    Bo-Ported Gnari Manifold - Kinda New.....just better......

    I am selling my been-installed-on-the-engine-but-never-run Bo-Ported Gnari manifold that has had its external surface smoothed/deburred and has been ceramic coated. The intention with smoothing the exterior of the manifold was to help extended the life of the ceramic coating. I would totally be running this manifold on my car if I had not been presented with several upgrade options after purchasing it.

    As stated, this manifold has never been run on the car, just installed on the engine for the fabricator. There is a small spot on the face of the header where the ceramic coating was hit and a fleck is missing. I am not sure if this will have an adverse effect on the longevity of the coating, but wanted to state nonetheless for full disclosure.

    To sum up what I am including with this sale:


    • Bo-Ported Gnari Header with black ceramic coating that flows @ 144 CFM after porting.
    • 2 bolt to 38mm V-Band Adapter (installed)
    • 2 bolt external wastegate block off plate
    • All hardware for installation.


    To explain what brought me from purchasing this manifold to the point of selling this, below is a list of the events that transpired. I do have a bad tendency to get long winded with the journey my car has taken me on, so I am going to try to bullet point the events:


    • 05/19: State Inspection on my 1984 SVO failed for manifold leak at #1 flange/mating surface.


    • 07/19: Decided to give Gnari a shot with buying something new without having to re-plumb my exhaust for a center mount, with every intention of keeping the stock turbo with the internal wastegate (but to have room to upgrade at a later date).


    • 08/19: Shipped the manifold to Bo to have him port and flow test it
      (If you follow Bo-Port on FB, this is Gnari manifold was the one he posted the flow numbers on in August of last year)
      While at Bo's, he performed some of "external porting" (AKA smoothing/prepping the rough areas) of the cast iron for the ceramic coating I would be doing


    • 08/19: Manifold was ceramic coated black by a local vendor.


    • 09/19: Was presented with an opportunity to buy a turbo upgrade, that came with an external wastegate, for a very good price. <----this is where I made my life more complicated!
      • This turbo upgrade would require fabrication for the outlet elbow and dump pipe, which was tricky due to the new turbo's outlet clearance to the firewall. Being that I do not possess any welding skills, this required me to locate a competent pipe fabricator.


    • 10/19 - 02/20: Locating a pipe fabricator delayed to the choice to upgrade to sequential fuel and having to make harness changes. OH yeah.....and winter......


    • 03/20: Fabricator located, car delivered to the fabricator's shop for him to work on it when he had time.


    • 04/20: The seller of the upgraded turbo I purchased in 09/19 wound up listing the header that he used to run the turbo and wastegate on. On top of it being a better flowing design than the cast Gnari (and it being made from schedule 10 stainless), it also moved the turbo forward and up to provide more clearance for the fabricator to do his work.


    • 07/20: Thanks to COVID, and such life complications that have been experienced, pipe fabrication completed and car is back up and running. It is at this point that I was willing to part with the Gnari.


    Here are photos of the before, during, and after porting:




    I paid $290 for the manifold, $300 for the porting and external smoothing, $30 for the Vband Adapter, and $100 for the coating.

    I would like to get $500 (shipped) for everything, but am willing to discuss reasonable offers. As far as delivery of the item, I can also bring to the Carlisle All Ford Nationals in PA next weekend if you would like to pick it up there.

    Thanks for suffering through my lengthy post. I just wanted to be perfectly clear that there is nothing wrong with the item and that it is just a crazy sequence of events that has led me to sell it.

    IRSmart21,

    So can this still be used for a stock 85.5 turbo, top mount inter-cooler? Is this the manifold that moves the turbo away from the head by .5"? If so, will that effect the stock turbo / inter-cooler / 3" downpipe mount points and so-on? Interested!

    Thanks!

    Yes, this is the manifold that moves the turbo away from engine about 1/2" and is designed to work with a stock engine configuration. I am not able to answer with confidence as to what kind of effect it will have on the intercooler and exhaust outlet to 3" downpipe alignment. I am running a FMIC and I never mounted my stock turbo in the car on this manifold because by the time I was able to put the manifold in the car I had my new turbo and never bothered to try the stock one.

    My thoughts on it, however, is that you would need a slightly longer intercooler to throttle body coupling and, if you are running your 3" exhaust with Torctite clamps, you might need to loosen up your downpipe to mid pipe clamp to give you a little pivot room to get everything aligned.

    I am fairly confident that there has to be someone on this forum (or several of the other 2.3T forums) that could answer you with real world experience (instead of my theoretical understanding) about the stock mounting particulars/challenges that might be faced with using the Gnari manifold.

    Sorry I couldn't provide a direct answer to all of your questions. Feel free to reach out with any more questions you might have.

    Thanks for the answers IRSmart21,

    Is this the EGR delete manifold (from what I could see in your pictures)? You mentioned the installed v-band adapter as well, is that on a separate piece (the turbo exhaust / o2 sensor housing)? I didn't see that in your pics anywhere..

    Thanks!

    Yes, it is the EGR delete manifold. I had ordered it with the EGR port (so that it was more like the stock manifold) and they wound up sending me the deleted one. :-/ I decided to just roll with it and keep this one. I couldn't imagine it being too difficult to drill and tap a hole for the EGR fitting.

    Here is a link to the 2 hole to v-band adapter I purchased:

    I do not have a current photo of it on the manifold, but I have added three photos to the Google Photo album that show the adapter with my current external wastegate on it. I will be back home on Wednesday, so I could snap a photo of it and share it to the album then.

    Hope that helps!

    Excellent, thank you for the info. Let me consider if this will work for me, I'll let you know asap.

    Thanks!
