I sold my 2008 Audi TT 3.2 and am looking at making a few upgrades to my 4Runner. I ordered an RCI Gas Tank skid and a Bad Elf GPS unit for my iPad 2 - both much needed additions to my overland setup. Here is my tentative plan moving forward.
With the V6 and 33 inch tires, the stock 3.727 gearing is too low for Vermont's Green Mountains. It is tolerable, but it runs at 1,500RPM to 1,700RPM when cruising at 70MPH on the highway, and when I tow a small 5x7 utility trailer empty there is a very noticeable reduction in power. I'd like to get some pep back and cruise around 2,500-2,800 when cruising on the highway. I'm most likely going to 4.56 gears, although there seems to be some thought on the forums that 4.88 is the better choice for 33's with a V6. I need to do more research on this - the truck sees the highway regularly and I don't want my gearing too high.
I'm adding an ARB locker in the rear end. As a temporary daily driver for the next 6 or so months, I'm reinstalling the front sway bar for safety reasons and am not interested in removing it every time I go off road. I will lose some suspension articulation and the locker will make up for that loss of traction. I'm not doing an ARB in the front because I think it is unnecessary with respect to the way I use the truck and I don't want to strain the front CV's. Furthermore, Toyota's A-TRAC is really good at keeping the truck moving forward anyway so my new setup will essentially be a locked rear end with a limited slip in the front - damn near unstoppable. I'm also looking forward to having an on-board air source again for airing up my tires after a day on the trail.
I've made arrangements to have my front and rear bumpers sandblasted and either re-painted or re-powder coated. Performance Unlimited in Woodstock, VT suggested I have them repainted because they will then be easier to maintain and touch up many years into the future. While the bumpers are off the Ramsey Patriot Profile winch will be overhauled, the truck will receive a waxoyl spa treatment along with it's annual buffing and waxing. When I get the bumpers back, I'll be installing a JW Speaker reverse light, two new JW Speaker TS3000R spot and flood lights, and two new JW Speaker 4" fog lights and am looking into an S-pod designed for the FJ Cruiser to control all of the electronics. I'm back to running one set of factory wheels, and I'm thinking about having them sandblasted and refinished in an anthracite color while all of this work is going down.
This plan is a ton of work and resources, but the end result is a very clean, reliable, and capable rig that with any luck will last another 100,000 miles+.
