Ford Ranger 1UZ-FE V8 Conversion

Another great example of how a Lexus V8 (1UZ-FE) conversion should be done.

This Ford Ranger was fully converted and is now running a 1UZ-FE V8 paired with a Lexus 6-speed automatic gearbox.

The result is a clean, reliable and properly tuned setup — built to be driven, not just to look good.

No shortcuts, no compromises. Just a solid conversion done right.

“Cheap Conversions” vs Proper Conversions 🔧🔥

There’s a big misconception that engine conversions are the “cheap option” when your engine packs up, or that a Lexus V8 swap is just a cheap toy.

That assumption is completely wrong.

Here are real examples of what people call “cheap conversions” done by some well-known or busy workshops:

We’re talking about things like:
– Starter wiring joined with a vice grip, taped up and even sealed in a plastic bag
– Engine mountings built with no rubber isolation at all
– Welding that looks like it was done by someone who should never touch a welder
– Wiring that is shocking, unsafe, and completely unreliable

If it’s cheap, you get a cheap job — and then you end up spending even more money fixing it afterwards.

A proper conversion is not just an engine swap. It’s a full, detailed build that takes time and money to do correctly.

When we do conversions, we make sure:
– Everything is done properly and safely from the start
– The cluster works again (rev counter, temp gauge, speedometer, etc.)
– Aircon is integrated and working
– Cooling system is upgraded (radiator + gearbox oil cooler — many skip this)
– Fuel system is upgraded with a proper pump
– Engine and gearbox are serviced before installation
– Correct shifter setup is installed
– A proper Spitronics engine management system is fitted (because stock ECUs are limited, non-tuneable, and outdated)
– Banana branches and freeflow exhaust systems are fitted for proper flow
– And many more!

Our pricing is our pricing — because we refuse to cut corners.

We don’t build conversions to be “cheap.”
We build them to be reliable, safe, and done right the first time.

Built properly. Tuned properly. Ready for the road 👇

Reliable, tunable, and proven control for performance and conversion builds.

From stock ECU limitations to full standalone control — engine and gearbox management done properly.

With over 20 years of experience in the industry, we understand what it takes to make conversions reliable, drivable, and correctly tuned.

Toyota Hilux 3UZ-FE

This Toyota Hilux came in a while ago, fitted with a Lexus 3UZ and 6-speed auto gearbox - conversion not originally done by us. The client experienced issues with the standard factory management system.

We stepped in and upgraded the entire setup with Spitronics Engine Management.

Now the engine, gearbox, and electronic throttle are all fully controlled and properly tuned through Spitronics.

The difference is massive:
Old OEM Lexus management is limited, non-tuneable, and running decades-old wiring and computing technology.
Now replaced with modern, clean, and fully tunable Spitronics wiring and system.

Tuned and ready to perform 👇
