Upgraded T25 exhaust manifold for GTX2867R

[Das Gespenst]

And now I'm looking at the CTS manifold, seems like the best bet as far as bang for the buck and avoiding the terrible ATP log manifold.

Great info in this thread. Keep the personal experiences coming!

Thanks...

Ah thank you. Good to know.

You are welcome.

CTS exhaust manifold is a good option but take care because it is T3 not T25 so you will have to change a lot of things if you go for it.

Bad news

Bad news
I get my engine down in order to wrap the VF Engineering Exhaust Manifold and the Down Pipe and to install new parts. But, I found the VF exhaust manifold I just purchased is cracked :frown:



Also, the ATP housing is cracked too



I contacted ATP and I found .64 A/R Ni Resist housing which is a good option

I contacted VF two times but they didn't even reply to my emails while I was getting an immediate reply before when I was purchasing the manifold!
I am expecting that they will send a replacement manifold if they care about their customers, I hope they care about customers!

I don't want to spend too much money because the IE450T is in my short plan.

Also I am still looking for the APR exhaust manifold.

Today I received the ATP .64 A/R Ni Resist turbine housing.

The material looks different and better than the old one I have.

I will leave you with the pics.











I am waiting for the new VF Engineering replacement manifold and other IE stuff, hopefully to receive it within couple of days to put the car together again and see the results. addle:

That's not the first time I've seen VF exhaust parts crack. I've seen 2 3.2 VR6 manifolds crack amd a 2.5 mani crack. I wonder about their quality, not saying it's crap by any means, but everyone I know that's run them have had issues. I would highly suggest just getting a true tubular manifold built. It's high dollars but with the work you have done why not invest in something truly worth while?

I'm not surprised at the cast manifold issues at all. I am surprised no fabricators have come on here and offered any other options. not sure if they don't want to bother with the vw crowd or what

I don't know why it happened with VF stuff, it seems it's crap!
I am not sure that anyone here in my country can do a good tubular manifold and in all cases I plan to get the IE450T kit so I will use the VF replacement manifold until I get the IE kit.
The only manifold I can go for once it is available is APR stage3 manifold

I contacted many vendors and no one want to sell an individual manifold, the only one I found was CTS T3 manifold with external WG, and purchasing T3 housing and External WG with a new DP were not in my plan that time!

As the engine is out and while I am waiting for the VF replacement manifold so I decided to work on other stuff to save time.

I installed the IE intake manifold and gradually will install other parts, some parts already received and some will be here within few days.
More pics soon.

You may want to modify that new VF manifold to prevent that same cracking. It's clear that it dosnt flow great and the hot gases warped that dividing which cracked the manifold IMO . Bob G

I would clean up all the inside edges so they have smooth transition and no sharp edges , IMO I would also pay special attention on the dividing wall and round all the edges and then mill down that dividing about 2-3 " so it opens up and flows better in that area so heat can't build up warping things.

It is good idea but I am not sure who can do it here! I will share it with my mechanic and see if we found someone can do it or not.

I am thinking to coat the manifold, I am searching for a good company here to do Thermal Coated for the new VF manifold.
The point is I am not sure from the correct material that need to be used for the thermal coat.

Yup. Not a big fan of the ATP manifold either. But its been a year and have not had any timing issues yet. The lag is a pain but manageable. If I do upgrade im upgrading the turbo as well. Love the tubular design.

 

[Alpha_GTi]

Thanx for this. Will be staying well clear of the ATP manifold now. Keen to see how this turns out :thumbsup:

 

[Mostic]

The replacement VF manifold arrived yesterday..

I will try to coat it and try to do what Bob G. advised and hopefully I can find someone who can do, otherwise I will install it as its and pray that it won't cracked too!!

Few updates...

Installed the 4 port methanol nozzles and nozzles holders.

Attached the IE intake manifold to the engine.

Also, checked the Stage8 bolts & nuts sizes to install the Exhaust manifold, Turbine housing and Down pipe.

I will keep updating the thread if you are interested!
