I have a 22r i just rebuilt, it already has an re head. How much of a pain is it to put the intake/plentum on, wiring harness, and fuel pump. i can keep my starter, alt, and guages on the wirin harness i already got. just the other part of the harness i can use. How long you think it would take, and how much extra money. I already got 1200 dollars in my motor so tryin to stay kinda cheap.
