making one with similar placement but for the cost this is perfect. Now I have to figure out what flange it is. I'm excited to get it here and mock up the turbo.

Any idea what a good compound setup would be? Or what is better. I have a Saab turbo now but looking for better combo.

FTE 01-19-2015 01:01 PM

The V2003t I have has a TDO3 that bolts to that flange, it looks to be the same as this one. I suppose that could be 1/2 of your compound setup.

yellow68gto 01-19-2015 02:18 PM

At first I will go single but later I would be experimenting with turbos. Maybe a good single is more then enough. Not looking for maximum performance just for good responsive power with little lag

DetroitDiesel 01-20-2015 09:17 AM

They won't ship to Canada :dang: and I keep blowing turbo gaskets left and right. Might have to make my own

yellow68gto 01-20-2015 09:48 AM

That sucks. Have never shipped to Canada but my work has. I will find out what it takes. Maybe you can have it shipped to me and I can just forward it to you via UPS for shipping fees

Edit: I talked with the guys in shipping, if you wanted to go that route and have it shipped to me ,there wouldn't be a problem. So the offer is out there to just cover the extra shipping charge.

JesterGrin_1 01-20-2015 12:48 PM

Thank You for the heads up :c:

FTE 01-23-2015 04:37 PM

Just received the manifold! Looks good and hugs the head a lot more than the others. I should be able to mount the turbo to the side instead of on top and still clear the vacuum booster.

dieselxj 01-24-2015 02:43 AM

I got one coming, but I won't see if for a few months. Hey FTE, can you put that manifold on one of your spares engines and take some pictures?

yall have fun

yellow68gto 01-24-2015 09:42 AM

Got mine.they look nice. I will take some pictures

dieselxj 01-24-2015 02:04 PM

when someone figures out the correct studs size and length or part # for the new manifold I would be interested in that info as well

yellow68gto 01-24-2015 02:54 PM

Still haven't gotten pictures but I know what I am doing Monday! Making adapter to my turbo. I haven't got a pyro yet but what thread are they normally? 3/8 not?

yellow68gto 01-26-2015 02:35 PM

4 Attachment(s)
on these new manifolds there is a threaded boos between port 1 & 2, i was thinking about milling this down and it could be a nice place for the pyro. Is it better to have it where all 4 ports come together or is this place good also?

thanks for the picture.
I am not 100% sure about EGT probe location. maybe someone else can chime in. But my understanding is closest to the exhaust valve is more accurate, assuming all cylinders are firing the same. So from these pictures only, on these new manifolds, it looks like the 1-2 boss is a little bit closer to the fire than it would be at or just cylinder side of the collector. On the other hand at the collector you get a average of all 4 cylinders. With that said I was thinking to still go with the probe in the collector area. or you can try both places and plug the one you don't like.
I did not understand your question from before about the thread for the EGT probe, mine is 1/8" NPT tapered pipe. I think that is pretty common

Sorry about the mistype. I sent that question from my phone and it should have read 1/8 NPT not "3/8 not" was a mix betweeen fat fingering the keypad and auto correct.

I am probably going to do what you suggested and just tap both spots. It is not hard to do.

Thanks
Ken

handcannon 01-27-2015 08:17 PM

The best location would be just below where the turbo mounts. There you would get an average of all four cylinders just before going into the turbo. The temps are more accurate there also.

At the location you are asking about it looks like you would only be reading from cylinder #1 and not picking up much, if any, from cylinder #2. You'll have to look inside the manifold and see what may be in the way of putting the probe there just under the turbo.

yellow68gto 01-28-2015 01:13 PM

I did more research and put it before the collector. I would rather know how all cylinders are acting and if I have an injector foul up would see an egt rise instead of looking at one cylinder and assuming all are the same

I got all my hardware from mcmastercar. I will post the part #s and description tomorrow when I am back in the shop.

yellow68gto 01-29-2015 05:50 PM

Part Numbers for studs from mcmaster dot com

7 pcs- 91059A525 Steel Thread-Locking Adjusting & Positioning Stud, M8x1.25 Thread, 70mm Overall Length, 8mm & 22mm Thread Lengths $1.29 each

1 pc- 91059A510 Steel Thread-Locking Adjusting & Positioning Stud, M8x1.25 Thread, 35mm Overall Length, 8mm & 22mm Thread Lengths $.62 each

1 pack -90591A161 Zinc Plated Steel Hex Nut, Class 8, M8x1.25 Thread Size, 13mm Wide, 6.5mm High, packs of 100 $5.07

I already had 8mm washers here also the manfild collector is 8mm so the nuts work on that also.

so you are looking at $18 maybe total for hardware

can anyone put a name to the turbine flange on the new manifold? I looked and I think it is for a td03 turbo, and FTE confirmed I hope.
I think there might be a break in the flange sizes. where the TD03 turbo uses a different flange, and the TD04, and TD05 I think use the same flange? but that is the actual turbocharger, I want to talk about the exhaust manifold flange
The point is I wanted to look for a turbo that would fit this flange without an adapter if possible.
I still have the measurements from my TD04 chargers gasket. it seems there should be a file or collection of turbocharger flanges for CAD CAM guys

FTE 02-01-2015 10:07 AM

That tdo3 turbo on my 2003t motor is TINY, I don't believe it would be good turbo for our rigs. That said I'm not sure if there are any tdo3 variants that would be better.

yellow68gto 02-01-2015 10:31 AM

There is a td03 on eBay from the 2403t. Also there is a Volvo td03 but the exhaust flange is different but looks like 2 bolts are right and you could possible redrill for the other 2

dieselxj 02-01-2015 04:49 PM

Yes but does the flange on the exhaust manifold have a size? like T3????

yellow68gto 02-01-2015 05:49 PM

I'm not sure. I can try to find specs based on my measurements from making my adapter
