The swap really isn't all that hard. Once you decide where in the engine compartment you are goint to put it(such as, lower, further back), they you can decide how your motor mounts should be. That is one of the harder parts.
I have now done 3 of them in trucks, 2 in cars.
One in my 4runner with 2" body lift, then I lifted the drivetrain up 2 inches and back 2 inches. Was v6
Time: 34 hours, but that included auto to manual conversion, and a dual t-case, with front range off-road x-member.
Helped on a 93 pickup, no body lift, but lifted drivetrain 2 inches and back 2 inches(had to cut out tranny tunnel and build new one), was v6.
Time: 30 hours over a month, and this included extra wiring for the Auto and auto ECT controller.
92 2wd pickup 4cyl. Used stock engine mounts in truck and 5m mounts on the motor. motor sits a little high, and because it was high, required slight hammer adjustment on a couple places on the firewall, but nothing serious.
Time: 24 hours over a week.
You can't beat the power. You don't even need lexus afm and 550cc injectors to get to 400 hp. I got 260 rwhp +35% for drivetrain, is around 400hp, and 400ft/lbs of torque. All I have is an upgraded stock turbo which isn't really doing me any good because I can't run over 11psi without leaning out too much because my fuel system needs to be upgraded. With more fuel, my setup can handle 20-25 psi.
I highly recommend this swap. I am planning on doing another swap in my 89 2wd pickup early next month. I actually just ordered 3 more 7MGTE's today.
