4b cummins

looking to put a turbo on an anerican 60 tractor with 4b cummins engine, except for hooking up the turbo and lines, what else do i need to do to make this work, like changing the injector pump timing? looks like a plug where the oil returns back to the block, freeze plug? what would you use in that hole to hook up the oil drain?

When I turboed my 706,I changed nothing.Just 'installed' it. I hooked the oil drain to the oil pan.Brazed a 'fitting' to the side of it and clamped a hose to it. I guess it worked......Turbo has been on for 30 years/4000 hrs. 70 horse 706 is now turning 96 horse.Word of advise Install a pyrometer. Dont run it hard without one.Turbos generate a lot of heat,enough to melt a motor.A pyro will tell you what is happening BEFORE the tach moves.or the heat gauge moves.

Actually a turbo should cool down the EGT's, that is if the pump is/was set right. Anyway if a turbo added heat to the EGT's, I'd hate to see how hot they were without the the turbo/boost. You need to find info on what type of pump you have and see if you can perform adjustments to the fuel for the addition of the turbo.

I don't know what type in IP you have but most turbo pumps have an AFC or other type of fuel control that compensates fuel vs manifold pressure. If the the engine already pukes black smoke at mid to higher RPMs then the turbo might already be ok installed without fuel mods. What most IP's do with the addition of a turbo would be an increase in fuel delivery and a possible change in IP timing for the boost.

Non turbo engines can be turboed but remember a non turbo engine won't be built the same as as an engine made for one ie turbo engine has a larger oil pan larger radiator and piston cooling nozzles that spray the bottom of the piston with oil to help keep them cool

Don't forget many have heavier rods and larger size piston pins and journals sometimes.

You have a friend with a Cummins dealership? Take your CPL number and find the CPL number for a 4B with a turbo and see what the timing and other settings are.

(quoted from post at 03:43:55 03/26/15) Non turbo engines can be turboed but remember a non turbo engine won't be built the same as as an engine made for one ie turbo engine has a larger oil pan larger radiator and piston cooling nozzles that spray the bottom of the piston with oil to help keep them cool

AND... lower compression ratio, special top rings, oil cooler of some type.

The turbo compressing air, ups the pressure so the static compression ratio of the engine is lowered, to compensate for that.

Tractors can run under continuous load for long long periods of time, so the egt and heat can destroy the engine quickly. Hyway vehicles get long hills only for shorter periods and speed limits keep the heat down.

Yes bubba has to be real careful when he start throwing parts like a
turbo on engine that wasn't designed for it.

I looked in my White American parts book and shows different piston numbers. The 60 number for standard engine service kit is 30-3455084 and the 80 is 30-3454843. For your info the Case 95XT has the 3.9 with the turbo in it we have one at work. Remember that is only a glorified 1555 trans and rear end in the 60. What year is yours?, mine is a 1989 and my dad and I bought it new and even have a White American pedal tractor. I have new decals for the pedal tractor just never put them on.

I have been told that all small Cummins engines has oil sprayed pistons and all the turbo upgrades. Why they all are indestructible. I would go for it. I have turned my non turbo Case backhoe up to where it is as powerful as a stock turbo backhoe. With a turbo should have 200 HP if put a large enough turbo. That would just 50 HP a hole. Just 300 HP in a 6 cyl. They will put out twice that, and live.
