Ford Ranger 1UZ-FE Conversion - Shifter Correction

Ford Ranger Lexus V8 conversion that came in needing some attention to the finishing details.

The vehicle was fitted with a 1UZ-FE V8, but the previous shifter installation involved cutting up the centre console and fitting a very rough shifter setup.

We removed the previous setup and reinstalled the original Ford Ranger shifter, modifying the linkage so that the factory-style shifter operates the automatic gearbox correctly.

Much cleaner result, factory-looking interior, and no unnecessary cutting of the console.

Sometimes the best conversion work is the work you can’t see.

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– A proper Spitronics engine management system is fitted (because stock ECUs are limited, non-tuneable, and outdated)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 👇
