Does anybody know what turbo you would need to run a 4bt with an A-pump?

Stock, I believe, would have been an H1C with a 16cm exhaust housing.
An UPGRADE is an HX30w with a 6cm exhaust housing.

It cant be wastegated and we're aiming for 800hp
You can aim for that, but 400 - 500hp is what most are pushed to, from what i've read anyhow. Try http://www.4btswaps.com. There is a member putting a 4 valve common rail head on one with an A pump and compounds.

Change in plans, we just bought a 13mm p-pump with ag governor that's supposed to put out 800cc of fuel. So does anybody know what turbo to run with this pump? :charger:

The more information you can give us as far as what you are trying to do, the more we can help you. And that is putting it very nicely.

4)Engine must be compression ignition and use #2 Diesel Fuel* only. No spark plugs or alcohol as a fuel.
5)Hitch height up to 15 inches allowed
6)Engine must be commercially produced with at least 1000 units built. Engine block must have factory casting model and serial numbers visible. O.E.M. block cannot be altered in any way externally except for normal repair or for mounting fuel injection pumps.
7)Maximum of 4 cylinders
8)May be liquid or air cooled.
9)No belt driven cooling fans. Electric fans only.
10)O.E.M. head for that make/model engine only. No billet or aftermarket heads. No overhead cams. Maximum of 2 valves per cylinder. Injectors must remain in stock location.
11)No billet injector pumps. No electronic or common rail injection systems.
12)Tractors are allowed a single (1) turbo charger with any manifold modifications necessary to mount the turbocharger. Manifold pressure may be a single stage only.
13)Turbocharger must be single shaft fixed vane type. No variable vane turbochargers allowed. No inlet or outlet size restrictions.
14)Turbo must be fitted with a shutdown guillotine on the compressor inlet side of the turbo.
15)Turbochargers not under the hood will be completely shrouded with steel .060” or thicker, except for inlet and exhaust pipes. Turbochargers under fiberglass hoods must be shrouded, except for the inlet and outlet pipes, with .060” steel or thicker under the area of the fiberglass.
16)No wastegates or pressure reliefs of any kind permitted. All compressed air to enter the intake manifold.
17)All turbocharged engines are required to have one cable that must surround the engine block and head. This cable shall be located between the first and second cylinder through the exhaust manifold port area. The cable will be a minimum of 5/16” thick with two (2) clamps at the splice. The cable should allow for approximately 4” of slack.
18)Water injection will be allowed. Must be plain water or water with water soluble lube only. Combustible agents (alcohol, oxygenators, etc.) are NOT allowed in water injection.
19)No intercoolers or after coolers
20)No propane, nitrous injection or any type of secondary fuel system of any kind will be permitted.
21)Any stock appearing frame rail or tube frame is permitted. Tube frame must be covered with sheet metal.
22)Full metal side panels to cover engine area. Minimum .060” steel or aluminum
23)All inline engines are required to have an additional inner side shield consisting of .125” (1/8”) thick steel or titanium OR .250” (1/4”) aluminum inside of the current .060” steel or aluminum side panels with a minimum of .500” (1/2”) air gap. This shield is to be independent of the side panels and must be solidly attached at the top and bottom (4 point total minimum) with a minimum of 5/16” fasteners. This shield must extend from the bottom of the head to the centerline of the crankshaft and extend the full length of the block on each side of the engine.
24)All tractors must have a fuel shut-off AND an air shut off mounted in the drivers’ compartment and within reach of the driver. Fuel shut off must return fuel to tank or loop back to pump.
25)Kill switch device mounted on rear of tractor must disconnect power to the electric fuel pump along with activating turbocharger guillotine.

We're using a 4bt cummins with a 2 valve head, bored roughly .020 over. For an injection pump we are using a 13mm p-pump with ag governor that's supposed to put out 800cc of fuel. For an exhaust we are building our own out of 2" stainless, not sure on flange but thinking a t4.

Why do you have to post something like that. Now I am wanting to make a trip up there to get it.

Looking at your rules would a chassis like that fit the rule book? Reading it it is supposed to have a factory looking compact tractor chassis. I'm asking as I'm thinking of building something similar. My 4b ranger is fun as crap but I have a spare motor sitting here along with a p3000 pump and am contemplating dabbling in the tractor pulling world some as I don't have as much interest in truck pulling anymore

Yes a chassis like that would work.
