What are the key differences in 1030's and 1070's? If I were to swap a 451 from a 1070 into a 1030 would any modifications be needed, and are there any real downgrades in going from a 1972 model 1070 to a 1969 1030? Thanks a lot.

Ouch. Roger in (Mi), 145hp in a 1030 or 300hp in a 1070 ? Aftermarket turbos on naturally asperated Case 451 motors tends to kill tractors. I think a person could forget everything I said about them being simple, tough, reliable, economical tractors. Although the noise part holds true I am sure. Around here decent 1370's and 2670's go for about $5000. A decent turbo setup will cost about 1/2 that. Then you would but it on tractor with 6000 to 9000 hours, is that a good idea ? I think I would just buy a bigger tractor.

 It's economy too... in reply to Chris in ND, 09-29-2007 14:23:12  
Certainly, Chris has a valid point. If need big horsepower on a day to day basis, buy a bigger tractor. The size, weight, and parts reliability are greatly enhanced. Putting a turbo on a smaller tractor goes beyond an increase in power. My son and I put a turbo on a 970 a number of years ago. The pump was turned up and there was a maximum of 113 horsepower on the dyno without the turbo. We left the pump at the same setting but added the turbo. The horsepower jumped to 176 horsepower. What's the point? Waisted fuel! We were using 176 horsepower worth of fuel but only getting 113 horsepower! We were able to turn the fuel adjustments way back and still had far more horsepower than before. The turbo setups were taken from stock Case tractors which had turbos at a tractor salvage yard for $250 - $3oo. We have yet to experience any drive train or engine failure because of adding turbos. My son is in partnership with a fellow in Wisconson. They have a Pro-stock 1090 Case tractor that is putting out more than 1,500 horsepower. Most of parts in the drive train and rearend are stock. Want to see this critter run? It will likely be at the National Farm and Machinery Show in Louisville, KY in February.

 Big power difference (with a turbo) in reply to Ethan Jones, 09-27-2007 14:21:17  
I own both a 1030 and 1070 among other Case tractors. The 1030 is still my favorite. Yes, there is a big difference in power if both have turbos installed. My 1030 with a turbo has a max of 145 horsepower with the pump turned up. I've turned it back to 125 horsepower. The 1030 power cell heads handicap the engine for potential power increases. The direct injection heads on the 1070 is a different story. With its cross flow heads, a turbo installed, and the pump turned up, 300 or more horsepower is on tap. Because of the direct injection cross flow heads on the 1070 engine, hood sheet metal work will be required. Some linkage and fuel changes will need to be made. If you want the potential of big horsepower, changing to the '70 engine is the way to go.

I don't think you would be giving up much. The 1070 might have powershift, the 1030 will not, but I am not sure that is a disadvantage in a nearly 40 year old tractor. Those manual transmissions with the hi/low range were seemingingly indestructable. Most of the 1070's around here have 3 pt hitches, I haven't seen any 1030's that do, but it was an option. I have never seen a 1030/1070 engine swap but have seen a late 930/970 swap done. That worked fine. Don't get rid of the 1030 engine or any of the brackets untill your done. We no longer farm but still have a 1030 and we love it. It mostly disc's weeds in the tree rows,runs the pto generator at near idel and pulls the kids pickups out of the mud. 1030's are tough, simple, reliable tractors, they sip fuel, althought they are a bit loud (earplugs require) and like ether on cold mornings.
