1JZ 2JZ installation instructions for dummies,2 weeks, drive it! Read this entry. It is pinned to the Toyota L6 forum. Then research the web for front cut with 1jzgte or 2 jzgte motor. It will have all the wiring included. It will also have gauges. It will save alot of time and effort for you. There are other ways to go about it. This seems to be one of the most straight forward way to do it.Source a custom driveshaft. Go to www.betamotorsports.com for engine mount/ crossmember. There are a number of other small things. No one can tell you exactly what it will cost for you to do this. Are you going to do the fab work yourself? Is someone else going to do it for you? The cost goes up or down depending on this. Just my .02. To get an idea of the cost do the research and add it up. I do not think there is a whole lot of cost difference between the jz motors and the rb motors when all is said and done.
