Step-by-Step Guide to Restoring and Upgrading an FJ40

1. Chassis and Bodywork Restoration

Body-off Restoration: If the existing body is rusted or beyond repair, replacing it with an Aqualu aluminum tub can be a great solution. Aqualu’s high-quality aluminum replacement bodies provide durability and a seamless look.
Seam Addition for Authenticity: The Aqualu body does not come with factory seams, so adding a fake seam helps maintain the original aesthetic.
Powder-Coated Frame: While this step is typical in a Stage 3 restoration, ensuring a strong foundation is crucial for longevity.

2. Suspension & Steering Enhancements

Shackle Reversal Kit: This modification significantly improves the ride quality both on-road and off-road. Available as a kit, this is one of the best drivability upgrades for an FJ40.
60-Series Power Steering Conversion: Keeping it within the Toyota family, this modification ensures smoother handling. However, earlier FJ40 models (pre-1979) require a Saginaw power steering pump as they lack factory provisions for a Toyota pump.

3. Engine & Transmission Upgrades

2F Engine Swap: The Toyota 2F engine provides improved reliability and performance over earlier versions.
H42 4-Speed Transmission: Upgrading from the stock 3-speed transmission allows for smoother shifts and better highway performance.
Air Conditioning Installation: Adding a Vintage Air Gen 4 AC system ensures comfort in hot climates.

4. Braking System Improvements

Disc Brake Conversion: Swapping in front disc brakes from a later model greatly enhances stopping power and safety.
80-Series Brake Booster Upgrade: Using a 1991-1992 Toyota Land Cruiser 80-Series brake booster and master cylinder results in significantly improved braking performance.

5. Interior & Comfort Enhancements

Seats: Original bucket seats are often difficult to find; Corbeau sport seats offer a good aftermarket alternative.
Dakota Digital Gauges: A modern gauge cluster improves visibility and adds a contemporary touch while keeping functionality intact.
3D Printed Stereo Delete Plate: If retaining a vintage look, a stereo delete plate keeps the dashboard clean.
Custom Speaker Mounts: Finding the right spot for speakers in an FJ40 can be tricky, but custom MDF enclosures provide an elegant solution without sacrificing passenger space.

6. Exterior Details & Finishing Touches

OEM Wheels & Hubcaps: Retaining the factory wheels and hubcaps preserves the Land Cruiser’s classic look.
Kenda Klever Tires (33×9.50R15): A newly released tire that maintains the old-school aesthetic while offering modern performance.

7. Community & Enthusiast Culture

The Land Cruiser restoration community is vast, but engaging with online forums and social media groups can be hit or miss. Enthusiasts should foster a more welcoming environment for newcomers, offering guidance and support instead of criticism.
