4020 with 466 May 13, 2009 12:11AM
Is there an exhaust manifold we can use to get the turbo under the stock hood on a 4020? Tractor is stock except the 466. Thanks.

Not sure but you might try one off a 4320.

I wasn't sure the 4320 manifold would bolt on the 466 head. Will it? If so that looks like it would work.

I am pretty sure that the 4320 manifold would fit on the 466 head. We have put a 4430 manifold on a 4010 head and also on a 466 head.

I have been told that a 4320 hood is wider than a 4020 so the turbo might still hit the hood. Also, I am not sure if you ever said what turbo you were running. I don't know about the 4320 manifold but a 3lm turbo will not fit on a stock 4430 manifold so I am assuming that it will not fit a 4320 either.

Yes we are going to run a stock 3LM. I think we would need an adapter plate for the turbo to the housing........

Here is a picture of one that I made for a 4010 using a 4430 manifold. I could make you one if you want.

Hey JD 466- what rod/wire did you use to weld on that manifold?

I used ni rod but the plate is also made of cast iron.

nicest setup I saw was a regular 4010 manifold with exhaust outlet cut down and a flange made onto manifold for turbo to bolt on, then madeup the elbow to go out original hole. You could get a combine manifold and mount turbo in front but you would have to put exhaust out side screen. If using a stock charger with a stock manifold for 466T it will clear by maybe a finger width but anything bigger than a TO4 it will hit, unless you put a bubble in hood. Someone used to offer a fiberglass hood with a scoop already in it for like $500, but not sure who it was. Anyone have any idea?

I made a manifold to mount a 3lm turbo under the hood of a 4010. It was a 4430 manifold and I machined the riser off of it that goes up to the turbo. Then I machined a plate and welded it to the manifold. There is not much room but it does fit under the hood.

Do you have one you want to sell or will you make another one?

I don't have one to sell but I would make you one if you have a 4430 manifold. I will check with my buddy to be sure that it was a 4430 that we used.

It can be done, with no cutting of the hood. We have built four of them. Give me a call 605-661-4972.

i use a manifold off of a 7810and a 3lm and it fits under the hood but intake side touches on the inside of the hood but it also makes the exhaust go out the back

Will it miss the hydraulic valve?
