Again, if you were using a salvaged head, you could work relaxed and patient, taking weeks if that was all the time you had.īlizzy thanks for the solid reply.Your statements are right in line with my way of thinking. I know my buddy used the Eastwood head porting kit (~$30). But, regardless, I am certain there is throttle response and top end performance waiting for you in the head of the engine.
The key would be doing the proper resarch to make sure you wouldn't port the heads to flow way more air than you would need. I am sure you could get a 1UZ head for a hell of a deal with a little searching. I have seen 1JZ heads for sale around $100. With the proper amount of research, you could determine the perfect head modifications for the early 1UZ on stock cams and valvetrain.įor such a job, I would definitely suggest salvaging a 1UZ head and giving it your best shot rather than tearing down your running motor.
Eastwood porting kit software#
He used software to determine the optimal head structure for his engine, took careful measurements, marked off his porting lines, and went to work.carefully. His truck is putting down like 350wtq having invested some $400 into the motor itself.
I have a buddy of mine that did his own headwork with a dremel tool on an old Ford Bronco motor having never done such a job before in his life. Would it be a waste of money? Well, that would depend on the amount of money you spent. With your nitrous spinning the motor hard, you could definitely derive more efficient flow from the engine head with some head work.
