Hello everyone, this board is great. I have grown up running all types of farm equipment, being a auto and heavy truck mechanic, and drag racing. I have always been interested in tractor performance but never knew much about it. I am a International and Kubota fan. I was wondering what performance modifications can be made to increase HP and torque. I am lookin into a International 1466. What can be done? Head work? injectors? Injector pump? Bore motor? Transmission? any websites you all can direct me to for further knowledge. That tractor has 145HP stock. What can i expect i want to notice a big diffrence.
