Inchworm Lefty Install: FJ Cruiser Gets a Tummy Tuck

lefty_frontWhen it comes to modifying the FJ my goal has always been to achieve increased capability without negatively impacting vehicle performance. There’s no doubt that a vehicle designed for hardcore off-roading is going to witness its share of bruises. And the greater the number of modifications, the greater the chances that the stock integrity will be affected. My FJ Cruiser began its life as a daily commuter that saw occasional off-road use. Over the last four years of ownership, the scales have definitely tipped in favor of off-roading. It’s still my daily commuter, but my upgrade priorities now lean towards off-road conditions, rather than worrying so much about what kind of mileage I can achieve. To that end, it’s time to roll back the clock once again, to retroactively discuss one of the best possible modifications available for FJ Cruiser owners.

October of 2009 was a great month for my FJ Cruiser, and probably one of the most significant in terms of upgrades. I had spent the previous month or so analyzing my FJ’s performance characteristics in great detail in an effort to determine my next upgrade path. One of the immediate drawbacks to note was performance on inclines. Although the FJ comes stock with a 2.56:1 transfer case gear ratio, the gearing even in LOW/LOW leaves a lot to be desired when it comes to steep hills. Extremely rocky terrain can also prove frustrating since drivers can find themselves in constant “brake” mode, where their foot never leaves the pedal. On flat terrain, riding the brakes can indeed be an effective method for controlling forward momentum. But on inclines where the surface is loose or slippery, hitting the brakes can lead to disastrous results. The question is, what can FJ owners do to improve this situation? Continue Reading →

TRD Performance: FJ Cruiser Gets Supercharged

May 14, 2010 by Engine Mechanical Mods and Modding Toyota FJ Cruiser

IMG_1731When I initially purchased my Toyota FJ Cruiser, engine performance was the last thing on my mind. The 1GR-FE 4.0L engine had more than enough pulling power to meet the needs of the everyday driver.  Even pushing the stock weight of an FJ Cruiser at nearly 4,300 pounds posed no difficulty for this well-built engine. But as time went on and the upgrades continued, the FJ’s love handles began to show and performance wasn’t what it used to be. Mind you, adding on some skids and a bumper isn’t going to turn the FJ into a complete slug. But over time, those who invest in the heftier upgrades will no doubt begin to notice performance degradation. Knowing that my upgrade plans were far from over, I decided it was time to begin looking around for ways to boost the FJ’s horsepower. And rather than building boost in small increments through chips and high-flow exhaust systems, I decided to go with a supercharger solution. At the time of this decision, there were two possible supercharger systems available, one from Toyota Racing Development (TRD) and an alternative system offered by a company named Underdog Racing Development or URD for short. Both offerings were great systems but each had their pros and cons. Continue Reading →

FJ Cruiser: On and Off the Road

November 28, 2009 by 4WD and Traction Aids General Mechanical Off-Roading Transmission and Drivetrain

As a follow-up to yesterday’s article detailing the FJ Cruiser’s core structural components, I’d like to add a few more details, specifically addressing the drivetrain systems.  The FJ Cruiser can be ordered with either a 5-speed automatic or 6-speed manual transmission.  Both of these transmissions are extremely capable.  It really comes down to personal preference as to which model you choose.  I personally prefer an automatic since I’d rather focus my attention on the trail.  But for many, a manual transmission is the only way to drive.  Arguments as to which is better and why are similar to the IFS versus solid axle argument.  There will always be pros and cons to either side.  Even though I tend to lean towards the automatic model, I’ve included videos that provide more details for both transmission models below.
