I had the same question with my car and I am sticking with the 1j in my car. I am in it for direct drop in though. I wanted something with good daily drivability and a good power band. I also saw one person say the 1j was cheap and one say it is expensive. It is true that the 1j is getting harder to find at importers but also there are more out there being sold and sold back as a result of poor money management and failed budget requirements in the suspect build up. THis gets you a lot of people who thought they had the time and money selling the clip (or motor) back at a lot lower cost. Don't let shipping scare you. You will be able to ship the clip for under 500 from anywhere in the contiental us and th emotor for even less. My count from NY to FL was 350 and I got a better deal then that in the end. I just got my jzx81 clip for 1500 + shipping so look around and you will find the right deal. Anyways if you want a 7m-gte motor I have a spare one for you : ) The aftermarket parts for the 7m over the 1j is another plus, Front facing intake manifolds are available which to me definetly dresses the 7m up. Check supramania supraforums and other supra resources to get the skinny on the motors. We can only tell you from personal preference and your assumed needs. It is you who knows exactly what you want and you need to get that from both our input and your own research

PS don't the NA cams only increase power in pre 89 motors. And the 6m crank can't hold massive amounts of power as it is known they break around the 600 mark ,but that is more then you want, the reving will be an issue but a head job is right around the corner.
